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.

2. A Hyundai Santa Fe travels a 1.30km levelled road from Bonifacio roundabout to City Lights Hotel in a minimum time of 45.60seconds. Given that the car accelerates and decelerates at 2.53 m/s², which starts from rest at the roundabout and coming to a stop at the Hotel, determine the maximum speed (in kph) and the time (in seconds) it travel at this speed. Assume time for acceleration and deceleration are equal.
