Abstract: The GIS?based highway monitoring and commanding traffic scheduling system has poor intelligent visual acquisition and processing effect of road traffic information, resulting in poor traffic scheduling effect. Therefore, a traffic scheduling system based on intelligent vision is designed. The system is mainly composed of the ZigBee coordinator module, intelligent vision module, and traffic control base station. The ZigBee coordinator module is adopted to process vehicle information and coordinate the scheduling performance of the system. In the intelligent vision module, the vehicle?mounted sensor node module is used to collect road information during traffic congestion, and control the volume of vehicle?mounted sensor nodes, and the overall energy and capital consumption of the system. The road image information acquisition and processing module is used to realize real?time feedback of congested vehicle image information. An optimization disposal algorithm based on hybrid fish swarm algorithm is designed to resolve the vehicle scheduling problem during traffic congestion. The experimental results show that the designed system has good traffic scheduling effect and strong applicability.
