Signal coordinating control method of one-road one-line straightgoing type public transport system

Abstract

The invention relates to a signal coordination control method of a one-road and one-line direct movement type public transportation system and reaches the object that public traffic vehicles fully utilize the waiting time and the transit time during the course that the public traffic vehicles pass through crossings under 'the mode of one-road and one-line direct movement' through the coordinative control of all traffic signal lamps and the corresponding regulation of transit operation to improve transit efficiency of the public traffic vehicles and reduce the delay time of the public traffic vehicles. The concrete method is that signal period lengths Ci of all the crossings are calculated; a key signal period length C0 is identified and taken as the key signal period length of all the crossings; all corresponding split/green ratio Lambadas <J>i=y<J>/ sigma y<J>i of all the crossings are calculated; a bus line equivalent distance map which takes an X-coordinate as an equivalent distance axis and takes a Y-coordinate as a time axis is established; bus line direction green light starting time differences between terminal departure stations and initial departure stations or between the signal crossings and bus line direction maximum green time length are identified through a method of 'graphical solution' is improved; therefore, a public traffic vehicle dispatching time is identified.

Description

technical field The invention relates to the implementation of the "one-way-one-line straight mode" of public transport vehicles, through the coordinated control of each traffic signal light and the corresponding adjustment of public transport dispatching, the waiting time and passing time of public transport vehicles passing through each intersection can be fully utilized, so as to improve the efficiency of public transportation. The traffic efficiency of vehicles and the reduction of delay time of public transport vehicles belong to the field of urban road traffic control. Background technique "One-way, one-way straight mode" refers to the setting of bus lines based on the road. In principle, only one bus line is laid on a road, and the bus vehicles run straight along the road. Close to the stop line at the entrance, realize the "seamless" connection of bus lines in different directions, facilitate passenger transfer, improve the operating efficiency of bus vehicles, and ...
