Adaptive Traffic Signal Flow Control Using Wireless Sensor Networks

The growth and scale of vehicles today makes management of traffic a constant problem. Measures such as toll based systems with electronic smart card recognition, advance notification on traffic status and fixed time control signaling are some of the measures considered to alleviate the traffic woes of passengers. However a sizeable sum of problems still exists due to incomplete utilization of the road systems. In this paper, an approach to make the traffic signal adaptive to the dynamic traffic flow using wireless sensor network is proposed. The proposed approach is simulated in LabView software and compared with the existing fixed time control scheme. From the results obtained it is observed that the proposed approach outperforms the existing approaches.
