Embodiment
[0055] The method of the present invention based on the traffic signal control machine dynamically matching the optimal signal timing scheme, the method is to formulate the signal light timing scheme through the traffic signal scheme experts, and set the corresponding rule judgment value in each signal light timing scheme, and the formulated The signal light timing scheme is stored in the traffic flow-signal scheme database; the real-time traffic flow of each lane is collected through road cameras or vehicle-mounted GPS, the traffic flow data is analyzed and judged by rules, and the dynamic programming algorithm is used to match in the traffic flow-signal scheme database To the optimal signal light timing scheme; the specific steps are as follows:
[0056] S1. Planning and construction of the vehicle flow-signal scheme database; wherein, the vehicle flow-signal scheme database includes a flow table (car_flow), a timing scheme table (signal_list), and a signal scheme issuing rec...
