Intersections with priority control

Abstract

Intersections are of the greatest importance in highway design because of their effect on the movement and safety of vehicular traffic flow. The actual place of intersection is determined by siting and design and the act of intersection by regulation and control of the traffic movement. At an intersection a vehicle transfers from the route on which it is travelling to another route, crossing any other traffic streams which flow between it and its destination. To perform this manoeuvre a vehicle may diverge from, merge with, or cross the paths of other vehicles.
