Collision prediction at intersection in sensor network environment

This paper presents several algorithms to predict collisions among vehicles at intersection, where the information about the movement of vehicles within interesting region is exchanged via sensor network and local broadcasting. We additionally propose algorithms to predict collisions at access road, which is important as well. Experiments show that these algorithms give very accurate results with about 0.5 average false warnings at access road on highway. In comparison with access road, they give relatively more false warning reports at intersection
