Triggering type bus priority control method based on real-time position matching

Abstract

The invention discloses a trigger type bus priority control method based on real-time position matching. The method comprises the following steps: S1, obtaining bus real-time data; s2, matching a trigger area, acquiring an intersection corresponding to the matched trigger area, judging a locking state flag executed preferentially by a bus at the current intersection, if the locking state flag is the locking state, returning to S1, and if not, monitoring real-time phase information, acquiring a current execution stage S and acquiring a signal to control a bus stage P; and S3, obtaining a bus priority scheme according to the current execution stage S and the signal control bus stage P.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, and more particularly to a method for triggering bus priority control based on real-time position matching. Background technique [0002] The so-called "bus signal priority" is an implementation method of "bus priority" in urban traffic. It optimizes the design of the signal control scheme for urban road intersections to achieve the goal that public transport vehicles pass through intersections prior to social vehicles. The priority control of bus signals can greatly improve the traffic capacity of urban road public transport vehicles, indirectly encourage residents to choose bus travel modes, and help promote the development of public transport. In today's increasingly steep urban traffic pressure, this control method is of great significance for quickly evacuating traffic pressure and alleviating traffic congestion. [0003] At present, the existing bus priority algo...

Problems solved by technology

[0003] At present, the existing bus priority algorithm is to directly lock the corresponding bus phase after judging that the bus is at a certain intersection, and there will be events such as phase jumps and instantaneous disappearance of the current phase that create traffic flow chaos. In addition, the existing scheme Among them, in addition to installing GPS positioning equipment, buses also need to install induction equipment. At the same time, at the intersection, it is also necessary to use the induction receiving equipment to judge whether the bus appears at the intersection. The problem of triggering the signal machine will greatly interfere with the traffic flow of the road network. With the continuous development and expansion of the city, the travel demand of residents has increased sharply, and the coverage of bus lines at each intersection in the urban area is relatively high. The traditional bus signal priority method can no longer meet the actual situation. need
