The rate of movement of a vehicle in distance per unit of time also known as speed. The common unit is km/hr. running speed is calculated by dividing the total distance by the total running time (only the time vehicle is in motion) for the route.
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.
The document discusses various types of traffic studies including spot speed studies. Spot speed studies are used to estimate the distribution of vehicle speeds at a particular location and are important for establishing speed limits and evaluating traffic control devices.
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.
Data collection forms help organize data for the spot speed study. Appendix G (Example Speed Study Forms) contains a sample "Vehicle Spot Speed Study" data collection sheet from the Florida DOT. 30. The speed profile for a particular road section can only be estimated by measuring individual speeds through a spot speed study.
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.
