The Research On Control System For Bus Priority Signal

With the rapid development of social economy and urbanization, the urbantraffic congestion is becoming more and more serious. By developing publictransport to solve urban traffic congestion problem has become a focus for thetransport workers at home and abroad. In the urban traffic, arterial signalcoordination control is a kind of common control mode. If the bus priority controlstrategies implemented in arterial coordination control may affect the effect ofarterial coordination control. Therefore, Study how to achieve coordinated controlwithout affecting the trunk on the basis of the effect of bus priority control hasimportant practical significance.In order to solve bus priority in arterial coordination control system，Thispaper puts forward the Judge conditions for Bus priority principle base on Buspriority principle in Transmodeler. According to the judgment conditions establisharterial signal coordination control framework for bus priority,The control systemcontains two layers, Upper for common arterial signal coordination control, Lowerfor coordinated control of bus priority signal timing optimization,According topublic transport vehicles phase，set up the coordination phase bus priority controlalgorithm and the un-coordination phase bus priority control algorithm, anddetermines the priority control strategy of each phase after timing parameters. Toverify the proposed for bus priority of efficiency and the feasibility of arterialsignal coordination control, Willow Road in Zibo District as the Case, Select LiuQuan road-in embellish avenue, Liu Quan road-Lian tong road, Liu Quan road-hua guang road, Liu Quan road-ren min road, Liu Quan road as the Arterialcoordination system. The simulation system is established in Transmodelersoftware and add transit signal priority, simulation the presence of bus signalpriority under arterial coordination control, With reference to the simulationresults of roads and intersections output data contrast analysis, the simulationresults show that the control algorithm can effectively reduce the car averagedelay and to improve service levels...
