Study On Waiting Regularity In Subway And Bus-to-subway Transfer Of Passengers Based On AFC Data

With the increasing demand of urban passenger flow,the backbone role of subway in urban public transport system is becoming increasingly prominent.Identifying stations with more delay,longer waiting time and poor waiting experience can provide important support for the optimization of metro train schedule and improvement of operation organization,which will help to improve the service level of metro operation.Based on this,the main contents of this paper are as follows:Firstly,a metro passenger waiting time deviation duration model is established based on train delay,passenger waiting time and passenger flow.The model includes three indexes: planned passenger waiting time,actual passenger waiting time and passenger waiting time deviation duration,which respectively represent the passenger waiting experience when the train is running in full accordance with the planned timetable,the passenger waiting experience under the actual operation of the train and the deterioration degree of the passenger waiting experience caused by the train delay.The passenger waiting time deviation duration model can be used to identify delay hot spots and stations with poor waiting experience in metro network.This paper analyzes and verifies the model with Beijing Metro data.Secondly,during the peak period of subway operation,the passenger flow at the platform of some stations is seriously congested,which leads to the delay of some passengers.It is difficult to calculate the waiting time of passengers only by the simple matching of passenger card data and train timetable.In order to solve this problem effectively,this paper proposes a calculation method of subway passenger waiting time and waiting passenger flow considering the degree of congestion.The algorithm can accurately identify the stations where passengers are delayed,and calculate the waiting passenger flow and passenger waiting time at each station platform during peak hours.Finally,an example is used to verify the analysis.Finally,the transit to subway passenger flow is also an important part of the subway passenger flow.The study of transit to subway transfer time is helpful to evaluate the efficiency of public transport convergence.Considering the uncertainty of bus passengers’ swipe time,it is difficult to determine the actual arrival time and passengers’ alighting time.In this paper,the threshold method is used to set the transfer time threshold to identify the transfer behavior of passengers;The congestion threshold at the bus door is set to estimate the actual arrival time of the bus and the time for passengers to get off the bus.Then the transfer time of passengers from the bus to the subway and the queuing time of passengers at the subway security check point are calculated.Finally,an example is analyzed with the bus data of Beijing.This paper includes 23 figures,19 tables and 56 references...
