Abstract
In the design of roads and railways, straight sections of road or track are connected by curves of constant or varying radius as shown in figure 10.1. The purpose of the curves is to deflect a vehicle travelling along one of the straights safely and comfortably through the angle θ to enable it to continue its journey along the other straight. For this reason, θ is known as the deflection angle.
