<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES
PREFACE<br />
This four-day training course called "<strong>FSUTMS</strong> <strong>Comprehensive</strong> <strong>Modeling</strong> <strong>Workshop</strong>” will<br />
provide an overview of the transportation planning process, travel demand forecasting<br />
methodologies, and <strong>FSUTMS</strong> modules under Cube. Participants will learn the underlying<br />
theories of modeling and see the benefits of Cube's abilities to produce presentation<br />
graphics for reports and meetings.<br />
To aid transportation professionals in Florida, the Florida Department of Transportation<br />
Systems Planning Office has developed workshops teaching <strong>FSUTMS</strong> powered by Cube<br />
Voyager. The workshops will present the transportation planning modeling methods<br />
currently accepted in Florida:<br />
1) <strong>FSUTMS</strong> <strong>Comprehensive</strong> <strong>Modeling</strong> <strong>Workshop</strong><br />
2) <strong>FSUTMS</strong> Executive Summary <strong>Workshop</strong><br />
3) <strong>FSUTMS</strong> Model Calibration <strong>Workshop</strong><br />
4) Advanced <strong>FSUTMS</strong>-Cube & Scripting <strong>Workshop</strong><br />
5) <strong>FSUTMS</strong> Transit <strong>Modeling</strong> <strong>Workshop</strong><br />
6) FHWA Mining Data for Transportation Planning<br />
7) Introduction to ArcGIS Using <strong>FSUTMS</strong>/Cube (to be developed)<br />
Note: Others may be added as requested by the users in Florida.<br />
The <strong>FSUTMS</strong> <strong>Comprehensive</strong> <strong>Modeling</strong> <strong>Workshop</strong> will provide an overview of the<br />
transportation planning process, travel demand forecasting methodologies, and <strong>FSUTMS</strong><br />
modules and data requirements. Participants will learn to install and execute <strong>FSUTMS</strong><br />
powered by Cube, use the menu systems, interpret and create standard output results, and<br />
create and edit networks through a series of hands-on computer exercises. Previous<br />
Geographic Information System (GIS) experience is helpful for this workshop, but not<br />
required. There will be two workshops lasting four days each.<br />
The <strong>FSUTMS</strong> Executive Summary <strong>Workshop</strong> will provide an overview of the<br />
transportation planning process, travel demand forecasting methodologies, and <strong>FSUTMS</strong><br />
modules under Cube. Participants will learn the underlying theories of modeling and see the<br />
benefits of Cube's abilities to produce presentation graphics for reports and meetings. This<br />
workshop will be designed for managers and non-modelers. There will be one workshop<br />
and it will last one day.<br />
The <strong>FSUTMS</strong> Model Calibration <strong>Workshop</strong> will provide the participants technical details<br />
on the <strong>FSUTMS</strong> process and is designed for transportation professionals who have a basic<br />
understanding of the travel demand forecasting process. The workshop contains lectures on<br />
travel survey techniques, how to create <strong>FSUTMS</strong> input files from origin and destination<br />
survey data, how to create and interpret trip tables, usage of friction factors and K-factors,<br />
calibration/validation techniques, and criteria, procedures, and accepted standards in<br />
Florida. There will be one workshop and it will last three days.<br />
<strong>FSUTMS</strong> <strong>Comprehensive</strong> <strong>Modeling</strong> <strong>Workshop</strong> – Preface Page 1
The Advanced <strong>FSUTMS</strong>-Cube & Scripting <strong>Workshop</strong> is designed for the<br />
<strong>FSUTMS</strong>/Tranplan modeler transitioning to <strong>FSUTMS</strong>/Cube-Voyager, as well as who<br />
requires an overview on interpreting and creating Cube scripts under the Florida standards.<br />
The first part of the workshop will cover procedures done differently in <strong>FSUTMS</strong>/Cube-<br />
Voyager and the second part of the workshop will cover Cube scripting language elements,<br />
resources, and data manipulation. Detailed descriptions of the standard <strong>FSUTMS</strong> menu<br />
interface scripts will be discussed. A guest modeler with extensive Cube script writing<br />
experience will be invited to help prepare and teach this workshop. It is recommended that<br />
the <strong>FSUTMS</strong> <strong>Comprehensive</strong> <strong>Modeling</strong> <strong>Workshop</strong> serve as a prerequisite to this workshop<br />
or extensive experience in <strong>FSUTMS</strong>/Tranplan. There will be two workshops lasting three<br />
days.<br />
The <strong>FSUTMS</strong> Transit <strong>Modeling</strong> <strong>Workshop</strong> is a three-day training course designed as a<br />
beginning- to intermediate-level workshop for professionals with highway modeling<br />
experience but little experience in transit. The course will cover in detail transit modeling<br />
within <strong>FSUTMS</strong>-Cube, including transit network coding, micro-coding fixed guideway<br />
stations, creating transit input files, transit access and path-building, Public Transport (PT)<br />
module scripting, mode choice, transit assignment, interpreting and displaying transit<br />
ridership results, and User Benefits. There will be two workshops lasting three days.<br />
The FHWA Mining for Data <strong>Workshop</strong> provides a one-and-a-half-day hands-on training<br />
using data from the Census Transportation Planning Products (CTPP) program, the<br />
American Community Survey (ACS), and the National Household Travel Survey (NHTS).<br />
Course topics include analyzing, troubleshooting, and presenting CTPP data; working with<br />
statistical margins of error; and downloading information from the online tools American<br />
Fact Finder, CTPP Access Tool, and NHTS Online. There will be one workshop lasting one<br />
day.<br />
Introduction to ArcGIS Using <strong>FSUTMS</strong>/Cube will teach the ArcGIS graphical interface of<br />
Cube 5. This new version of Cube combines the usefulness of Cube/Viper's transportation<br />
model display tools with the world standard in GIS software, ArcGIS. It is recommended that<br />
the <strong>FSUTMS</strong> <strong>Comprehensive</strong> <strong>Modeling</strong> <strong>Workshop</strong> serve as a prerequisite to this workshop.<br />
This workshop will be developed after Cube 5.0 has been released and distributed in<br />
Florida.<br />

<strong>FSUTMS</strong> <strong>Comprehensive</strong> <strong>Modeling</strong> <strong>Workshop</strong> – List of Registered Attendees Page 14
GLOSSARY OF TERMS<br />
Access<br />
Connectivity between a TAZ and the network. Access can be distinguished between<br />
highway and transit networks, and between automobile and pedestrian modes.<br />
Alightings<br />
The number of persons getting off a transit vehicle.<br />
Area Type<br />
Network link code representing the type of land use in the area.<br />
Attraction<br />
The desirability of a zone. For non-home-based trips, attractions in a zone can be<br />
considered synonymous with trip destinations in that zone.<br />
Auto Occupancy Rate<br />
Average number of persons per vehicle.<br />
Best Path<br />
One of many paths between a specific origin and destination pair in a transit network<br />
determined to be the most efficient means of traveling from the origin to the destination.<br />
The default transit path methodology used in Florida.<br />
Boardings<br />
The number of persons getting on a transit vehicle.<br />
Calibration<br />
A process where models are adjusted to simulate trip-making characteristics of<br />
households in the model study area to match observed traffic activity in the study area.<br />
Capacity<br />
The maximum number of vehicles that can pass over a given section of a lane or roadway<br />
in one direction (or in both directions for a two-lane or three-lane highway). It is the<br />
maximum rate of flow that has a reasonable expectation of occurring. The terms<br />
“capacity” and “possible capacity” are synonymous. In the absence of a time modifier,<br />
capacity is an hourly volume. In expressing capacity, it is essential to state the prevailing<br />
roadway and traffic conditions under which the capacity is applicable. The capacity<br />
would not normally be exceeded without changing one or more of the conditions that<br />
prevail.<br />
<strong>FSUTMS</strong> <strong>Comprehensive</strong> <strong>Modeling</strong> <strong>Workshop</strong>– Glossary of Terms Page 15
Cordon Line<br />
An imaginary line encircling a study area. Traffic counts, travel origins and destinations,<br />
and other traffic data are collected at the locations where the imaginary line intersects the<br />
roads entering and leaving the study area. Used in modeling to estimate traffic entering<br />
and exiting the study area.<br />
Cube Voyager<br />
A modeling software, developed by Citilabs, used as a modeling engine for the Florida<br />
Standard Model.<br />
Demand<br />
A desire for travel from an origin to a destination. Demand is not a fixed amount of travel,<br />
but a function of level of service.<br />
Destination<br />
Location to which trips are made, variously identified as a zone of specified area (in<br />
aggregate travel forecasting) or a location with a specified “attraction power,” measured<br />
by things such as employees (for work trips) or square feet of sales area (for shopping<br />
trips).<br />
Desire Line<br />
Lines on a map representing the number of trips between zones. The thicker the line, the<br />
larger the number of trips.<br />
EE Trips<br />
External-External trips represent trips that travel through but have both trip ends outside<br />
of the model study area.<br />
Facility Type<br />
A network link code representing the type of service a roadway provides, such as<br />
principal arterial, minor arterial, collector, etc. The facility type does not always match the<br />
functional classification, as the facility type is used for modeling purposes only to simulate<br />
actual conditions.<br />
Friction Factors (F-Factors, FF)<br />
Reflects the regional sensitivities toward certain trip lengths for certain trip purposes. For<br />
example, home-based shopping trips may tend to be shorter than home-based work trips.<br />
Used to modify impedance during trip distribution.<br />
Gravity Model<br />
A mathematical model of trip distribution based on the premise that trips produced in any<br />
given area will distribute themselves in accordance with the accessibility of other areas<br />
and the opportunities they offer.<br />
Headway<br />
The amount of wait time between arrivals at a given transit stop for a given transit line.<br />
<strong>FSUTMS</strong> <strong>Comprehensive</strong> <strong>Modeling</strong> <strong>Workshop</strong>– Glossary of Terms Page 16
Highway-Only Model<br />
A model that only includes a roadway network thereby excluding transit.<br />
Home-Based Trip<br />
A trip with one end at the residence of the person making the trip.<br />
HOV Trips<br />
High Occupancy Vehicle trips, or carpool trips, represent the number of trips with usually<br />
two or more persons in the vehicle, including the driver.<br />
Impedance<br />
More general than Friction Factors, impedance shows the effect that various levels of<br />
time and cost will have on travel between zones. Impedance can include various types<br />
of time (walking, waiting, riding, etc.) and cost (fares, operating costs, tolls, parking costs,<br />
etc.). Other factors, such as comfort, convenience, personal safety, etc., may also be<br />
included.<br />
IE Trips<br />
Internal-External trips represent trips that have one end inside the model study area and<br />
one end outside the model study area.<br />
II Trips<br />
Internal-Internal trips represent trips that have both ends inside the model study area.<br />
Intrazonal Trip<br />
A trip with both its origin and destination in the same zone.<br />
Kiss-and-Ride<br />
A type of transit trip characterized by a transit rider being dropped off at a transit station<br />
by automobile and boarding a transit line.<br />
Level of Service<br />
Multidimensional characteristics of the transportation service provided that are usually<br />
identified specifically by the location of the origin and destination of a trip and that are<br />
divided into those that are quantifiable (travel time, travel cost, number of transfers) and<br />
those that are difficult to quantify (comfort, mode image).<br />
Link<br />
A basic component of a network representing a segment of roadway. This component is<br />
a primary unit of analysis and carries data pertaining to roadway characteristics, traffic<br />
volumes, and performance measures.<br />
Micro-coding<br />
A transit modeling technique used to introduce a higher level of detail at transit stations<br />
by separating access points between modes and introducing links connecting them.<br />
Allows for a more realistic representation of transferring between modes.<br />
<strong>FSUTMS</strong> <strong>Comprehensive</strong> <strong>Modeling</strong> <strong>Workshop</strong>– Glossary of Terms Page 17
Mode Choice<br />
Mode choice models calculate which trips will use the highway network and which will use<br />
the transit network. The model predicts how the trips will be divided among variable<br />
modes of travel.<br />
Mode of Travel<br />
Means of travel such as auto driver, vehicle passenger, mass transit passenger, walking<br />
or bicycle.<br />
Nested Logit Model<br />
Analytical form for demand modeling that is suited to modeling of multiple travel choice<br />
situations by grouping different modes of travel according to their likelihood for direct<br />
competition.<br />
Network<br />
Set of nodes and connecting links that represent transportation facilities in an area.<br />
Attributes normally associated with links are distances, levels of service, capacities, and<br />
volumes.<br />
Node<br />
A point where two links join in a network, usually representing a decision point for route<br />
choice but sometimes indicating only a change in some important link attribute.<br />
Occupancy Model<br />
Converts person trips to vehicle trips using auto occupancy factors.<br />
Origin<br />
The location of the beginning of a trip or the zone in which a trip begins.<br />
Park-and-Ride<br />
A type of transit trip characterized by the act of parking at a transit station and boarding<br />
a transit line.<br />
Path<br />
A set of links representing a possible route between an origin and a destination. There<br />
can be a number of paths between any specific origin and destination pair.<br />
Peak Period<br />
The period during which the maximum amount of travel occurs. This may be one or more<br />
hours. Generally, there is a morning peak and an afternoon peak and traffic assignments<br />
may be made for each period.<br />
Productions<br />
The number of home-based trip ends in the zone of residence. For all non-home based<br />
trips, productions are synonymous with origins.<br />
<strong>FSUTMS</strong> <strong>Comprehensive</strong> <strong>Modeling</strong> <strong>Workshop</strong>– Glossary of Terms Page 18
Ridership<br />
Number of individuals using a transit line. Used as an assessment of a transit line’s<br />
attractiveness.<br />
RMSE<br />
Root Mean Square Error is a measure of total error defined as the square root of the sum<br />
of the variance and the square of the bias. It assumes that larger forecast errors are of<br />
greater importance than smaller ones; hence they are given a more than proportionate<br />
penalty.<br />
Screenline<br />
An imaginary line, usually along a physical barrier such as a river or railroad tracks,<br />
splitting the study area into parts. Traffic counts and possibly interviews are conducted<br />
along this line, and the crossings are compared to those calculated from the home<br />
interview data as a check of survey accuracy. Crossing may also be compared with<br />
model estimates as part of calibration.<br />
Selected Link Analysis<br />
Traces the entire length of each trip passing through a particular link or set of links along<br />
the network to determine where such trips are coming from and going to.<br />
Selected Zone Analysis<br />
Traces the entire length of each trip traveling to or from a particular zone or set of zones.<br />
Shortest Path<br />
A path representing the least cost option of traveling between any specific origin and<br />
destination pair.<br />
Socioeconomic Data<br />
Demographic data, such as household, population, and employment characteristics, that<br />
are input into the model to determine the impact on trip-making patterns.<br />
SOV Trips<br />
Single Occupancy Vehicle trips, or drive-alone trips, represent the number of trips with<br />
only one person in the vehicle, including the driver.<br />
Special Generators<br />
Concentrations of activities of such size or unusual nature to warrant special<br />
consideration in trip generation analysis.<br />
Station<br />
A node in the transit network that offers an opportunity for automobile access.<br />
Stop Node<br />

<strong>FSUTMS</strong> <strong>Comprehensive</strong> <strong>Modeling</strong> <strong>Workshop</strong>– Glossary of Terms Page 19
Study Area Boundary<br />
The area that is expected to take on urban characteristics in the next 20 to 30 years (by<br />
the end of the planning period).<br />
TAZ<br />
Traffic Analysis Zone - a small geographic area that serves as the primary unit of analysis<br />
in a travel forecasting model.<br />
Traffic Count<br />
The observed number of trips collected at a specific location. Used to assist with model<br />
validation.<br />
Transit Legs<br />
Distinct units of a transit line representing a segment from one stop to the next. Transit<br />
paths are built by assessing the relative costs of available transit legs.<br />
Transit Line<br />
A collection of transit stops arranged into a route along which public transport vehicles<br />
travel. A system of interacting transit lines is a transit network<br />
Transportation Model<br />
A mathematical description of a transportation system’s characteristics including traffic<br />
volumes, land use, roadway type and population. After a mathematical relationship is<br />
established, the model is used to predict traffic volumes based on anticipated changes in<br />
the other characteristics.<br />
Trip Assignment<br />
The process of determining route or routes of travel and allocating the zone-to-zone trips<br />
to these routes.<br />
Trip Distribution<br />
The process by which the movement of trips between zones is estimated. The data for<br />
each distribution may be measured or estimated by a growth factor process, or by<br />
synthetic model.<br />
Trip End<br />
Either a trip origin or a trip destination.<br />
Trip Generation<br />
A general term describing the analysis and application of the relationships that exist<br />
among the trip makers, the urban area, and trip making. It is used to determine the<br />
number of trip ends in any part of the urban area.<br />
Trip Purpose<br />
The reason for making a trip, normally one of several possible purposes. Each trip may<br />
have a purpose at each end; (e.g., home to work) or may be classified by the purpose at<br />
the non-home end (e.g. home to shop).<br />
<strong>FSUTMS</strong> <strong>Comprehensive</strong> <strong>Modeling</strong> <strong>Workshop</strong>– Glossary of Terms Page 20
Trip Table<br />
A table showing trips between zones -- either directionally or total two-way. The trips may<br />
be separated by mode, by purpose, by time period, by vehicle type, or other classification.<br />
Trip Rate<br />
The average number of trips per household for specific trip purposes. In Florida, trip<br />
rates are usually applied by household size and auto availability within each zone by trip<br />
purpose.<br />
Validation<br />
The procedure used to adjust models to simulate base year traffic conditions. A<br />
preliminary step that must be undertaken before models may be reasonably used to<br />
forecast future traffic conditions.<br />
VHT<br />
Vehicle hours of travel.<br />
VMT<br />
Vehicle miles of travel.<br />
Volume-to-Capacity Ratio<br />
The number of trips simulated in the model divided by the capacity of the link. A<br />
volume-to-capacity ratio of 1.0 represents 100 percent of the capacity.<br />
Volume-to-Count Ratio<br />
The number of trips simulated in the model divided by the count on the link. A<br />
volume-to-count ratio of 1.0 represents an exact match between the simulated volumes<br />
and the observed counts. Typically assessed only during validation.<br />

What is <strong>FSUTMS</strong>?<br />
►Florida<br />
Standard<br />
Urban<br />
Transportation<br />
Model<br />
Structure, , is a computerized transportation<br />
modeling package developed by the Florida<br />
Department of Transportation and used by all 26<br />
Metropolitan Planning Organizations (MPO), FDOT<br />
Districts, and other planning agencies in Florida.<br />
►This process provides planners with the capability<br />
to efficiently and economically perform analyses of<br />
multi-modal modal transportation systems for many<br />
planning applications.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

What is <strong>FSUTMS</strong>? (Cont.)<br />
► The first <strong>FSUTMS</strong>, , begun in 1978, was built around a set<br />
of mainframe programs called Urban Transportation<br />
Planning System (UTPS), distributed by the Federal<br />
Highway Administration and the Urban Mass Transit<br />
Administration (FHWA/UMTA).<br />
► The second <strong>FSUTMS</strong>, , begun in 1985, was built as a<br />
framework around Tranplan, , a family of urban<br />
transportation planning and related software tools,<br />
distributed by Urban Analysis Group and later Citilabs.<br />
► The current <strong>FSUTMS</strong> is powered by Cube, , a family of<br />
urban transportation planning and related GIS software<br />
tools, distributed by Citilabs.<br />

Understanding Cube<br />
► A major difference with Cube from other systems is that<br />
‘all’ of the model (the models themselves, the graphical<br />
workspaces, the scenarios, and the data and results for<br />
the scenarios) are all linked within one overall file called<br />
the ‘Catalog’.<br />
► A model user who wishes to open the model need only<br />
remember the name of their catalog.<br />
► Once the Catalog is selected and opened in Cube, Cube<br />
provides three ‘windows’ for developing and working with<br />
the model.<br />
► The screen image provided on the next slide shows the<br />
three windows.<br />

Trip Generation<br />
Trip Generation is a process in transportation demand<br />
modeling that predicts decisions to make trips for<br />
specified purposes based on the characteristics of both<br />
land use and trip makers.<br />
During this step, trip-making ability is predicted based on the characteristics of<br />
the activity and some measure of transportation service to or from a section of<br />
the study area.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
3<br />
Trip Purposes<br />
►In general, trip generation models are used to<br />
predict the number of trips within geographical<br />
subareas (zones), usually on a daily basis and for<br />
several trip purposes.<br />
►The number of purposes may vary from one urban<br />
area to another, depending on the complexity of the<br />
model.<br />
►The purposes are, at a minimum, divided into<br />
home-based work, home-based<br />
nonwork and<br />
nonhome-based trips.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

►Purpose 7 – External-Internal<br />
►Purpose 8 – External-External<br />
Person Trips<br />
Vehicle Trips<br />
Note: Some of the models have expanded the trip purposes to include airport,<br />
special tourist sites, school and breakdown of trucks.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

Trips and Trip Ends<br />
► An important concept in trip generation is the distinction<br />
between trips and trip ends.<br />
► Trip generation models estimate trip ends by traffic zone,<br />
not trips upon the travel network.<br />
► Later in the process, the trip distribution model develops<br />
trips by matching together pairs from each of the two<br />
classes of trip ends.<br />
Production<br />
- The home end of a home-based trip or the<br />
origin of a non-home<br />
home-based trip.<br />
Attraction<br />
- The non-home end of a home-based trip or<br />
the destination of a non-home<br />
home-based trip.<br />

Socioeconomic Input Data Requirements<br />
►Socioeconomic data such as number of dwelling<br />
units, school enrollment, and number of employees<br />
are needed as input.<br />
►Once a study area is defined, it must be divided into<br />
small geographical “units. units.” These units are called<br />
traffic analysis zones, or TAZs.<br />

►<br />
►<br />
Traffic Analysis Zones are geographic areas<br />
dividing the planning region into relatively<br />
similar areas of land use and land activity<br />
zones. Zones are used to connect land use<br />
values to transportation networks. Zones<br />
represent the origins and destinations of travel<br />
activity within the region, and serve as the<br />
primary unit of analysis in a travel forecasting<br />
model. Zone numbers typically begin with one<br />
and are consecutive, although this is no longer<br />
a requirement of the software.<br />
Centroids are used to identify the center of<br />
activity within a zone and connect that zone to<br />
the facilities or links.<br />
Nodes represent a point where two links join in<br />
a network, usually representing a decision<br />
point for route choice, but sometimes indicating<br />
only a change in an important link attribute.<br />
Nodes that are not centroids (zones) can begin<br />
with any non-zero number and need not be<br />
consecutive.<br />

Sources of Zonal Data<br />
► The primary source of the household data is the U.S. Census.<br />
The Census publishes STF3A files, which are a reliable source<br />
for information on population and dwelling units composition<br />
including auto availability and vacancy status.<br />
► The Census Transportation Planning Package (CTPP) is<br />
another good source for auto availability.<br />
► Hotel and Motel information can be obtained through the DBPR<br />
Hotel/Motel Division or local chambers of commerce.<br />
► Local planning departments are a good source of many of the<br />
required variables, such as parcel data, development orders,<br />
future land use maps, and utility hookups<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

Sources of Zonal Data (cont’d)<br />
► In 2007, FDOT purchased private employment data from<br />
InfoUSA for the entire state of Florida.<br />
► Employment data used in the zonedata has been<br />
traditionally obtained through the Florida Agency for<br />
Workforce Innovation (AWI).<br />
► The FDOT Policy Planning Office in Tallahassee has<br />
access to the AWI records through a confidential<br />
employer number-matching matching program.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

Sources of Zonal Data (cont’d)<br />
► Other sources of employment data include:<br />
Longitudinal Employment and Household Dynamics<br />
(LEHD)<br />
Bureau of Economic and Business Research (BEBR) at<br />
the University of Florida<br />
Local Chambers of Commerce<br />
Dun and Bradstreet (Base Year)<br />
Woods and Poole (Forecast Year)<br />
► Public school enrollment data can be obtained from the<br />
local school board or the Florida Department of<br />
Education (DOE).<br />
► Private schools need to be contacted individually. The<br />
DOE has some data on private schools.<br />

Special Generators<br />
► Special generators may be required when normal<br />
generation equations produce too much or too few<br />
productions or attractions than expected for a trip<br />
purpose for a particular TAZ.<br />
► Adjustments may be necessary if the trip generation<br />
rates applied to the socioeconomic data do not produce<br />
the correct number of trip ends.<br />
For example: parks and beaches normally have few<br />
workers and would produce very few attractions based<br />
on employment … By computing a value for the TAZ<br />
from some other source, the planner can correctly<br />
estimate attractions for HBSR trips.<br />

Developing Trip Rates<br />
► Trip rates are developed from Travel Characteristics /<br />
Household Surveys.<br />
► The data for these surveys is obtained through<br />
telephone interviews or mail-back surveys with<br />
members of selected dwelling units.<br />
► Members of the household are asked to keep a trip<br />
diary or log of all trips during a 24-hour period or longer.<br />
► The surveys are continued until sufficient data is<br />
obtained for each cell in the matrix to meet the required<br />
statistical analysis for sampling.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
33<br />
Trip Production Matrix Rates<br />
►Rates are in person trips and are collected by<br />
purpose.<br />
►Transient dwelling units (hotel-motel units) are<br />
assumed to have one auto per occupied room.<br />
►Rates can be calculated by other classifications<br />
such as retired, and working families with children<br />
and without children.<br />

External Process<br />
► The External Process is used to produce an external to<br />
external trip table for a study area. These are trips that pass<br />
through the urban area and do not stop.<br />
► Each urban area has developed an existing table of external to<br />
external trips for the study area. The tables were generally<br />
developed from surveys conducted at the external stations.<br />
► The external process takes the existing table in a DBF format<br />
and builds a trip table matrix that can be read by Cube.<br />
► The existing trip table can be expanded by a Fratar Program to<br />
match the expected growth at the external stations.<br />
► Alternatively future year EETRIPS can be entered manually<br />
through application of spreadsheets and trend data.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
65<br />
External Travel Surveys<br />
►External Travel Surveys are conducted to<br />
understand the travel behavior of trips entering<br />
and/or leaving the study area.<br />
►Questions are asked of drivers to understand where<br />
the driver is coming from, where the driver is going<br />
to, and why the driver is making the trip.<br />
►These surveys are necessary to develop EE trip<br />
origin and destination (O&D) matrices and EE/IE<br />
trip splits.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

External Travel Surveys Methods<br />
►Vehicle Intercept<br />
Requires pulling over vehicles and asking the<br />
drivers about the trips that they are making;<br />
cooperation from law enforcement is necessary<br />
This type of survey is generally more robust than<br />
other methods<br />
Benefits include high response rates and a high<br />
degree of control over the sampling method<br />
No longer permitted in Florida<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
67<br />
External Travel Surveys Methods (Cont’d)<br />
►Rest Stop Intercept<br />
Requires approaching drivers who have stopped at<br />
a rest stop<br />
If the rest stop is privately owned, the cooperation<br />
of the owner will be needed to conduct the survey;<br />
this cooperation may be difficult to acquire and may<br />
impose limits to the sampling method<br />
High degree of self selection bias dependent on the<br />
driver’s s desire to stop at that location<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
68<br />
4-34
External Travel Surveys Methods (Cont’d)<br />
►Video Mail-Back<br />
Requires setting up cameras to capture images of<br />
vehicle license plates and cross-checking checking against<br />
DMV records, then mailing surveys to the drivers<br />
and waiting for a response<br />
Unreliable response rates<br />
Limits in video technology may make it difficult to<br />
accurately identify license plates<br />
Inter-agency cooperation is required in order to<br />
acquire DMV records<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
69<br />
External Travel Surveys Methods (Cont’d)<br />
►Video Coordination<br />
Requires setting up cameras to capture images of<br />
vehicle license plates and coordinating the license<br />
plate images with other video captures around the<br />
perimeter of the study area<br />
Only provides information concerning EE O&D and<br />
EE/IE split; trip purpose information is not revealed<br />
Limits in video technology can make it difficult to<br />

Overview<br />
► The highway network model combines network attributes<br />
in a series of files and generates an unloaded network<br />
for use in subsequent model steps.<br />
► A network is a representation of an existing or proposed<br />
highway and/or transit system in a format that the<br />
computer can process for network-based travel demand<br />
modeling.<br />
► A highway network is a system of links and nodes that<br />
describes an area's roadway system. Nodes are points<br />
in the network where features intersect, end, or curve<br />
sharply. A link represents the section of a transportation<br />
network that is between two adjacent nodes.<br />

Zone Network Compatibility<br />
►Connect zones to the lowest level of facility<br />
included in the network.<br />
►Connect zones based on actual access locations<br />
such as local streets and major driveways (If<br />
multiple access points exist along a corridor, use a<br />
mid-point).<br />
►Zone Centroids should not connect to four-legged<br />
intersections.<br />
►Individual zones should not typically generate more<br />
than 15,000 person trips in the base and future<br />
year.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
6<br />
5-3
Zone Network Compatibility (Cont’d)<br />
► Avoid bisecting zones with highway network links;<br />
freeways, arterials and collectors should form zone<br />
boundaries.<br />
► Other considerations in delineating zone boundaries<br />
include physical features (e.g., rivers, bays), political<br />
boundaries (e.g., city limits), census geography, land use<br />
considerations (e.g., to separate special generators, to<br />
achieve land use uniformity), and transit access.<br />
► For more information on delineating zone boundaries,<br />
please refer to the white paper titled “A A Recommended<br />
Approach to Delineating Traffic Analysis Zones in<br />
Florida”, , FDOT Systems Planning, September 2007.<br />

Model Structure and Procedures<br />
►The Highway Network Model is built during the<br />
second step in the model.<br />
►The model will first read the input files to include<br />
highway network files, turn penalty/prohibitors<br />
prohibitors,<br />
speed/capacity lookup tables, and variable factors.<br />
►The process produces a network and reformatted<br />
speed/capacity and variable factors tables.<br />
►The network can be displayed by opening a file in<br />
Cube by clicking on the model flow chart.<br />

Sources of GIS Databases<br />
► GIS databases can be used to enhance model highway<br />
networks.<br />
► The Florida Department of Transportation has purchased<br />
GIS Mapping Files (GIS Street Data Bases) for the entire<br />
state. The files are supplied by TeleAtlas/GDT.<br />
► GEOPLAN Files are now downloadable and free from<br />
the University of Florida. The files contain over 300 GIS<br />
layers of information on each county in Florida.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
9<br />
Highway Network Input/Output Files<br />
► The Highway Network Model requires the following input<br />
files:<br />
spdcap_yya.dbf<br />
~ speed/capacity lookup tables<br />
turn_yya.pen<br />
~ turn penalties and prohibitors<br />
tolllink_yya.dat<br />
~ toll link and toll plaza information<br />
vfactors.csv<br />
~ variable factors file<br />
► The Highway Network Model will generate the following<br />
output file:<br />
unloaded.ayy.net<br />
~ unloaded network database<br />
Note: Though the vfactors file is used as an input for updating the network, the<br />
information it contains is used specifically during highway assignment. As such, the<br />
vfactors file is discussed in greater detail in Lesson 9: Assignment.<br />

Network Coding<br />
► In a typical urbanized area, network link characteristics<br />
are built or refined during the model calibration or model<br />
update process.<br />
► Refinements are typically based upon local area<br />
knowledge, recent Transportation Improvement<br />
Programs (TIPs(<br />
TIPs), and FDOT’s Roadway Characteristics<br />
Inventory (RCI) database.<br />
► Districts and MPOs are encouraged to develop network<br />
data from an updated GIS database for better<br />
geographic accuracy.<br />
► Florida standard two-digit area types and facility types<br />
should be used during network coding.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
11<br />
Key Link Characteristics<br />
► Area Type (AT) – land uses surrounding roadway<br />
► Facility Type (FT) – categories of roadway types<br />
► Number of Lanes (NL) – through lanes by direction<br />
Note: These characteristics are used to assign speeds and capacities to each network<br />
link in most Florida models.<br />

Screenlines/Cutlines<br />
► Screenlines - Screenlines follow natural barriers such as rivers<br />
or man-made made barriers such as railroads.<br />
► Cutlines - Cutlines are lines drawn on a map to represent<br />
corridors, etc<br />
► Cordon Lines - Cordon lines are circular or semi-circular<br />
screenlines and may encompass an entire model region or<br />
subareas within the model.<br />
► Screenlines, Cutlines, , and Cordon lines are analyzed in the<br />
same manner.<br />
► Traffic Counts are added to all links crossing the screenlines,<br />

Traffic Counts<br />
► Traffic counts represent the number of vehicles moving<br />
along a link between an “ANODE” and “BNODE”<br />
► Traffic counts are taken from FDOT, city and county<br />
records and/or are collected for the study<br />
► FDOT Traffic counts are adjusted to represent peak<br />
season weekday average daily traffic (PSWADT) for the<br />
study area before they are added to the link records<br />
► The peak season counts are the 13 highest<br />
consecutive weeks of traffic counts at permanent count<br />
stations within the study area<br />

Overview<br />
►The highway network path-building model is<br />
designed to use the unloaded highway network<br />
information to calculate matrices of travel times and<br />
distances between each pair of traffic analysis<br />
zones in the network.<br />
►These time and distance matrices (called “skims”)<br />
are accumulated over the shortest highway paths<br />
based on link lengths and uncongested (free-flow)<br />
flow)<br />
travel speeds coded within the highway network<br />
database.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
67<br />
What is the Purpose?<br />
► Minimum Paths identify the driving time (from anode to<br />
bnode) ) along a path to determine the total driving time<br />
required to traverse the path between each pair of zones<br />
in the network.<br />
► The process also updates the minimum time paths with<br />
any time penalties and tolls, as well as terminal times<br />
and intrazonal times.<br />
► Then the process skims the minimum time path and<br />
outputs a matrix of accumulated times between each<br />
pair of zones.<br />
► Travel times are used as a basis for the trip distribution<br />
step.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

► The Highway Path Model will generate the following<br />

Penalties/Prohibitors<br />
Prohibitors<br />
►Time Penalties are values of time that can be<br />
added to a link such as:<br />
Bridge Bridge Links (most common application)<br />
HOV Access Links<br />
►Turn Prohibitors are applied to prevent the<br />
model from allowing a turn that is not permitted<br />
Prohibited Left Turns<br />
Directional Ramps<br />
Continuous Medians on Arterial Streets<br />

Toll Model<br />
► Toll procedures are used in <strong>FSUTMS</strong> models where toll<br />
facilities are present.<br />
► The coefficient of toll (CTOLL) is adjusted in the<br />
scenario manager.<br />
► At this point, the <strong>FSUTMS</strong> Standards do not include<br />
anything different from the original Toll Facilities Model.<br />
► The toll procedures require the following:<br />
Modification of highway network to identify toll links.<br />
Creation or modification of tolllink data file with<br />
ANODE/BNODE and toll input data.<br />

CTOLL is the constant time value of<br />
toll, with typical values ranging<br />
between 0.03 and 0.05 hours per<br />
dollar.<br />
CTOLL = ( 1 / Wage Rate) * A<br />
Where A is the proportion relevant to<br />
route choice. This value of time<br />
derived from mode choice studies is<br />
equal to about 30-40 % of the average<br />
wage rate.<br />

Note: Toll class is an identification number for an ANODE-<br />
BNODE pair. This number must be placed on the network in<br />
the toll field. Consecutive numbers are recommended. This<br />
is done automatically in the Highway Network step of<br />
Olympus and other models.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

5-38
Implementation of Toll Procedure<br />
►Current <strong>FSUTMS</strong> Cube models with toll modeling<br />
capabilities read the TOLLLINK file and append the<br />
cost and service time attributes to the highway<br />
network as link attributes.<br />
►The impact of tolls to highway skims are calculated<br />
directly from the link attributes during the highway<br />
network phase of the model.<br />
►Typically, there are no specific adjustments needed<br />
to activate toll modeling.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
77<br />
Highway Path Process<br />
►Highway Path process skims the minimum time<br />
path and outputs a matrix of accumulated times<br />
between each pair of zones called<br />
Freeskim_ayy.mat.<br />
►As indicated earlier the minimum time includes the<br />
in – vehicle driving time plus any time penalties.<br />
►An example of the minimum path time is shown on<br />
the next two slides.<br />

Overview<br />
► The Trip Distribution model is the process by which trips<br />
originating in one zone are distributed to the other zones<br />
in the study area.<br />
► Trip distribution models generally link trip origins with trip<br />
destinations based on measures of accessibility and<br />
relative levels of activity at each destination zone.<br />
► Trip distribution is the third step in the model chain. The<br />
Florida standard model typically builds a seven-purpose<br />
trip table<br />
► The trip table contains the number of person-trips<br />
between each pair of traffic analysis zones (a number of<br />
models use different trip purpose stratifications).<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
3<br />
Overview (Cont.)<br />
► Trip Distribution requires as input files the highway skims<br />
produced by the Network/Path models, the productions<br />
and attractions produced by the Generation module, and<br />
a set of friction factors.<br />
► The free-flow flow skims were revised, or “updated” to include<br />
intrazonal and terminal times prior to being input to<br />
Distribution:<br />
Terminal Terminal time refers to the walk time required to travel<br />
from trip origin to auto and from auto to final destination.<br />
Intrazonal time is an estimate of the time required to<br />
travel within a given traffic zone when the trip origin and<br />
the trip destination are both in the same zone.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

Trip Distribution<br />
►Trip Distribution is the process by which trip<br />
productions are matched to trip attractions to create<br />
a trip table of the number of trips between each<br />
zone pair in the network.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
5<br />
Gravity Model<br />
►A mathematical model of trip destinations based on<br />
the premise that trips produced in any given TAZ<br />
will distribute themselves in accordance with the<br />
distance between TAZs and the attractions they<br />
offer<br />

►Friction Factors are:<br />
Generated from household survey data<br />
Borrowed from another study<br />
FF for work can be generated from Census<br />

Socioeconomic Correction Factors<br />
►K-Factors have been used in numerous models<br />
throughout the U.S.<br />
►Purpose is to correct for anomalies in trip<br />
distribution:<br />
Too many rural-area area trips attracted to urban core<br />
Low-income resident trips attracted to suburban<br />
office locations<br />
►Proceed with caution; use only if no other<br />
adjustment methods improve distribution<br />

Subarea Balancing<br />
►Alternative to K-FactorsK<br />
►Subareas (e.g., counties, planning districts) are<br />
identified for balancing of productions and<br />
attractions<br />
►Successfully employed in NERPM and TBRPM<br />
►Proceed with caution; not as much history as K-K<br />
factor approach<br />

Congested Skims<br />
► Not included in highway-only models<br />
► Required for nested logit mode choice models<br />
► Congested skims are simulated by running pre-mode<br />
choice and pre-highway assignment prior to transit<br />
network building process<br />
► Some models use congested skims as input to<br />
distribution for home-based work trips<br />
► Some models go one step further and compute<br />
composite skims that include weighted highway and<br />
transit travel times as input to the final trip distribution<br />

Overview<br />
► What is a transit network?<br />
A transit network is a representation of a system of<br />
existing or proposed transit facilities in a format that the<br />
computer can process for network-based travel demand<br />
modeling.<br />
A transit network represents individual transit lines in a<br />
system of links and nodes. These links and nodes define<br />
the transit line stops or stations and the intervening<br />
distances between them. Connections onto and off of<br />
the transit network are also represented in a series of<br />
pedestrian and vehicular access links.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
3<br />
Overview (cont.)<br />
►What is the difference between transit stops<br />
and transit stations?<br />
Transit stops occur ON the highway network and<br />
usually along bus routes whereas transit stations<br />
occur OFF the highway network along light rail,<br />
heavy rail, or rapid rail transit facilities.<br />
Transit stops and stations are notated by positive<br />
node numbers and non-stops are notated by<br />
negative numbers (“-”)(<br />
) in the line file.<br />

Overview (cont.)<br />
Rail station data includes information on parking<br />
lot capacity, parking costs, and walk times needed<br />
to generate auto access connectors.<br />
Olympus does not include any rail modes but rail<br />
modes can be added relatively easily.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
5<br />
Overview (cont.)<br />
► What constitutes a mode?<br />
A mode is represented by the type of transportation<br />
used. This can include walk access, automobile access,<br />
local bus, express bus, rail, etc.<br />
► What does headway mean?<br />
Headway<br />
can be defined as the interval of time between<br />
the arrivals of a vehicle of a particular route at a<br />
particular stop. For example, if a bus from Route 2<br />
leaves from a particular bus stop and 30 minutes pass<br />
before another bus from Route 2 arrives at the same<br />
stop, Route 2 is said to have a headway of 30 minutes.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

7-3
Data Requirements<br />
►Route line maps and schedules are used to code in<br />
the route line files with headway, stop, and routing<br />
information.<br />
►Stations can be identified from transit provider<br />
facility inventories for input into the stations file.<br />
►Walk access is calculated by Cube Voyager by<br />
tracing paths along the network out to a maximum<br />
cost in travel time from zones to transit stops.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
7<br />
Access<br />
► What are pedestrian and vehicular access links?<br />
Non-transit legs represent minimum cost routes,<br />
traversed by non-transit<br />
modes between zone and line<br />
(access leg), line and zone (egress(<br />
legs) ) or two lines<br />
(transfer legs).<br />
Non-transit modes include pedestrian, or walk, , and<br />
vehicular, or auto, , access links.<br />
These These access links may traverse one or more physical<br />
links.<br />
These access links are generated in the PT program and<br />
validated using the REWALK and AUTOCON third party<br />
programs to ensure that access links are logical.<br />

Access – Percent Walks<br />
►“Percent walks” estimate how much area of a zone<br />
is accessible to transit by walking<br />
Assumptions<br />
Ubiquitous access throughout zone<br />
Uniform spatial distribution of productions/attractions<br />
No environmental/topological barriers that impede<br />
walking<br />
Percent walks are necessary to avoid over-<br />

<strong>FSUTMS</strong> Standards<br />
►Model Structure and Procedures<br />
The Transit Network Model is built during the fourth<br />
step in the <strong>FSUTMS</strong> model chain.<br />
The Transit Network Model utilizes Cube Voyager’s<br />
PUBLIC TRANSPORT program.<br />
The model will first read the input files to include<br />
highway network-related related files, transit route files,<br />
transit system data, transit factors, and station data.<br />
The process outputs the appropriate transit<br />
networks.<br />

► Transit Networks<br />
Transit Transit networks are typically generated for each specific<br />
period in the model. These typically include the peak<br />
and off-peak periods.<br />
Peak period transit networks are typically designated as<br />
the “PK” network. This includes both the morning and<br />
evening peak periods.<br />
Off-peak period transit networks are typically designated<br />
as the “OP” network. This includes all time periods not<br />
included in the peak periods.<br />
Input Input transit network data no longer require separate<br />
peak and off-peak files due to headway parameters.<br />

Overview<br />
► The transit network path-building model uses the transit<br />
network information to calculate matrices of travel times,<br />
costs, and distances between each pair of traffic analysis<br />
zones in the network.<br />
► These time, cost, and distance matrices (called “skims”)<br />
are accumulated over the best path between each origin<br />
and destination pair based on link lengths and travel<br />
speeds as indicated in the transit network database.<br />
Note: Cube Voyager is also capable of performing multi-path path path building. This<br />
methodology is not endorsed in Florida due to concerns with meeting FTA<br />
criteria for transit modeling. For more information on multi-path, consult the<br />
software documentation that comes with Cube Voyager.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

Data Requirements<br />
►Public Transport Network, which is created earlier<br />
in Transit Network Model process.<br />
►Fares are provided by local transit agencies.<br />
►Average transit operating speeds can be obtained<br />
from local transit agencies.<br />
►Auto/transit speed delay studies provide the basis<br />
for determining bus speeds based on automobile<br />
speeds in the model. The most recent transit<br />
speed delay study was conducted in 2005 in<br />
Jacksonville.<br />

►Model Structure and Procedures<br />
The Transit Paths Model is built during the fourth<br />
step in the <strong>FSUTMS</strong> model chain.<br />
The Transit Paths Model utilizes Cube Voyager’s<br />
PUBLIC TRANSPORT and MATRIX programs.<br />
The model will first read the input public transport<br />
network and will then enumerate, evaluate, and<br />
skim the routes.<br />
The process outputs the appropriate skim matrices.<br />

►Generalized Cost Process<br />
Generalized Cost measures the main components<br />
of transit trips.<br />
There are three broad components of transit trips:<br />
Time (Walk (non-transit), Wait, and In-Vehicle)<br />
Inconvenience (Boardings and Transfers)<br />
Cost (Fare)<br />
Generalized Cost is usually a linear function of the<br />
components, weighted by coefficients.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
57<br />
PT Best Path Pathbuilder<br />
►Generalized Cost Process (Cont’d)<br />
The coefficients incorporate the significance of<br />
time, inconvenience, and cost in the passengers’<br />
perception and converts the components to a<br />
common unit.<br />
Generalized Cost is measured in time in the PT<br />
program.<br />

►Generalized Cost Process (Cont’d)<br />
Time Component<br />
Walk (non-transit) Time – Walking can occur at different<br />
parts of the PT journey:<br />
• At the beginning and end of a journey (between stop node and<br />
zone centroid)<br />
• When transferring services (between stop nodes)<br />
• When not using any transit mode (between origin and destination<br />
zones)<br />
Wait Time – Derived using the combined headway of<br />
services available at the boarding point and calculated<br />
from user-supplied supplied wait curves.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
59<br />

►Generalized Cost Process (Cont’d)<br />
Time Component (Cont’d)<br />
In-vehicle Time – Represents time spent in the transit<br />
vehicle for each transit leg. If the journey consists of<br />
more than one leg, the in-vehicle time represents the<br />
total of the transit legs<br />
• A leg is a segment of a transit journey along a route from one<br />
stop to the next or from stop to centroid.<br />

Inconvenience Component<br />
Boarding Penalty – Fixed penalty applied at each boarding. A<br />
boarding represents the start of a journey or an interchange. The<br />
default assumes no penalty.<br />
Transfer Penalty – Represents the inconvenience of<br />
transferring between modes and is applied at transfer locations.<br />
Transfer penalties can be applied between the same mode or<br />
between different mode combinations.<br />
Cost Component<br />
Fares – The modeling of fares includes three major components:<br />
• Consideration of fares in the Route Choice<br />
• Skimming of fares for each zone pair<br />
• Calculating and reporting of revenue<br />

Route Enumeration<br />
Identifies all potentially attractive routes and enumerates<br />
them.<br />
The principles underlying this process include:<br />
• Principle 1: The journey to move progressively from the origin to t<br />
the destination.<br />
• Principle 2: Travelers tend to select journeys that are simpler<br />
(that are direct or involve few transfers).<br />
• Principle 3: Travelers are unwilling to walk very long distances.<br />

Overview<br />
►Mode choice models represent travel decisions<br />
about which vehicular mode to use as a function of<br />
level-of<br />
of-service (LOS) characteristics of the mode<br />
and traveler and household characteristics.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
3<br />
Overview<br />
► Mode Choice is actually applied in two distinctively<br />
different ways:<br />
For<br />
Highway – Only applications, Mode Choice is simply<br />
an auto occupancy model.<br />
For MPOs with transit models, , Mode Choice determines<br />
the split among highway and transit modes of travel.<br />
► Currently, most mode choice models in Florida use<br />
<strong>FSUTMS</strong> software programs, the exception is the<br />
Northeast Florida Regional Planning Model (NERPM)<br />
which uses Cube Voyager’s s XCHOICE program.<br />

<strong>FSUTMS</strong> Standards<br />
►Model Structure and Procedures<br />
Mode Choice is the fifth step in the <strong>FSUTMS</strong> model<br />
chain.<br />
All Highway-Only Mode Choice Models use a set of<br />
parameters to convert person trips to vehicle trips<br />
and produce output summary statistics.<br />
The use of either Highway-Only auto occupancy<br />
models or Nested Logit transit mode choice models<br />
is standard for <strong>FSUTMS</strong>.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

<strong>FSUTMS</strong> Standards<br />
►Model Structure and Procedures (Cont'd)<br />
The Mode Split module accomplishes several<br />
specific tasks in building auto and transit vehicle trip<br />
tables:<br />
Performs a set of trip table manipulations<br />
Allocates trips among a variety of highway and transit<br />
modes (Nested Logit only)<br />
Applies vehicle occupancy rates (Non-Transit only)<br />
Balances and factors highway trip tables.<br />

<strong>FSUTMS</strong> Standards<br />
►Model Structure and Procedures (Cont'd)<br />
Combines all trip tables into one file.<br />
• In Non-Transit models, the typical seven-purpose person-trip<br />
table output from DISTRIBUTION is converted into a single-<br />
purpose vehicle-trip table.<br />
• In Transit models, multi-purpose vehicle-trip tables are produced<br />
which subdivide auto trips by vehicle occupancy category, and<br />
transit trips by type of transit service.<br />

Parameters are not software-<br />
specific.<br />
Mode choice parameters,<br />
constants, and coefficients<br />
can be edited in the Scenario<br />

<strong>FSUTMS</strong> Standards<br />
► What are constants and coefficients?<br />
The constant for an alternative captures the average<br />
effect on utility of all factors that are not included in the<br />
model. The utility function represents how much value is<br />
associated with choosing a mode alternative.<br />
Coefficients represent the contribution of an independent<br />
variable, such as workers or vehicle availability, towards<br />
the utility function.<br />
► Where do the constants and coefficients come from?<br />
Constants and coefficients can be developed from survey<br />
and census data but are frequently borrowed from other<br />
comparable models. Constants are sometimes adjusted<br />
during validation.<br />

<strong>FSUTMS</strong> Standards<br />
►What impact do constants and coefficients have<br />
and should they be changed by the user?<br />
Constants and coefficients can significantly change<br />
the number of transit trips and should only be<br />

Transit Mode Choice Models<br />
►Multinomial Logit Model (previously used)<br />
Multinomial Logit models split trips among a<br />
variety of auto and transit modes.<br />
Auto occupancies are an output rather than an<br />
input to logit mode choice models.<br />
Florida is discontinuing the use of Binomial (only<br />
auto and transit split) and Multinomial Logit models<br />

Transit Mode Choice Models<br />
► Nested Logit Model<br />
Computes mode choice the same as multinomial mode<br />
choice, but further disaggregates the number of trips.<br />
Nested Logit models split trips among a series of modes<br />
and submodes.<br />
Allocates trips to primary modes (transit and auto) first, and then t<br />
allocates these primary mode shares to a variety of submodes<br />
(e.g., for transit, walk vs. auto access; for auto, drive alone vs.<br />
shared ride)<br />
Auto occupancies are an output rather than an input to<br />
logit mode choice models.<br />

of-the-art practice.<br />

Transit Mode Choice Models<br />
►What are the differences between Multinomial<br />
and Nested Logit Models?<br />
The Nested Logit Model provides a more realistic<br />
modeling relationship among possible modes.<br />
The Nested Logit Model minimizes violation of the<br />
Independence of Irrelevant Alternatives (IIA).<br />
The Nested Logit Model produces more accurate<br />
forecasts than the Multinomial Model if the modes<br />
are independent from one another.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

Mode Choice Models<br />
► Transit v. Non-Transit Applications<br />
Transit mode choice models are needed when<br />
considering major transit capacity options such as fixed-<br />
guideways or Bus Rapid Transit (BRT).<br />
Highway-Only models are acceptable where transit is<br />
non-existent or limited to all-day local bus/trolley service.<br />
If a model is validated with transit, the Highway-Only<br />
application should not be used because of the<br />
fundamental difference in auto occupancy procedures.<br />
Some models have been validated with both transit and<br />
highway-only versions.<br />

Overview<br />
►Assignment is the sixth step in the model chain<br />
►Trip assignment is the process whereby trips<br />
(usually described by mode, origin, and destination)<br />
are assigned to various available paths or routes in<br />
a network according to an assignment model.<br />
<strong>FSUTMS</strong> uses the Equilibrium Highway<br />
Assignment Process.<br />

Overview – Use of Assignment Results<br />
► What are the results of trip assignment?<br />
Number of daily (24-hour) trips on each link in the network.<br />
Number of trips per period on each link in the network for a<br />
Time-of<br />
of-Day (TOD) assignment.<br />
► What are assignments used for in modeling?<br />
Network validation<br />
Development and testing of transportation system alternatives<br />
Analysis of traffic impacts<br />
Estimation of traffic forecasts for roadway design<br />
Generating volumes for use in traffic simulations<br />

Overview – Equilibrium Assignment<br />
►Equilibrium, in transportation assignments, occurs<br />
when no trip can be made by an alternate path<br />
without increasing the total travel time of all trips in<br />
the network.<br />
►Equilibrium assignments are considered multipath<br />
because the final loads are a linear combination of<br />
the all-or<br />
or-nothing loads of each iteration and the<br />
fact that each load may be assigned to a different<br />
path due to the assignment of time after each<br />
iteration.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

Overview – Equilibrium Assignment Process<br />
►A series of iterative all-or<br />
or-nothing assignments.<br />
►Adjustment of travel times reflecting delays<br />
encountered in the associated iteration.<br />
►Combining loads with previous loads to<br />
minimize the impedance of each trip.<br />
►Pre-loading<br />
is used for trip types that are<br />
considered not sensitive to congestion (such as<br />
truck trips and external-external trips).<br />

Iteration 1<br />
B<br />
► First all-or<br />
or-nothing assignment, all<br />
100 trips from A to B are assigned<br />
to the top path.<br />
► The first iteration of capacity<br />
restraint adjusts the link time on<br />
that path based upon the BPR<br />
curve and reloads the network,<br />
again using an all-or<br />
or-nothing<br />
assignment. This results in 100<br />
trips on the center path which is<br />
now the minimum path.<br />
► Program computes a combining<br />
factor using a non-linear algorithm.<br />
In this example the factor is 0.75,<br />
or .75 x 100 to center path and .25<br />
x 100 to top path.<br />

Iteration 2<br />
► Second iteration, again using an<br />
all-or<br />
or-nothing assignment, results<br />
in 100 trips on the bottom path<br />
which is now the minimum path.<br />
► Program then computes a<br />
combining factor using a non-linear<br />
algorithm. In this example the<br />
factor is 0.23, or 0.23 x 100 to<br />
bottom path. This leaves 0.77 for<br />
the other paths - 0.77 x 25 to the<br />
top path and 0.77 x 75 to the<br />
bottom path. Note that 19 + 58 +<br />
23 = 100 trips.<br />

Iteration 3<br />
► Third iteration puts all 100 trips on<br />
the links to the top path again,<br />
calculates a new factor of 0.05,<br />
assigns an additional four trips to<br />
the links of the top path and<br />
reapportions the remainder based<br />
on the results of the previous<br />
iterations.<br />
► The process stops when the factor<br />
gets close enough to zero, or the<br />
user-specified specified number of iterations<br />
is completed.<br />

► Seasonal Factors<br />
The The Monthly Seasonal Factor (MSF) is derived using<br />
the Annual Average Daily Traffic (AADT) for a location<br />
divided by the Monthly Average Daily Traffic (MADT) for<br />
a specific month at that count site.<br />
The<br />
Weekly Seasonal Factors (SF) are developed by<br />
interpolating between the monthly factors for two<br />
consecutive months.<br />
The<br />
Peak Season Conversion Factor (PSCF) is used<br />
to convert short term traffic counts to Peak Season<br />
Weekday Average Daily Traffic (PSWADT) for modeling<br />
purposes.<br />
PSWADT = Traffic Count * PSCF<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
21<br />
<strong>FSUTMS</strong> Standards (Cont'd)<br />
► MOCF<br />
Since traffic models output PSWADT, the Model Output<br />
Conversion Factor (MOCF) is based on the peak season.<br />
The peak season is the 13 consecutive weeks during which the<br />
highest weekday volumes occur.<br />
The 13 week highest weekday volume occurs when the sum of<br />
SF for those 13 weeks is the lowest.<br />
The average SF of the 13 weekly SFs during the peak season<br />
is called the MOCF.<br />
The MOCF should be used to convert PSWADT to AADT.<br />
See Adding Attributes and Calculations in Highway<br />
Networks/Paths Chapter to convert PSWADT to AADT in Cube.<br />

Overview<br />
►Transit assignment models load transit trips to the<br />
least cost route (or path) between each pair of<br />
zones.<br />
►Transit assignment loads transit trip tables to transit<br />
networks and develops a loaded transit network<br />
database.<br />
►Transit assignment is not executed when running a<br />

Public Transport Loading Function<br />
Assigns transit trips to routes between zone pairs.<br />
The attractiveness of these routes is calculated during<br />
the preceding Route Evaluation function.<br />
The Loading function can produce the following:<br />
• Loaded transit (Public Transport) network with transit and non-<br />
transit loads (this network can only be viewed, not edited, in<br />
Cube)<br />
• Loaded non-transit legs (in ASCII format)<br />
• Loaded lines (in ASCII format)<br />
• Link attributes, including loads (in DBF format)<br />

Overview<br />
► Post processing consists of reporting or adjusting output<br />
data, usually in either report or map format.<br />
► The Olympus model reports the output data at the end of<br />
each step in the <strong>FSUTMS</strong> model chain.<br />
► It is anticipated that <strong>FSUTMS</strong> standard reports and map<br />
templates will be developed and implemented. These<br />
are currently under development.<br />
► This chapter will focus on setting up your own map<br />
layouts for printing.<br />
► Future versions of Cube will interface directly with ESRI<br />
GIS providing more mapping flexibility.<br />

Examples of Map Data<br />
►Network characteristics (such as area type,<br />
facility type, and number of lanes) for use during<br />

►Loaded volumes illustrating the magnitude of trips<br />
►Traffic flow (loaded volumes by band width)<br />
illustrating the magnitude of trips<br />
►Volume-to<br />

GIS Tools<br />
► Functions<br />
Layer Alignment – Shifts and scales any layer to align<br />
with other layers.<br />
Layer coordinates are not actually changed; only the base point<br />
and scale settings are. The base point and scale settings are<br />
not saved with the file; it is stored as part of the network project<br />
file.<br />
To permanently change coordinates in a network file, use the<br />
Node Attribute Compute option to recalculate the X and Y<br />
coordinates of the whole network.<br />
The Automatic Distance Recalculation option should be<br />
disabled before recalculating the coordinates and enabled<br />
afterwards.<br />
The Distance Scale for the highway network will need to be<br />
changed after scaling the coordinates.<br />

►Functions (Cont’d)<br />
Rubber Sheeting – Stretches or compresses part<br />
of the highway network.<br />
Changes the node coordinates within the rubber sheeting<br />
box.<br />
Once saved, the changes become a permanent part of<br />
the highway network.<br />

►Functions (cont.)<br />
Network Conflation – Snaps the highway nodes to<br />
an end point of the underlying GIS line shapes so<br />
they have the same coordinates.<br />
Four ways to snap nodes:<br />
• Snap Node<br />
• Snap All Nodes<br />
• Snap All Nodes in View<br />
• Snap All Nodes in Polygon<br />

GIS Tools<br />
►Functions (Cont’d)<br />
True Shape Display – Changes the network link<br />
display to show the true shape of a link based on<br />
one or more shapes in the shape file instead of a<br />
straight line (converts stick network to curved<br />
network).<br />
Line shape database (.dbf) file must include A node and<br />
B node numbers.<br />
For links with more than one shape, the .dbf file must<br />
include a sequence field indicating the sequence of the<br />
line shapes.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
9<br />
GIS Tools<br />
► Functions (Cont’d)<br />
Build Network from Shapefile – Generates a<br />
corresponding highway network from a line shape file<br />
with automatic node numbering.<br />
The shape .dbf file must have an A node and B node field.<br />
Shapes in shape file can be treated as all one-way links or all<br />
two-way way links. Or, a field in the shape file can be used to<br />
indicate one-way and two-way way shapes.<br />
If line shapes were not digitized in the direction of travel, one-<br />
way links will be created in the wrong direction. To correct this,<br />
the Reverse Line Shape function can be used.<br />

GIS Tools<br />
►Functions (Cont’d)<br />
Reverse Line Shape – Reverses the digitized<br />
direction of a line shape to correct for directional<br />
error in one-way streets.<br />
The digitized direction of a line shape is important if the<br />
line shape file will be used to build a network or as a<br />
base for true shape display.<br />
Changes to the shape file are saved automatically and<br />
therefore cannot be undone without reversing the<br />
direction again.<br />

Selected Link and Selected Zone Analysis<br />
► Used to determine the origin and destination of trips<br />
traversing a specific link, zone, or node.<br />
► Typically used in identifying travel patterns or major<br />
movements and traffic impact analyses.<br />
► Performed during the assignment step using a<br />
PATHLOAD statement.<br />
► Outputs an additional volume set that provides the<br />
number of trips on each link that traverse the selected<br />
link, zone, or node.<br />
► Can also output a matrix of volumes for the zones that<br />
traversed the selected link, zone, or node.<br />

Scripting<br />
► Overview<br />
Voyager is a modular system with 7 modules for<br />
modeling and 1 special module for flow control<br />
(feedback).<br />
The modules can be put in any order to reflect any<br />
methodological approach to modeling.<br />
The order of the modules and the file input and output is<br />
controlled with Cube Base.<br />
Some modules have Phases which require that certain<br />
functions are located within certain phases.<br />
The scripting language used for Cube Voyager is called<br />
Cube Power Scripts (CPS).<br />
Scripts are used to run each step of the model.<br />

Scripting<br />
► Eight modules:<br />
NETWORK: : Building, comparing, and manipulating<br />
highway networks<br />
HIGHWAY: Pathbuilding, , skimming, and assignment of<br />
highway networks<br />
PT: : All Public Transport functions<br />
GENERATION: : Trip Generation<br />
DISTRIBUTION: : Trip Distribution<br />
FRATAR: : Matrix growth factoring<br />
MATRIX: : Demand modeling and matrix manipulations<br />

Scripting<br />
►General Syntax<br />
COMMAND<br />
keyword=value<br />
The COMMAND always stands alone and is followed by<br />
a white space (1 or more)<br />
The KEYWORD is always followed by ‘=‘<br />
Some KEYWORDS invoke a COMMAND<br />
Some KEYWORDS may have a subscript<br />
Example: REPORT FILEI=Y, FILEO=Y<br />
Example: PATH=TIME, MW[1]=PATHTRACE(TIME)<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

Scripting<br />
►General Syntax (Cont’d.)<br />
Continuous lines in CPS<br />
Line must finish in an operator: + - / * , = | &<br />
Example:<br />
PATH=COST,<br />
MW[3]=MI.1.TRIPS,<br />
SELECTLINK=(L=1000-1001 && L=2000-2001),<br />
SELECTGROUP=1-3,5,<br />
SELECTLINKGROUP=((GRP[1]=1 && GRP[2]=2) || (GRP[3]=1))<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

Scripting<br />
► General Syntax (Cont’d)<br />
Commenting your scripts is recommended.<br />
Use of ; starts a comment, at the beginning of a line or on<br />
a line.<br />
To comment out a block of script, use /*…*/<br />
*/<br />
Example:<br />
PATH=TIME, PENI=1,3 MW[1]=PATHTRACE(COST),MW[2]=PATHCOST<br />
; MW[1] and MW[2] could be different because penalties are used<br />
; in the path. If MW[1]=PATHTRACE(TIME,1,3),they would be the same.<br />

Lesson 12 - Traffic Impact Analysis<br />
Lesson Goals<br />
►In this lesson we will learn what traffic impact<br />
analysis is and why it is conducted.<br />
►We will discuss alternate methodologies associated<br />
with performing a traffic impact analysis.<br />
►We will also discuss sources for assumptions in a<br />
traffic impact analysis<br />

What is Traffic Impact Analysis?<br />
►Traffic impact analysis is used to measure the<br />
magnitude of a proposed development’s s anticipated<br />
burden to the community’s s transportation<br />
infrastructure.<br />
►Traffic impacts are typically measured in relation to<br />
level-of<br />
of-service (LOS).<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

Why Perform Traffic Impact Analysis?<br />
►Facilitate planning efforts<br />
►Ensure that growth does not overcome the ability of<br />
the transportation network to serve such growth<br />
►New development can severely impair the<br />
performance of the transportation network<br />
►Need to address planning considerations for both<br />
short and long range traffic mitigation strategies<br />

Why Perform Traffic Impact Analysis? (Cont’d)<br />
► Proportionate Share<br />
Formulaic assessment of a DRI’s impact to the region’s<br />
infrastructure in order to identify the amount to be paid to<br />
mitigate that impact<br />
Proportionate Fair Share is a separate designation<br />
applicable to sub-DRI developments that fail concurrency<br />
Permits the development to continue by allowing the developer<br />
an opportunity to offset the impact of the development by<br />
contributing to the improvement of the affected infrastructure<br />
All local jurisdictions were required to adopt ordinances<br />
governing the Proportionate Fair Share process by December<br />

►Developments of Regional Impact (DRI)<br />
Developments surpassing a certain threshold of<br />
intensity are considered to have a regional impact<br />
DRI thresholds for residences are established<br />
based on county population<br />
DRI thresholds for other land uses differ based on<br />
land use<br />

Internal vs External Project Trips<br />
►Internal Project Trips<br />
Have their origin and destination within zones<br />
representing the project site<br />
Stay on facilities within and designed to serve the<br />
internal needs of the project site<br />
Generally referred to in the analysis as internal<br />
capture<br />
Should be calculated using ITE methodologies<br />
Are not the focus of modeling efforts to analyze<br />
traffic impact<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

12-5
Internal vs External Project Trips (cont’d)<br />
►External Project Trips<br />
Have one trip end in a zone representing the<br />
project site and one trip end in a zone outside of the<br />
project site<br />
Travel on facilities that serve travel needs outside<br />
of the project area<br />
Can be identified by using a cordon line to select<br />
roadway segments/highway links that enter and<br />
leave the project site<br />
<strong>Modeling</strong> efforts to analyze traffic impact should<br />
focus on replicating ITE external project trips<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
11<br />
Cordon Lines<br />
►An imaginary cordon around the site intersecting all<br />
facilities entering and leaving the site will help<br />
identify the external trips.<br />
►Sum the number of trips generated by the project<br />
site traveling on each of the links intersecting the<br />
cordon in order to arrive at the total external project<br />
trips for the site.<br />
►The dashed circle on the next slide represents a<br />
cordon around a proposed development site. The<br />
arrows point to the links that intersect the cordon.<br />

Why Use Models for Traffic Impact Analysis?<br />
►Models place the impacts of the proposed<br />
development in the context of an integrated<br />
transportation network.<br />
►Traffic from the proposed site can be measured<br />
against traffic generated from developments all<br />
throughout the region covered by the model.<br />
►The distribution and assignment of trips are carried<br />
out on an integrated model network, minimizing<br />
bias that results from manual procedures.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

12-7
Why Use Models for Traffic Impact Analysis?<br />
►Reduces the level of effort involved in tracing the<br />
site’s s impact beyond the immediate area of the site<br />
►Typically, models represent MPO-adopted datasets<br />
reflecting the level of growth in the region and<br />
including the planned improvements to the<br />
transportation network.<br />
►Models provide the analyst with a grounded source<br />
of assumptions on the levels of growth occurring in<br />
the study area.<br />

travel surveys and personal trip diaries<br />
Trip rates are aggregated based on survey results into<br />
various socioeconomic categories<br />

include:<br />
• Population, dwelling units, vacancy rates, lifestyle cohorts<br />
• Income, automobile ownership<br />
• Employment, schools, unique (special) land use<br />

Land Use<br />
Typically, only three production land uses and four<br />
attraction land uses<br />
• Production - single-family dwelling, multi-family dwelling, hotel-<br />
motel units<br />
• Attraction - industrial employment, service employment,<br />
commercial employment, school enrollment<br />
Land uses are aggregated and combined into zones<br />
Aggregated zone structure and abstracted access<br />
system (centroid connectors) limits the usefulness in<br />
using models for calculating internal capture<br />

Different <strong>FSUTMS</strong> Methods<br />
►There are two general methodologies for using an<br />
<strong>FSUTMS</strong> model for a traffic impact analysis:<br />
Special Generator Method<br />
Link Volume Factor Method<br />
►Each approach has pros and cons.<br />
►Each requires a combination of ITE and <strong>FSUTMS</strong><br />
methodologies in order to conduct a traffic impact<br />
analysis.<br />
►A third method called Net Impact is unacceptable<br />
but will be discussed later in order to identify it.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
23<br />
Special Generator Method<br />
►Reasons to Use the Special Generator Method<br />
Simplifies the analysis process since the<br />
appropriate number of ITE trips interact dynamically<br />
with the background traffic generated by the model.<br />
Since special generators are a direct input for the<br />
number of trips, there is no need for the analyst to<br />
develop socio-economic data to represent the site.<br />
These trips will still need to be split into the<br />
appropriate trip purpose categories by the analyst.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
24<br />
12-12
Special Generator Method (Cont’d)<br />
►Method<br />
Calculate ITE external trip generation off-model.<br />
Input trips into the special generator file for the<br />
zone(s) ) corresponding to the development site.<br />
Allocate trip percentages into the trip purpose<br />
categories in the special generator file.<br />
Factor ITE vehicle trips to person trips<br />
Run the model.<br />
Compare ITE trips to the loaded network link<br />
volumes corresponding to the links at the site<br />
cordon.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
25<br />
Special Generator Method (Cont’d)<br />
► Method (Cont’d)<br />
Adjust the trips in the special generator file as necessary<br />
and rerun the model:<br />
Increase the number of trips if the model trip volumes at the site<br />
cordon are lower than the ITE trips.<br />
Decrease the number of trips if the model trip volumes at the site<br />
cordon are higher than the ITE trips.<br />
This may be an iterative process.<br />
Once the model volumes are greater than or equal to<br />
the ITE trips, conduct a selected zone analysis of the<br />
zone(s) ) corresponding to the development site in order to<br />
trace trips throughout the network.<br />
Take Take the results from the model and continue with the<br />
analysis using established practices.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
26<br />
12-13
Special Generator Method (Cont’d)<br />
►Caveats<br />
Will bias the trip distribution due to the uneven<br />
nature of <strong>FSUTMS</strong> and ITE trip generation<br />
methods.<br />
Sites<br />
being studied may produce or attract<br />
significantly more or fewer trips than similar land<br />
uses of similar intensity in the modeled study area.<br />
Larger models take more time to run. This can<br />
make iterating special generator trips more difficult<br />
and time consuming.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

Special Generator Method (Cont’d)<br />
► Example:<br />
A developer is<br />
planning to build a<br />
large retail super<br />
store named Big<br />
Box.<br />
This store will be<br />
located near an<br />
existing competitor<br />
named Large Lot.<br />
Both stores have<br />
similar<br />
characteristics.<br />
They each have 400<br />
employees.<br />

Special Generator Method (Cont’d)<br />
► Example (Cont’d):<br />
Large Lot is already<br />
present in the model,<br />
so Big Box would<br />
need to be added.<br />
If Big Box were<br />
coded into the model<br />
as a traditional<br />
<strong>FSUTMS</strong> land use,<br />
the corresponding<br />
TAZ would possess<br />
400 commercial<br />
employees in the<br />
zone data file.<br />
As a result, they<br />
would generate<br />
approximately the<br />
same number of<br />
trips.<br />

► Example (Cont’d):<br />
If, on the other hand,<br />
Big Box were coded<br />
using the special<br />
generator method, Big<br />
Box would have no<br />
data in the zone data<br />
file.<br />
Instead, the special<br />
generator file would be<br />
run iteratively until we<br />
reached the ITE<br />
vehicle trip value for<br />
this land use: 10,519.<br />
Even though both sites<br />
have similar<br />
characteristics, Big<br />

Link Volume Factor Method<br />
►Reasons to Use the Link Volume Factor Method<br />
Trip generation will be consistent between all zones<br />
throughout the model.<br />
Eliminates any biases in trip distribution<br />
Sites being studied will produce or attract a similar<br />
amount of trips as similar land uses of similar<br />
intensity in the modeled study area.<br />
Removes the need to conduct iterative adjustments<br />
to the model’s s trip generation, saving time and<br />
effort with larger models.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />

Link Volume Factor Method (Cont’d)<br />
► Method<br />
Estimate socioeconomic data based on developer<br />
specifications of the project. Use rates for persons per<br />
dwelling units and employees per 1,000 sq ft that are<br />
acceptable to reviewers.<br />
Input socioeconomic data representing the project into<br />
the zonal data file.<br />
Run the model.<br />
Conduct a selected zone analysis of the zone(s)<br />
corresponding to the site and save the resulting data to<br />
the loaded network. These are the project trips.<br />

12-16
Link Volume Factor Method (Cont’d)<br />
► Method (Cont’d)<br />
Identify an external cordon around the development site.<br />
Any project trip that passes through a link that intersects<br />
with the external cordon is an external project trip.<br />
Calculate the total number of external project trips.<br />
Calculate the percent distribution of external project trips<br />
by dividing the number of project trips on each link of the<br />
network by the total number of external project trips.<br />
Use Use an off-model technique to calculate the total number<br />
of ITE external project trips for the site.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
33<br />
Link Volume Factor Method (Cont’d)<br />
►Method (Cont’d)<br />
Factor the total number of ITE external project trips<br />
by the link distribution percentages calculated<br />
earlier for each link in the loaded network.<br />
Subtract the project trips (selected zone trips) from<br />
the total volume to derive the background traffic.<br />
Take the results from the model and continue with<br />
the analysis using established practices.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
34<br />
12-17
Link Volume Factor Method (Cont’d)<br />
►Caveats<br />
The final project trips after the ITE trips have been<br />
factored by the link distribution percentages are not<br />
consistent with the modeled trip generation.<br />
Resulting trip tables do not match ITE trips.<br />
Modeled capacity constraints may not be consistent<br />
with ITE project trips. This means that project<br />
traffic may not be accurately impacted by<br />
congestion during highway assignment.<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
35<br />
Link Volume Factor Method (Cont’d)<br />
►Caveats (Cont’d)<br />
Socioeconomic data must be estimated by applying<br />
rates to data typically provided by the developer.<br />
These estimates may not accurately reflect the real<br />
development pattern of the site.<br />
Also, developer-provided provided data are typically not<br />
complete from a modeling perspective, requiring<br />
the analyst to make assumptions based on existing<br />
model data.<br />

Land Use Conversion Rates for Traffic Impacts<br />
► Data for coding a site into the model may not be<br />
available in a format relevant to the model’s s structure.<br />
► Developers typically provide data on proposed<br />
developments in terms of dwelling units for residences<br />
and square footage for employment centers.<br />
► Local sources, such as MPOs, may have developed<br />
conversion rates for their areas in terms of persons per<br />
dwelling unit for residences or number of employees per<br />
square footage for commercial properties.<br />

Computing a Link Volume Factor (Cont’d)<br />
►Use the following formula to calculate the link<br />
volume factor per link using the Link Attribute<br />
Calculator in Cube:<br />
Link Volume Factor =<br />

Total External Project Trips<br />
►Once the link volume factor has been calculated, it<br />
is then possible to factor the ITE trip generation<br />
volume for the site.<br />

Communities, et al. v. Lee County Board of<br />
Commissioners Case Nos:<br />
90-2636DRI and 90-2638DRI, Jan 14, 1991<br />
DRI process requires accounting of all trips caused<br />
by development, NOT merely the net impact<br />
resulting from displacing existing trips<br />
Rationale: if all developers used the argument that<br />
trips are diverted and net impact is negligible, no<br />
developer would be responsible for mitigation<br />

Final Considerations<br />
►Internal Capture<br />
Do not solely rely on <strong>FSUTMS</strong> for internal capture.<br />
This should be calculated using ITE methodologies<br />
►MOCF<br />
Many models are estimated for peak season<br />
conditions<br />
Model volumes for background traffic should be<br />
factored by the MOCF before calculating LOS<br />
<strong>FSUTMS</strong>--CUBE MODELING TRAINING SERIES<br />
48<br />
12-24
Final Considerations (Cont’d)<br />
►Service Volumes<br />
Capacities in model are for modeling purposes only<br />
and do not reflect actual service volume capacities<br />
FDOT Q/LOS Handbook is an appropriate source<br />
for generalized LOS volumes; however, most local<br />
governments use detailed LOS calculations<br />
Impact can be assessed using model outputs<br />
The model itself does not assess impact<br />

► This exercise will demonstrate the use of an <strong>FSUTMS</strong><br />
model as it relates to a traffic impact analysis.<br />
► This exercise will consist of adding three new TAZs to<br />
the model with a supporting roadway system. These<br />
TAZs will represent the development of an apartment<br />
complex, an office park, and a shopping center.<br />
► Once the TAZs with their accompanying data and<br />
supporting network are added to the model, we will run<br />
the model and conduct a selected zone analysis to<br />
measure the impact to the study area.<br />

Calculate Link Distribution Percentages (Cont’d)<br />
Exercise 12.1.1<br />
► Next, we will need to total our project external trips.<br />
► Imagine a cordon line surrounding the site. Click on the four<br />
links intersecting the cordon line indicated on the next slide.<br />
► You will need to manually total the volumes found in the<br />
DRI_TRIPS attribute. Please remember to total the volume in<br />
both directions and for all four links.<br />
► For this example the total project external trips is equal to<br />
9032.32. . Due to slight differences in how you edited your<br />
network, you may arrive at a slightly different number, but the<br />
value should be similar to this. If you find that your total project<br />
external trips deviates by more than a couple of hundred trips,<br />
perhaps you made an error in your calculations or in your<br />
socio-economic data.<br />

Calculate Link Distribution Percentages (Cont’d)<br />
► We will now need to add two more numeric link attributes: PCT_DIST<br />
and ITE_TRIPS. . We will also need to assume that after a thorough<br />
analysis of the ITE trip generation for this DRI that the project t external<br />
trips based on ITE rates is 14,845.<br />
1. After the new attributes have been added, select Compute from the<br />
Link drop down menu.<br />
2. Add the following equations to the Link Attribute Calculation window.<br />
3. Now click Apply.<br />
4. Click Close.<br />
PCT_DIST=DRI_TRIPS/9032.32<br />
ITE_TRIPS=PCT_DIST*14845<br />

Calculate Link Distribution Percentages (Cont’d)<br />
►We now have link distribution percentages for our<br />
project external trips on our loaded network.<br />
Furthermore, we have applied our ITE generated<br />
trips to these percentages.<br />
►From here you would continue on with your traffic<br />
impact study using appropriate practices.<br />
