Presignal-based active public traffic signal priority control method

Abstract

The invention discloses a presignal-based active public traffic signal priority control method, which aims to ensure that the service level of public traffic vehicles which pass across crossings is improved to the greatest extent while the service level of social vehicles which pass across the crossings is not obviously reduced. The method comprises the following steps of: firstly, assembling detectors at the crossings which accord with conditions, and arranging a signal machine with computer programs and a signal lamp; secondly, setting green time differences between presignal stop lines andmain signals as well as between the presignal stop lines and presignals; thirdly, judging whether to give signal priority or not according to the operating states of crossings when the detectors detect a public traffic priority application; fourthly, judging the category of an active public traffic signal priority control strategy to be executed according to the current phase state; and finally, realizing signal priority service to the public traffic vehicles according to the control logic and the algorithm of three active public traffic signal priority control strategies of prolonging green light time, inserting public traffic phases and shortening red light time.

Description

Technical field [0001] The invention relates to a control method for public transport signal priority, in particular to an active public transport signal priority control method that combines pre-signal technology at multi-phase signal control intersections to realize public transport priority. Background technique [0002] The active bus signal priority control method is to adjust the original signal according to the bus arrival information collected by the vehicle detector set at the entrance of the intersection, and reasonably adopt the control strategies of green light extension, red light shortening, insertion phase, skip phase, phase reversal, etc. The timing parameters realize the priority of public transportation at the intersection, and maximize the capacity and service level of public transportation at the intersection. [0003] After entering the 21st century, North America, Europe and other developed countries have paid more and more attention to the research on the pri...

Problems solved by technology

However, affected by the existing research results abroad, the research direction in our country also focuses on the model algorithm and applicable conditions of the two control strategies of green light extension and red light shortening. , these two control strategies lack the priority service for the bus vehicles on the entrance road whose traffic direction is red light signal and the next execution phase is still red light signal
