A section of highway has a speed-flow relationship of the form q = a*u*u + b*u (a and b are coefficients to be determined). It is known that at capacity (which is 3100 veh/h) the space-mean speed of traffic is 35 km/h. Determine the speed when the flow is 1500 veh/h and the free-flow speed.

Concept explainers

Intersection Design

An intersection is a location where two or more roads or railways meet or join. The traffic movement is controlled at the intersection that depends on its design and type. It governs the operation, efficiency, speed, capacity, and safety of the highways, airways, and railways. The movement of the pedestrian causes hazards and delays at the intersection.
