Bus dynamic speed guidance-station control-signal priority cooperative control method

Abstract

The invention relates to a bus dynamic speed guidance-station control-signal priority cooperative control method, which comprises the following steps of S1, performing real-time bus speed guidance by adopting a bus road section speed guidance algorithm; S2, establishing a bus priority demand calculation model to calculate the priority duration, the driving speed and the parking duration of the bus priority phase demand; and S3, establishing a signal priority optimization model considering buses and other social vehicles, and optimizing an intersection signal timing scheme on the premise of meeting the bus priority phase demand. Compared with the prior art, the method has the advantages of high model robustness, real-time solution, priority effectiveness and the like, the non-stop passing rate of the bus can be effectively improved, the passing delay of the bus is reduced, the passing efficiency of the social vehicle is not reduced, and higher-quality traffic service is provided for passengers of the bus and the social vehicle.

Description

technical field [0001] The invention relates to the fields of mobile Internet bus management and intersection signal control, in particular to a bus dynamic speed guidance-stop control-signal priority collaborative control method. Background technique [0002] In recent years, transportation has gradually moved towards intelligence and mobile interconnection, and the country attaches great importance to the development of the transportation industry. However, most of the existing methods are only to adjust the signal parameters to the intersection of buses arriving at the intersection of priority traffic control, or only propose the bus speed and signal priority control, and do not simultaneously propose the optimization method of road section speed guidance, station station control, and signal priority coordination . If the coordinated control of speed guidance, station control and signal priority can be carried out on the bus priority traffic at the same time in the mobil...

Problems solved by technology

However, there is no method to simultaneously optimize the intersection signal control parameters, speed guidance, and station control. There is a lack of coordination among various control methods, and it is difficult to fully exploit the bus priority benefits brought about by the linkage of multiple control methods. Priority invalid results without coordination
