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.
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.
Running speed study is designed to measure the speed at a specific location under the traffic and environmental conditions prevailing at the time of the study and determined between two points on a roadway.
vii. For reasonably reliable findings, the speed samples should include at least 50 matching plate numbers. Data Acquistion. DISTANCE = 300m.

Spot Speed Study Purposes: Establishing the speed zone of new or existing speed limit or enforcement practices. To determine speeds at the problem locations; to validate whether speeds are too high. For traffic operation and control; to establish speed limits. to determine safe speeds at curves.
Spot Speed Studies • Useful for: – Monitoring speed trends – Establishing traffic operation and control parameters – Establishing highway design elements – Evaluating highway capacity – Assessing highway safety – Measuring effectiveness of changes
(3) From this data an analysis program determines the time spent stopped and the speed at any time or distance. The program is thus able to calculate average speed, running speed, amount of delay, number of stops, distance and time between traffic signals, fuel consumption, and miles per gallon.
