Survey on VANET Based Self Adaptive Prioritized Traffic Signal Control

Abstract

Increase in the number of vehicle causes traffic congestion at intersections of roads. It suffers the people time and Emergency Vehicle (EV) such as, ambulance, fire brigade etc, are stuck or delay to destination causes heavy losses. To avoid this, Our Traffic control system should be intelligent and adaptive in Management of signal allocation, EV has to be varies with priority order to create desirable circumstances. Here, I propose to use Vehicular Ad Hoc Networks (VANET) to collect, schedule and aggregate speed and location information of individual vehicles to optimize signal control at traffic intersections. By using VANET, The location information and real-time speed of vehicles can be providing to the traffic signal controller. Current Traffic Control System Based on VANET proposed adaptive Job Scheduling to reduce the conflicts across the intersections. But not provided the Solution to minimize the time delays for Emergency Vehicles passes through intersection. In my proposed work, the Priority Scheduling Algorithm (PS) used to provide the efficient prioritize Traffic Control System. The Priority Scheduling Algorithm schedules the higher priority vehicles (that are Emergency Vehicles). The Traffic Controller Unit, which is traffic intersection control fetches the scheduled result and clears a lane of road for EV by leading all in-ranged vehicles, and control the Physical as well as Virtual Traffic Light. It continuously performs its task until EV crossed Intersection.
