A Collaborative Vehicle and Roadside Infrastructure Communication Scheme for Congestion Detection and Traffic Management

In developing countries the traffic congestion and management is one of the critical issue. Due to traffic congestion huge amount of fuel and resources are wasted and also the safety of vehicles is an important issue while travelling. To address these problems recent advances in wireless technologies have given contribution to Vehicular ad-hoc networks (VANETs).VANETs offer new opportunities for better communication of inter vehicle communication and road traffic management by vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication. VANETs are capable to increase the road safety and road traffic management by using inter-vehicle communication. When the traffic congestion is dense, the vehicles spend long time on road to reach the destination. To eliminate the flow of vehicles from one direction, the need of gathering traffic information and central traffic management to distribute the traffic information globally is a concern. The proposed system contributes towards Gathering traffic information by single hop-by-hop communication, detect the traffic congestion and thereby manage the traffic congestion by disseminating the information to vehicles heading towards the congestion. The system also helps in increasing the range of Road-side Unit by using hop-by-hop communication.
