Title:
DYNAMIC CONTROL METHOD FOR BUS SIGNAL PRIORITY HIGH-FREQUENCY MULTI-APPLICATION
Document Type and Number:
WIPO Patent Application WO/2021/208484
Kind Code:
A1
Abstract:
A dynamic control method for bus signal priority high-frequency multi-application, having the advantages that the effect of the control method on normal social vehicles is fully considered, multi-application requirements within a single signal period are considered and the calculation efficiency is high. The method comprises the following steps: establishing a bus signal priority control model having a target of minimizing a weighted bus delay, and restricting and considering the magnitude of system disturbance (S1); performing real-time dynamic solution on the bus signal priority control model by using a receding horizon optimization method, and in the case of different bus demand levels, generating an optimized bus priority service order and a corresponding signal control solution for multi-bus priority application under various bus occupation ratios and bus station arrival deviation degrees, thereby achieving optimal ordering of bus priority services and signal control (S2).
