Distinguishing Method Of Arterial Fleet Considering Minor Traffic Flow

Because the platoon dispersion characteristics must be considered in the process of traffic control system research,it is necessary to study the influence of Platoon dispersion on traffic control system.At present,China's economic and urban construction are still developing rapidly,China's traffic is still not in the stage of improvement,due to the large distance between urban road network spacing,road structure and vehicle composition are more complex and poor traffic awareness and other factors.The urban road platoon dispersion caused a great impact.On the basis of elaborating the research results of traffic flow characteristics at home and abroad,this paper studies the influence of branch traffic flow on the dispersion characteristics of main road traffic flow and the fleet identification method in the case of branch traffic flow.The paper is divided into six chapters,the main research is as follows:The first chapter introduces the research background,research purpose and significance,research status and research content and research framework.The second chapter builds the vissim simulation platform,the influence of the branch flow on the platoon dispersion characteristics is studied emphatically,and the influence of the traffic flow on the reorganization of the trunk road is analyzed;At the same time,the influence of road structure and traffic flow on the dispersion characteristics of main road traffic is summarized and analyzed.In the third chapter,on the basis of the previous chapter,we find the method to determine the index of the fleet.Based on the traffic volume,the branch flow,the downstream section(road length)and the branch import position as the variable,The influence of the four variables on the discriminant index of the trunk fleet is analyzed.The fitting function is found by fitting the method.In the fourth chapter,through the analysis and research of the third chapter,the paper puts forward the fleet judgment model considering the import flow of the branch traffic road.Then,based on the actual survey data of Changchun City,the model parameters are calibrated.Finally,The validity of the model is verified by the actual survey data.The fifth chapter puts forward the case analysis and application of the fleet judgment model,and carries on the intersection induction signal control.These include:(1)single point intersection sensor signal control,put forward the induction signal control strategy,and based on the actual survey data,with vissim software for simulation;(2)Considering the influence of the upstream intersection on the downstream intersection,the coordinated control strategy of the trunk coordination is proposed.The sixth chapter summarizes the contents of the paper,and then puts forward the prospect of the next research work.
