Spot speeds are useful to study paints of congestion, for locating traffic signals, or for enforcing speed limits. Running speeds are useful to assess the traffic capacity of highways.
This document describes a laboratory activity for a Highway Engineering course involving a running speed study. Students will use a moving vehicle technique to collect travel time and delay data along a test route. The objective is to evaluate traffic movement and delays.
To conduct the Running Speed Study and evaluate the quality of traffic movement along a route and determine the traffic delays by using a moving vehicle technique 3 Apparatus
Spot speed studies are typically conducted by traffic engineers and transportation planners to help understand the behavior of drivers on a particular road segment, to evaluate the effectiveness of speed control measures, or to assess the need for new speed control measures.
This lab experiment measured the running speed along a 6.7km route using a moving vehicle technique. Data on travel times, delays, and traffic volumes were collected during trips in both the eastward and westward directions.
In this laboratory activity, a distance of 0.5 km between two points at particular location is chosen and a time for a vehicle passing through from first point to another point is recorded. The running speed is measured by dividing the distance passing through with the time taken.
At the end of the laboratory activity, students would be able to: I. Identify and used the correct method to carry out the Running Speed Study by using moving vehicle technique. II. Analyse data correctly and present it in a typical format.
