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.

Question

b) A curve is required to connect an entry grade of +3% and an exit grade of
+2% to satisfy a sight distance requirement of 250m. Determine the
minimum length of the curve assuming an average driver eye height and
hazard is at the level of the carriageway.
