ABSTRACT:
Embodiments of the present invention provide a method, system and computer program product for vehicle traffic flow data acquisition and reporting for onboard vehicle navigation. In an embodiment of the invention, a method for vehicle traffic flow data acquisition and reporting for onboard vehicle navigation can include acquiring imagery of multiple vehicles traveling on a roadway between two locations and individually identifying the different vehicles in the imagery. An elapsed time of travel can be determined for the individually identified vehicles between the two locations and a rate of travel can be computed for each of the individually identified different vehicles based upon the elapsed time of travel. Thereafter, the rate of travel for at least one of the individually identified different vehicles can be broadcast to a subscriber for at least one of the two locations.
