Vehicle traffic flow data acquisition and distribution

An onboard vehicle navigation data distribution data processing system configured for vehicle traffic flow data acquisition and reporting, the system comprising:

• a plurality of cameras positioned at locations along a route of travel;
• at least one image acquisition and detection system coupled to the cameras, the image acquisition and detection system being configured to acquire imagery of vehicles passing along the roadway, to identify individual ones of the vehicles in the acquired imagery and to determine an elapsed time of travel for each of the individual ones of the vehicles between two of the cameras;
• a traffic flow data store communicatively coupled to each of the cameras and storing rates of travel for the individual ones of the vehicles for different based upon the elapsed time of travel for the individual ones of the vehicles at different ones of the locations;
• and,
• traffic flow computation logic coupled to the traffic flow data store, the logic comprising program code enabled to broadcast a rate of travel for at least one of the individually ones of the vehicles to a subscriber for a selected one of the locations.

A computer program product comprising a computer usable medium embodying computer usable program code for vehicle traffic flow data acquisition and reporting for onboard vehicle navigation, the computer program product comprising:

• computer usable program code for acquiring imagery of multiple vehicles traveling on a route of travel between two locations;
• computer usable program code for individually identifying the different vehicles in the imagery and determining an elapsed time of travel for the individually identified vehicles between the two locations;
• computer usable program code for computing a rate of travel for each of the individually identified different vehicles based upon the elapsed time of travel;
• and,
• computer usable program code for broadcasting the rate of travel for at least one of the individually identified different vehicles to a subscriber for at least one of the two locations.
