An Approach for Adaptive Traffic Light Control System in ITS using VANET

Traffic congestion is a common problem in everyday's life as number of vehicles is increasing day by day on the road. So, traditional road traffic control system needs to be updated accordingly. An adaptive traffic light control system can solve the traffic congestion problem efficiently. Vehicular Adhoc Network (VANET) is a common and useful application for designing an adaptive traffic light control system as a part of Intelligent Transportation System (ITS). This paper presents a literature review work on different types of traffic control systems and proposes a method for designing an adaptive traffic light control system using VANET technology. The proposed system ensures that all the vehicles pass through a road intersection point in an urban area smartly and efficiently. It also reduces traffic congestion and solves some other problems related to congestion by improving traffic flow through an intersection point in a city area.
