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.
6 lis 2019 · As such, this chapter explores and details the most widely used laboratory and field techniques used to measure human performance. Performance can be thought of as the way an individual or something functions.
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 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 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. Journey speeds are useful to assess the adequacy of an existing road network as also the efficiency of the improvement measures and for cost-benefit studies of a ...
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.
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.
