More Information
Summary:The invention relates to an adaptive traffic signal timing method, relates to the field of traffic signal control, and solves the problem that a traffic timing scheme method, which is guided by an artificial method and fits in different time periods in the prior art, cannot perform multi-node coordinated control on an area according to real-time traffic information. The adaptive traffic signal timing method in the invention comprises the steps of: (1), obtaining video image information of an intersection; (2), performing gray-scale processing on the video image information; (3), processing a video image by utilizing mean filtering and median filtering; (4), processing a video image sequence frame by frame by adopting opening operation in morphology; (5), establishing a background model, and updating the background model in real time; (6), in combination with a frame difference method and a background difference method, detecting a moving object, and counting the target number; and (7),obtaining an area timing
