Two straight roads intersect at chainage of 15,000 m and have external deflection angle equal to 100°. The road bend is to be designed for maximum speed of 80 kmph, maximum centrifugal ratio of 1/4 and a maximum rate of the change of acceleration of 0.3 m/sec³. The curve consists of a circular curve and two cubical parabola. Calculate: (i) the radius of circular curve (ii) length of transition curve (iii) chainage of all junction points

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.
