On a segment of A1 motorway in Casablanca, Morocco, traffic flow data was collected. The measured maximum flow was 1750veh/h for one lane when the averge spacing was 26.3 m/veh. We are assuming that speed and density are linearly related. Obtain the critical density and speed values to show them on the speed-density, density-flow and speed-flow equations. Please also obtain the speed and density values when the flow is 850 veh/h during rush hour

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.
