Research On The Bicycle Traffic Characteristics And Bicycle Delay Model In Bus Station Area

With the development of social economy and the change of social principal contradiction,the modern urban road traffic system begins to step into the development stage of "people-oriented",and the development of slow traffic is paid great attention to.In this context,bicycle traffic has become one of the main ways for residents to travel,and the reasonable setting of bicycle lanes affects the safety and comfort of bicycle travel.However,at present,the planning and design guidelines of bicycle lanes are mostly macro regulations,and there are few detailed regulations on specific conditions.Therefore,traffic problems still exist under the participation of bicycles.Especially in the bus stop area,the interference of various traffic lines is serious,which greatly reduces the comfort and patency of bicycle running.Therefore,it is particularly important to study the running efficiency of bicycles in bus stations.This paper takes the bicycle lane in the bus station area as the research object and discusses the conflict delay problem between bicycle and other modes of transportation.Firstly,the characteristics of the mixed traffic flow of bicycle lanes are studied through the actual survey data.Secondly,the conflict mechanism and conflict delay time between different traffic modes are analyzed,and the bicycle conflict delay model is constructed.Finally,the classification of bicycle delay grade is carried out,and taken as the basis to optimize the setting of bicycle lane.Firstly,the investigation scheme was determined and investigated.Combined with mathematical statistics knowledge and SPSS,Matlab and other software,the traffic flow characteristics,trajectory characteristics,conflict interference characteristics and velocity-flow relations of each traffic mode in the bicycle lane were studied,and the isolation forms of the bicycle lane and corresponding traffic conflicts were statisticallyanalyzed.Secondly,on the basis of traffic characteristic analysis,the conflict occurrence mechanism on the road section is analyzed and the conflict types is classified,and the corresponding delay time of various conflict events is further analyzed.On this basis,the traffic conflict delay model between bicycle and bus and the traffic conflict delay model between bicycle and pedestrian are constructed,and the actual delay time is used to modify the model.Finally,the evaluation index is selected to establish the model of bicycle delay level relationship.Based on this model,the optimal setting of bicycle path is discussed.
