The invention relates to a regional traffic coordinating and optimizing
control system and method based on vehicle average
delay. The regional traffic coordinating and optimizing
control system comprises intersection nodes and a regional coordinating control node. The intersection nodes are used for collecting local
traffic flow status information and outputting a timing plan of an intersection; and the regional coordinating control node is used for collecting regional road network
traffic flow statuses, coordinating control over all intersections and outputting timing plans of all the intersections. The regional coordinating control node comprises a traffic information collecting module, a coordinating and optimizing module and a timing plan outputting module. The traffic information collecting module is used for collecting the
traffic flow statuses of
road networks; the coordinating and optimizing module is used for coordinating and optimizing the
signal timing plans of all the intersections through a multi-intersection coordinating control device; and the timing plan outputting module is used for outputting the timing plans coordinated by the coordinating and optimizing module to all intersection nodes to be carried out. According to the regional traffic coordinating and optimizing
control system and method based on vehicle average
delay, dynamic characteristics of the regional road network traffic flow are analyzed, with the purpose of minimum vehicle
delay, a regional vehicle delay model and the coordinating control method are established, according to the high-dimensional feature of the delay model and the
system real-time requirements, a chaos
genetic algorithm is adopted to coordinate, optimize and control the regional traffic signals, and the traffic efficiencyof the regional
road networks can be effectively improved.
