Concept explainers

Capacity and Level of Service at Intersections

The term capacity is associated with transportation engineering. Capacity helps to understand how many pedestrians or vehicles can be handled by a transport facility. Level of service is also a term associated with transportation engineering. The level of service indicates the performance of the transport facility.

An observation point is set up along a straight line, with all the vehicles speeds being relatively constant speed and travelling the same distance. The following vehicle speeds were recorded (mph): 45, 50, 55, 62, 48, and 82. Determine the time mean speed and space mean speed of the sample both for the whole sample, and the sample without the 82-mph data point.
