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.

An intersection has four symmetrical approaches. The width (curb-to-curb distance) of each approach is 57 ft. If the length of the design vehicle is 19.4 ft and the design speed is 35 mph, what should be the all-red time? Group of answer choices 1.25 sec 1.75 sec 1.50 sec 2.0 sec
Recent computations at an approach to a pretimed-signalized intersection indicate that the volume-to-capacity ratio is 0.8, the saturation flow rate is 1600 veh/h, and the effective green time is 50 seconds. If the uniform delay is 11.25 seconds per vehicle, determine the arrival flow rate (in veh/h) and the cycle length.
