A method and system for generating a homography of a roadway traffic scene imaged by a traffic camera. Data is stored representing the global location of roadway(s) in the scene. Camera images of the scene are acquired. At least one vehicle in the scene is detected and tracked acquire its track path of the vehicle on a portion of the roadway. The track paths is matched to a corresponding globally located roadway. The result of the matching step is used to generate a candidate homography matrix. The tracking and matching of track paths is repeated for a number of vehicles, which may be traveling in a different direction on the roadway or on a different roadway in the scene, thereby obtaining a set of candidate homography matrices. The candidate matrices are evaluated and a best homography is selected.
