Study On The Bus Priority Control Technology Of Urban Road Network

Paper studied bus priority strategies based on city bus priority concept, detector emplacedoptimization method, the technology of information acquisition and processing and predictedpublic transport vehicles operating parameters, which provide the basic data single bus priorityand the network bus priority. On this basis, considering with the constraints of bus Weightcoefficient, optimization parameters and other factors, establish bus priority to optimize targetmodel. Then, under the objectives, paper studied the single and network bus priority.On the basis of the above objectives, the paper start from the bus priority signal controlstrategy, based on different concept of bus priority, proposed bus priority control methodaccording to the structure of the urban road network, traffic composition, road conditions and soon. Subsequently paper studied the demotion strategy and different bus lines priority levelpartitioning technique, constructed bus priority control constraints considering with the roadnetwork, road and traffic conditions and control strategies. According to the above research, weproposed bus priority re-calculation method, establish per capita delays and overall delay underdifferent control strategies optimization of parameters in order to optimize target model. Finally,we studied the single intersection bus priority and regional road network bus priority, Whensingle-phase bus traffic intersection exists, analysis of the single intersection bus priority controlstrategy, control processes as well as the single intersection bus priority control optimization goals,determine single intersections bus priority optimizing the control parameters. Finally, an exampleto test the bus priority, and laid the technical foundation for the follow-up chapters. Throughoutthe whole paper，we proposed public transport priority coordination control technology based onthe bus weight coefficient calculate method, and on this basis, we evaluate the network buspriority system, and ultimately optimize goal of bus priority coordinated control in road network.It is an explore to road network bus priority coordinated control of relevant research methods,research contents and research findings in this paper, Which can provide the theoretical basis forthe construction and management of the urban intersection.
