Video-based regional self-optimizing signal control method and apparatus

The invention provides a video-based regional self-optimizing signal control method, and mainly relates to the regional road network intersection signal optimization control field. Through comprehensive applications of a novel video vehicle detection device, dynamic detection of traffic states of multiple intersections of a regional road network as well as signal optimization can be achieved. According to the technical scheme, the method includes the steps: installing video equipment; performing data acquisition and communication; processing and calculating regional road network self-optimizing signals; and issuing and controlling signal instructions. The invention also provides a video-based regional self-optimizing signal control apparatus. Through adoption of an active video technology, the real-time traffic states of the intersections of the regional road network can be accurately detected, a regional optimized signal control scheme can be made, real-time decision and emergency handling information can be provided to traffic management and control, and the operating efficiency and the service level of regional road network traffic can be improved.
