4.9.2. Classified Traffic Volume Count Survey<br />

1. The classified traffic volume count surveys shall be carried out for 7 days<br />

(continuous, direction-wise) at the selected survey stations. The vehicle<br />

classification system as given in relevant IRC code may be followed. However,<br />

the following generalised classification system is suggested in view of the<br />

requirement of traffic demand estimates and economic analysis:<br />

Bus<br />

LCV<br />

Motorised Traffic<br />

2-Wheeler<br />

3-Wheeler<br />

Passenger Car<br />

Utility Vehicle (Jeep, Van etc.)<br />

Mini Bus<br />

Standard Bus<br />

LCV-Passenger<br />

LCV-Freight<br />

Non-Motorised Traffic<br />

Bi-Cycle<br />

Cycle-Rickshaw<br />

Animal Drawn Vehicle (ADV)<br />

Hand Cart<br />

Other Non-Motorised Vehicle<br />

Truck<br />

MCV : 2-Axle Rigid Chassis<br />

HCV : 3-Axle Rigid Chassis<br />

MAV Semi Articulated<br />

Articulated<br />

2. All results shall be presented in tabular and graphical form. The survey data<br />

shall be analyzed to bring out the hourly and daily variations. The traffic<br />

volume count per day shall be averaged to show a weekly Average Daily<br />

Traffic (ADT) by vehicle type. The Annual Average Daily Traffic (AADT) shall<br />

be worked out by applying seasonal factors.<br />

3. The Consultants shall compile the relevant traffic volume data from secondary<br />

sources also. The salient features of traffic volume characteristics shall be<br />

brought out and variations if any, from the traffic census carried out by the<br />

State PWD shall be suitably explained.<br />

4.9.3. Origin-Destination and Commodity Movements Surveys<br />

1. The Consultant shall carry out 1-day (24 hour, both directions) O-D and<br />

Commodity Movement Surveys at locations finalised in consultation with<br />

NHIDCL. These will be essentially required around congested towns to<br />

delineate ‘through traffic’. The roadside interviews shall be on random sample<br />

basis and cover all four-wheeled vehicles. The locations of the O-D survey and<br />

Commodity Movement surveys shall normally be same as for the classified<br />

traffic count stations.<br />

2. The location of origin and destination zones shall be determined in relation to<br />

each individual station and the possibility of traffic diversion to the Project
