Traffic Volume

This document outlines the procedures for conducting a traffic volume study to collect data on vehicle and pedestrian traffic over time. It describes setting up observation points at a straight road section and intersection to count vehicle types in 15-minute intervals during peak hours. Tables are included to record the vehicle classification data by direction and movement. The discussion analyzes the traffic flow trends observed, noting higher volumes straight through the intersection likely due to nearby attractions and offices letting out. The document provides details on the objectives, equipment, procedures, and format for reporting the results of a traffic volume study.

Introduction
Traffic volume studies are conducted to collect data on the number of vehicles and/or
pedestrians that pass a point on a roadway facility during a specified time period. This
time period varies from as little as 15 minutes to as much as a year, depending on the
anticipated use of the data. The data collected may also be put into subclasses, which
may include directional movement, occupancy rates, vehicles classification and

pedestrian age. The traffic volume counts are conducted by recording observed vehicle
with a tick mark on a prepared field form or using or counter.
Theory
Identify the peak hour factor, PHF of the study
ADT =

V
V15 x 4

Where,
V

= hourly volume, in vph

V15

= volume during the peak 15 minutes of the peak hour.

Objective
The objectives are:
1. To determine the vehicle composition in the traffic flow stream
2. To observe the traffic flow trend and the movement patter
3. To estimate hourly volume and average daily traffic (ADT)

Apparatus
1. Mechanical hand tally counter
2. Stop watch
3. Field data survey form
Procedure
At a section of straight road
1. The layout of the study area is selected and sketched. The area selected is a
strategic location (safe of enumerator). Obstructed location is avoided.
2. Each enumerator concentrated on each lane and one-direction flow.

3. The volumes of the observed vehicles is recorded and determined using tally
counter according to class of vehicle in every 15 minutes for 1 hour time. The
counter is reset to the zero before resume counting.
At the intersection
1. The layout of the junction (study area) is selected and sketched. The area selected
is a strategic location (safe of enumerator).
2. Each enumerator concentrated on each lane and one-direction of flow.
3. The movement condition (through, left or right turning) are defined on the
intersection under study.
4. The volumes for each movement is recorded and determined according to class
of vehicle in every 15 minutes for 1 hour time. The counter is reset to the zero
before resume counting

Discussion
POINT 1 (FROM BANGI TO UNITEN MAIN GATE-LEFT TURN)
POINT 2 (FROM BANGI TO ROUNDABOUT-STRAIGHT AHEAD)
The table shows that the large amount of traffic is heading straight to the UNITEN main
gates roundabout. This is due to the fasting month which near to roundabout having
bazaar and also reaching the off office hour. There are 2 peaks passing through from the
BANGI and to roundabout, the first peak is at 3.40pm to 3.55pm and the second peak is
on 4.10pm to 4.25pm.
