A section of highway is known to have a free-flow speed of 50mph and a capacity of 3600 veh/h. In a given hour, 2400 vehicles were counted at a specified point along this highway section. If the linear speed-density relationship (greensheild model) applies, what would you estimate the space-mean speed of these 2400 vehicles to be?

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.
