Abstract
A system for reducing the likelihood of collision between a first vehicle and a second vehicle. Each vehicle includes a device for receiving global positioning system (GPS) signals, generating at least one of a time, position and velocity signal based on the received GPS signals, generating at least one of a time, position and velocity signal based upon the motion of the vehicle, comparing the received and generated signals, generating a corrected vehicle signal, and transmitting the corrected vehicle signal. A transportation network generates transportation network data including at least one of: network capacity data, network layout data, and network traffic data. The second vehicle'"'"'s device stores the transportation network data, receives the corrected first vehicle signal, and calculates from the transportation network data and corrected first and second vehicle signals the likelihood that the positions of the first and second vehicles will coincide at some time on the transportation network.

12. A system for reducing the likelihood of collision between a first vehicle and a second vehicle, 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 transportation network for generating transportation network data including at least one of:
- network capacity data, network layout data, and network traffic data, the second device further storing the transportation network data, receiving the corrected first signal, and calculating from the transportation network data and corrected first and second vehicle signals the likelihood that the positions of the first and second vehicles will coincide at some time on the transportation network.
