Abstract
A process for monitoring traffic for automatic vehicle incident detection using radar waves to detect the vehicles, their instantaneous speed and their distance. The process consists in correlating the information obtained regarding vehicles in one and the same distance bracket during two consecutive processing time intervals, so as to determine, at each instant, the acceleration of each vehicle and a prediction of its speed, and in then detecting an incident in a distance bracket by detecting the passing of the speed of a vehicle below a given speed threshold. The advantages of the process resides in rapid incident detection in regard to a road or motorway network, with a view to informing the users rapidly.
