System and method for determining intersection right-of-way for vehicles
First Claim
1. A method for determining right of way for a mobile unit at an intersection, the method comprising:
- collecting movement information about a plurality of mobile units approaching the intersection;
obtaining information about geometry of the intersection;
determining whether the mobile unit has right of way to enter the intersection, responsive to the movement information, the information about geometry of the intersection and a plurality of rules;
detecting whether a traffic signal at the intersection is functional; and
transmitting a right of way indication signal to the mobile unit when the traffic signal is detected to be not functioning.

Abstract
A method and system for determining right of way for a plurality of mobile units at an intersection. The method and system include collecting position and movement information about the plurality of mobile units approaching the intersection; storing a plurality of rules about right of way at the intersection; accessing information about geometry of the intersection; calculating which one or more of the plurality of the mobile units have right of way to enter the intersection, responsive to the position and movement information, the stored rules and the information about geometry of the intersection; and wirelessly transmitting right of way indication signals to one or more of the plurality of the mobile units.
