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.

Question

Derive the relationship between average headway, space mean speed, and average
spacing. Compute the space mean speed (in miles per hour) if the cars are moving at an average
headway of 3 seconds and average spacing of 50 ft.
