Abstract:
1. A system for reducing the likelihood of collision between a first vehicle and a second vehicle in an intersection, the first vehicle including a first device for receiving global positioning system (GPS) signals, generating at least one of a first time, position and velocity signal based on the received GPS signals, generating at least one of a second time, position and velocity signal based upon the motion of the first vehicle, comparing the first and second signals, generating a corrected first vehicle signal, and transmitting the corrected first vehicle signal, the second vehicle including a second device for receiving GPS signals, generating at least one of a third time, position and velocity based on the received GPS signals, generating at least one of a fourth time, position and velocity based on the motion of the second vehicle, comparing the third and fourth signals, generating a corrected second vehicle signal, a traffic flow controller for controlling traffic flow through the intersection, the traffic flow controller receiving the corrected first vehicle signal and corrected second vehicle signal, calculating from the corrected first vehicle signal and corrected second vehicle signal the likelihood that the positions of the first and second vehicles will coincide in the intersection, and generating a traffic flow control signal adapted to minimize the likelihood of coincidence of the first and second vehicles in the intersection.
