Vehicular Intersection Management Techniques
First Claim
1. A system for preventing vehicle accidents at intersections, comprisinga first positioning system arranged in a first vehicle for determining the absolute position of a first vehicle;
- a memory unit within the first vehicle for storing data relating to edges of at least one lane of the roadway on which the vehicle may travel and the edges of at least one intersecting lane at an intersection;
a receiver arranged in the first vehicle for receiving position information about a second vehicle in an intersecting lane;
a processor coupled to said first positioning system, said receiver and said memory unit for predicting a collision between the first vehicle and the second vehicle based on the position of the first and second vehicles; and
a first reactive component or system arranged in the first vehicle and coupled to said processor, said first reactive component or system being arranged to initiate an action or change its operation if a collision is predicted.

Abstract
System for preventing vehicle accidents at intersections includes a positioning system arranged in a vehicle for determining the absolute position thereof, a memory unit within the vehicle for storing data relating to edges of at least one lane of the roadway on which the vehicle may travel and the edges of at least one intersecting lane at an intersection, a receiver arranged in the vehicle for receiving position information about another vehicle in an intersecting lane, a processor coupled to the positioning system, the receiver and the memory unit for predicting a collision between the vehicles based on the position and optionally speed thereof and optionally map data, and a reactive component or system arranged in one or both vehicles and coupled to the processor. The component or system is arranged to initiate an action or change its operation if a collision is predicted.

10. A method for preventing vehicle accidents at intersections, comprising
determining the absolute position of a first vehicle; -
storing data in the first vehicle relating to edges of at least one lane of the roadway on which the vehicle may travel and the edges of at least one intersecting lane at an intersection; receiving position information in the first vehicle about a second vehicle in an intersecting lane to the lane in which the first vehicle is traveling; predicting a collision in the first vehicle between the first vehicle and the second vehicle based on the position of the first and second vehicles; and initiating an action in the first vehicle or causing a change in the operation of the first vehicle if a collision is predicted. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method for preventing vehicle accidents at intersections, comprising:
-
monitoring the position of vehicles in the vicinity of the intersection relative to the intersection; monitoring the relative speed between the vehicles in the vicinity of the intersection; predicting collisions between the vehicles in the vicinity of the intersection in the intersection based on their position and speed; and when a collision is predicted, undertaking action to prevent the collision. - View Dependent Claims (18, 19, 20)
