Research On Optimization Of Rural Public Transport Network Based On Mobile Signaling Data

In recent years,the traffic situation in rural areas has changed dramatically and the accessibility rate of rural public transportation is getting higher and higher.With the gradual development of rural public transport,how to optimize the bus network to lay the foundation for the sustainable development of public transport has become a new problem for managers to face.With the help of the comprehensive and accurate characteristics of mobile phone signaling data,the optimization method of bus network in rural areas is proposed to provide help for the improvement and development of public transport in rural areas.Firstly,analyze the spatial distribution and time distribution of passenger flow in rural areas,and summarize the characteristics of passenger flow distribution.Find out the existing problems of public transportation in rural areas,and analyze the reasons for the problems in combination with the characteristics of passenger flow distribution.Give the classification of demand-response public transport,and list demand-response The application advantages of public transport,and the development of demand-response public transport in rural areas of my country.Secondly,delete the error data,correct the moving distance error and correct the influence of factors such as operator occupancy rate and the number of mobile phones per capita.Identify the parking position based on time,space and speed thresholds,and describe the user’s activity process.Calculate the user’s travel time Feature data,and perform cluster analysis based on Gaussian mixture model to identify the main transportation modes during travel.Use car travel data to count the heat value of road nodes.Use bus travel data to obtain the distribution and the OD data of bus demand.Thirdly,according to the compositional relationship between the bus line network and the lines,an evaluation index system of the bus line network in rural areas with the line layout,bus coverage and passenger travel as the main content is constructed,and the quantitative standard of the evaluation index is determined.Calculate the weight of bus line indicators by using objective weighting method and Calculate the weight of the overall line network index through expert scoring and subjective evaluation method.Finally,the main flow and distribution of public transport demand are analyzed,and the method for determining the passenger flow of public transport corridors and stations is given.According to the current situation of public transport demand,demand-response public transport is introduced and the composition structure of public transport supply is proposed.The idea is to propose the layout optimization process of the bus trunk line,and build a model to determine the direction of the new line and the location of the stations along the line.With the goal of maximizing the passenger flow,establish the layout model of the demand-response bus,and use the simulated annealing algorithm to solve it to form the branch bus line.Layout plan.Take Pingdu as an example to demonstrate the research process and verify the effectiveness of the method.
