Abstract
A vehicle traffic monitoring apparatus includes an imaging device; an image processing device; a global positioning device; and, a wireless communications system. The image processing device includes a computer program to process a data stream from the imaging device, to recognize individual vehicles substantially in view of the vehicle; and, quantify motion of the recognized individual vehicles. A second data stream is a signal output from the image processing device and includes code representing the recognized individual vehicles in view of the vehicle, quantified motion of the recognized vehicles; and vehicle position data from the global positioning system receiver. The wireless communications device receives the second data stream and communicates it a remote device. Localized traffic is monitored in metrics of traffic density, congestion, and, turbulence.
