A car having a weight of 40 kN is moving at a certain speed around the curve. Assuming no lateral pressure between the tire and the pavement, compute for the following if the centrifugal ratio is 0.30. (a) Compute the force that will tend to pull the car away from the center of the curve. (b) If the degree of the curve is 4 degrees, determine the maximum speed that the car could move around the curve. (c) Compute for the embankment angle to be provided for this speed if the skid resistance is 0.12.

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.
