Operating Efficiency Analysis And Optimization Research Of Bay Stops Based On Bus Lanes

The bay stations set along the bus lanes only occupy a small part of the whole line,but they have become the key nodes restricting the operating efficiency of the lanes.Accurate analysis of the operating efficiency of the bay station on the bus lane is of great significance to the subsequent station planning and construction,operation and management.Taking the stop site of the bus lane in Chongqing as an example,the operational characteristics,stop capacity and stop delay of the bus are analyzed through field observation and theoretical analysis.The main work and research results of this paper are summarized as follows:1.The operation process of the bus is analyzed from a micro perspective.Combining the measured data,the probability distribution function is used to calibrate the arrival distribution function and the stop time distribution function of the bus,and then the probability distribution function is fitted and verified,which lays the foundation for the later capacity analysis and delay model.2.Combined with the current situation and existing research,the impact on the capacity of harbor-type bus stations is analyzed from four aspects: personnel,bus vehicles,station design,and parking organization.3.A brief overview of the research results of the existing capacity calculation model,using the space-time analysis chart,combined with probabilistic analysis,proposed a new single-berth capacity calculation method based on the bus-only bay station.According to the parking position of the bus,the change of the berth utilization rate under different parking principles is analyzed.On this basis,the capacity of the double-berth bay station was calculated,and verified by the two methods of actual test and VISSIM simulation test,and the relative errors were 11.4%and 6%,respectively.4.The process of queuing the bus into the station-arrival service-leaving the stop is regarded as an M / M / C queuing model.This process is subdivided into different segments.The queuing theory model is combined with kinematic analysis to establish a bus.The bus station delay time model,and the simulation calculation of the model,discusses the impact of the vehicle parking position,the number of passengers,and the bus arrival rate on the station delay in different situations.5.From the aspects of planning and construction of harbor-style docking stations,optimization of bus station docking organizations,bus docking routes and bus facilities,the operational efficiency of bus stations is optimized and analyzed.
