Effect of inter-vehicle communication on rear-end collision avoidance

One of the possible uses of short-distance car-to-car wireless communication is for broadcasting brake motivation. An equation for calculating delay time for safe breaking between vehicles is developed. Delay time is used as the criteria for evaluating the inter-vehicle communication effect on rear-end collision avoidance. Simulation results show that: with high communication percentage and wide communication range, the total number of collisions in the whole system will drop significantly.
