Intersection collision avoidance using Wireless sensor network

In this study, we propose intersection collision avoidance system in preventing traffic crashes at typical urban intersections. The proposed intersection crash prevention system would display the crash warning messages to the drivers when crash-prone conditions are detected through the sensor system installed along intersection approaches. It would further change the traffic signal setting in real-time, if necessary. To support the service, the intersection collision avoidance system introduces reliable MAC and accurate speed measurement mechanism.
