Intersection Collision Avoidance Techniques
First Claim
1. A system for monitoring the position of a vehicle relative to an intersection, comprising:
- a positioning system arranged in the vehicle for determining the absolute position of the vehicle,a memory unit arranged in the vehicle for storing data relating to edges of at least one lane of the roadway on which the vehicle is traveling and edges of an intersecting lane at an intersection, anda processor coupled to said positioning system and said memory unit for determining when the vehicle has entered the intersection of the roadway on which the vehicle is traveling and the intersecting lane section.

Abstract
System and method for preventing accidents between first and second vehicles at intersections in which the absolute position and velocity of the first vehicle are determined, map data relating to edges of lanes of roadways, edges of roadways and the location of traffic control devices is stored in a map database and the status of the traffic control devices is provided to the first vehicle when needed. The absolute position and velocity of the second vehicle are determined and a collision between the first and second vehicles is predicted based on the position and velocity of the first and second vehicles, the map data and the status of the traffic control devices. An action or changing operation is initiated by a reactive component or system in the first and/or second vehicle when a collision is predicted.

16. A method for preventing accidents between first and second vehicles at intersections, comprising:
-
determining the absolute position and velocity of the first vehicle, storing map data in a memory unit relating to edges of lanes of roadways and edges of roadways, arranging the memory unit separate from the first and second vehicles, determining the absolute position and velocity of the second vehicle, predicting a collision between the first vehicle and the second vehicle based on the position and velocity of the first and second vehicles and the map data, and initiating an action or changing operation by a reactive component or system in the first vehicle when a collision is predicted. - View Dependent Claims (17, 18, 19, 20)
