A signal priority control method for rapid transit during peak hours

Abstract

The invention discloses a prior control method for a bus rapid transit signal during traffic peak duration. By comprehensively considering prior traffic requirements of bus rapid transit vehicles and basic traffic constraints of non-prior motor vehicles, non-automatic vehicles and pedestrians, the prior traffic of the bus rapid transit vehicles is realized on the basis of guaranteeing normal operation of intersections. The specific method comprises the steps of firstly, collecting basic data including rapid bus route information, intersection traffic flow and flow direction information, intersection canal design and signal timing plans and the like; secondly, constructing a non-prior phase minimum green light requirement time and signal prior control model; and finally, according to the time of reaching the intersections of a bus rapid transit, calculating real-time green light time of each phase and generating a bus rapid transit signal prior control scheme. The method is simple and practical, great in stability and wide in application range and can be widely applied to engineering practice.

Description

technical field [0001] The invention relates to a priority control method for express bus signals during traffic rush hours without causing operation disturbance of non-priority phases. Background technique [0002] China is in the rapid development period of urbanization, the number of urban motor vehicles is increasing day by day, and the road traffic load is increasing. Especially during morning and evening traffic rush hours, a large number of motor vehicles flood into urban roads, and intersections are often in a highly saturated state. Priority control of BRT signals is implemented at intersections in high saturation state, and motor vehicles controlled by non-priority phases are deprived of the right of way for part of the time, and their intersection passing capacity is reduced. Therefore, the queuing of vehicles at intersections is too long, vehicles overflow to upstream intersections, and traffic disorder at intersections and road sections occurs from time to time...
