ITS Modeling and Dynamic Traffic Assignment
By
Mohammed Hadi, Ph.D., PE
Florida International University
Presented at the Advanced Traffic Assignment Meeting
November 7, 2011

14
Background
• Need to assess the benefits and costs of ITS for
operations and planning in Florida
• FITSEVAL developed in 2007-2008
• Funded by FDOT Research Center
• A joint FDOT System Planning Office and FDOT ITS Section
effort
• Based on static assignment and analytical models
• Being extended to include DTA and analysis based on
real-world data

15
FITSEVAL Overview
• A tool developed as part of the FSUTMS environment
• FSUTMS is the approved demand modeling environment in Florida
• No need for file conversion
• Use calibrated regional models
• Flexible and extendable evaluation environment
• Up-to-date methods and parameters
• Powerful data management, modeling, and interfaces

16
FITSEVAL Utilization
• FITSEVAL can support FDOT and MPO decisions
• Benefits of ITS versus other alternatives such as geometry
improvements as part of the long range and short range plans
• It can also be used to assess ITS agency operation benefits
• The original FITSEVAL is a sketch planning evaluation
tool but has some advanced modeling capabilities
• For example it utilizes queuing theory and allow the users to
enter the incident management attributes in the region
• More detailed operational and data analysis being
introduced for design and operation purposes

17
Evaluated ITS Deployment
• Ramp Metering
• Incident Management Systems
• Highway Advisory Radio (HAR) and Dynamic Message Signs (DMS)
• Advanced Travel Information Systems
• Managed Lanes (HOT and tool lanes)
• Smart Work Zones
• Road Weather Information Systems
• Signal Control
• Transit Vehicle Signal Priority
• Emergency Vehicle Signal Priority
• Monitoring and Management of Fixed Route Transit
• Transit Information Systems
• Transit Security Systems
• Transit Electronic Payment Systems

18
Performance Measures
• Vehicle miles of travel (VMT)
• Vehicle hours of travel (VHT)
• Average speed
• Number of accidents
• Fatality
• Injury
• Property damage only
• Fuel consumption (gallons)
• Monetary benefits to users and/or agency, as appropriate
• Emission (gm)
• Hydrocarbon
• Carbon monoxide
• Oxides of nitrogen

19
Evaluation Methods
• A method developed for each component based on
review and assessment of methods used in the past
• Default ITS impact parameters derived based on a
review of previous evaluation studies, USDOT benefit
database and the values used in existing ITS planning
tools
• Costs were obtained based on surveys of agencies in
Florida
• The user can change the default ITS impact
parameters and perform sensitivity analysis

Original Development Status
• Project completed in December 2008
• Presentations, webinars, and four day workshop
completed. A second workshop planned for 2012
• Integrated with the SERPM model – the largest model
in Florida
• Integration with other regional models is being
automated by FDOT

23
Recent Application
• FDOT D4 required B/C analysis for information
sharing with FHP and arterial DMS
• Other components of FDOT D4 had already been evaluated
• The two components were not originally coded in
FITSEVAL
• The tool was easily modified to allow the evaluation
• Additional information of the use of information was gathered
from FHP
• The tool allowed very effective and efficient evaluation

24
Extended FITSEVAL
• On-going effort
• Utilization of archived data combined with
simulation/DTA to estimate the performance of the
transportation systems with and without ITS
• Extension initially only applied Freeway ITS modules
• Inclusion of EPA MOVE model parameters for environmental
impact estimations
• Expected completion: Summer 2012

25
Data Capture Tool
• ITSDCAP – ITS Data Capture and Performance
Management Tool
• Capture, archive, and analyze data from multiple sources
• Provide support of FITSEVAL and model calibration and
validation
• Estimate parameters based on ITS data
• Incident management parameters
• Managed lane parameters
• Ramp metering benefits
• Work zone and weather impacts
• DMS benefits

26
Data from Multiple Sources
• SunGuide data (TSS, TVT data, incident, DMS, etc.)
• Central data warehouse
• Statistics office data
• Weather data D4 RWIS, road weather agencies
• Managed lane dynamic congestion pricing rates
• Work zones
• Crash data/CAR System
• 511 data

27
DTA/Simulation Support
• Currently investigating replacing static assignment
with Dynamic Traffic assignment in some ITS
applications
• Allows more detailed analysis and decision support of
traffic operations
