A review on intelligent intersection management methods

Intersections play a key role in reducing the congestion and road traffic and are the bottleneck of traffic on urban thoroughfares. The capacity of intersections determines the volume of vehicles passing through the entire transportation network, and it is essential to prevent any disruption to vehicle traffic, such as traffic jams and accidents. Accordingly, in this paper, the importance of the topic of intersection management is discussed. Then, a general classification of the types of intersection management methods is presented. The conventional and classic methods are based on the use of traffic lights, which applies the appropriate command to the traffic light by investigating the traffic conditions in the intersection. With the advancement of communication technologies, the method of cooperative intersection control, which works without the use of traffic lights, has been emerged. This system, not only reduces the delay in crossing the intersection but also improves the passengers’ and pedestrians’ safety.
