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.
20 sie 2023 · 3.2 Running speed. Running speed is the average speed maintained over a particular course while the vehicle is moving and is found by dividing the length of the course by the time duration the vehicle was in motion. i.e. this speed doesn’t consider the time during which the vehicle is brought to a stop, or has to wait till it has a clear road ...
Calculate Vehicle Speeds To calculate vehicle speed, use the predetermined study length and the elapsed time it took the vehicle to move through the course (as recorded on the stopwatch data form) in the following formula (Robertson 1994): V = T D 1.47, (2.2) where V = spot speed (mph), D = length (feet), and T = elapsed time (seconds). In the ...
Spot speed studies are conducted to estimate the distribution of speeds of vehicles in a stream of traffic at a particular location on a highway. The speed of a vehicle is defined as the rate of movement of the vehicle; it is usually expressed in miles per hour (mi/h) or kilometres per hour (km /h). A spot speed study is carried out by ...
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.
Spot speed: instantaneous speed of a vehicle at a specified cross-section or location. Average speed: it is the average of spot speeds of all the vehicles passing a given point on the highway. Running speed: It is the average speed maintained by a vehicle over a particular stretch of road, while the vehicle in motion.
