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.

Vehicle proximity detection and control systems

A system for reducing the likelihood of collision between a first vehicle and a second vehicle in an intersection. Each of the first and second vehicles 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 two signals, generating a corrected vehicle signal, and transmitting the corrected vehicle signal. A traffic flow controller controls traffic flow through the intersection. The traffic flow controller receiving the corrected vehicle signals, calculates from the corrected vehicle signals the likelihood that the positions of the first and second vehicles will coincide in the intersection, and generates a traffic flow control signal adapted to minimize the likelihood of coincidence of the first and second vehicles in the intersection.

Multiple vehicles are each equipped with a global positioning system (GPS) and a plurality of accelerometers to provide information related to vehicle's current state. A controller is provided to predict concurrent presence of at least two of the vehicles at a location at some future time. At least one of the vehicles further includes an indicator to indicate the potential for concurrent presence at the location in adequate time for the operator of the at least one of the vehicles to take appropriate evasive action to avoid concurrent presence at the location.

A first vehicle includes 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. A second vehicle includes 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, receiving the corrected first signal, and calculating from the corrected first and second vehicle signals the likelihood that the positions of the first and second vehicles will coincide at some time.
