Measurement of two-dimensional movement of traffic by image processing

A software system for measurement of two-dimensional traffic flow using moving picture processing has been developed. The proposed system is characterized by the functions classifying passing vehicles into one of three classes: motorcycle, small-and large-sized vehicles and detecting their two-dimensional trajectories on a roadway. Experiments to test the system performance have been performed and all of passing vehicles were detected by the system and were classified correctly except for only one large-sized vehicle.
