Abstract:
1. A method for preventing accidents between first and second vehicles at intersections, comprising: determining a position and velocity of the first vehicle, storing map data in a memory unit relating to edges of lanes of roadways including roadways that intersect at the intersection, edges of roadways including roadways that intersect at the intersection and traffic control information relevant to travel of vehicles approaching or passing through the intersection, determining a position and velocity of the second vehicle, obtaining the traffic control information as the first and second vehicles approach or pass through the intersection, predicting, using a processor, a collision between the first vehicle and the second vehicle based on the determined position and velocity of the first and second vehicles, the map data stored in the memory unit and the traffic control information, and initiating an action or changing operation by a reactive component or system in or on the first vehicle when a collision is predicted by the processor.
