Claim 0:
1. A method for calculating a probability of a collision between vehicle to reduce a number of serious and fatal accidents at intersections by predicting a hazardous behavior and changing road user behavior to prevent probable consequences, comprising:
receiving a real-time trajectory data of current objects produced by multi target tracking radar sensors, wherein the trajectory data includes vehicle location and vehicle speed;
reading prior trajectory data for a particular class of vehicle and continuously comparing it with said received real-time trajectory data of the same class in order to calculate an extent of deviation and a statistical probability;
calculating a time to impact and a speed of impact for all current vehicles considering typical historic trajectories from that point onwards;
tracking of velocity and location trajectory over time for more than one intersecting path of a vehicle and relating said velocity and location trajectory to a set of prior velocity and location trajectories for a similar vehicle class of behavior in order to determine behavior of road users;
determining which response to mitigate a collision will be most appropriate for each scenario to alert a possible inattentive driver; and
actuating possible appropriate action to each scenario.
