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.
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.
Spot speed study definition - speed of traffic at one point or spot on a traffic way (instantaneous speed). 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;

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.
Speed Studies. CIVL 4162/6162 (Traffic Engineering) Learning Objectives. Determine following characteristics of spot speed. mean, median, mode, pace, 85th percentile, Fit a speed distribution. Check for normality. Comparison of assumed versus observed distribution. Introduction. Speed data is needed for a variety of traffic analyses.
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.
