ABSTRACT:
Proximity radar mounted in a vehicle determines the location of other vehicles. Other vehicles detect their own positions and broadcast those positions to all surrounding vehicles. Vehicle position data is plotted on a moving map so the driver can see the location of other vehicles, in some cases with an icon color which matches vehicle color(s). A driver can open a communication link with drivers who are projected to constitute a collision threat. A fixed radar unit can be positioned at blind intersections and broadcast vehicle location information for vehicles not equipped with the ability to track their own locations.
