Analysis Of Urban Public Transportation Transfer System Based On Big Data

In the city’s public transportation network,the public transportation transfer is an important issue for passengers to travel.With the expansion of urban public transport,a considerable part of the travel is difficult to reach,passengers must transfer to reach their destination.In recent years,IC cards have been widely used in many cities in China.The data of urban bus IC cards is real,accurate,time-sensitive and sample-sized.It can truly reflect the urban bus operation and the characteristics of urban residents’ bus travel.Combined with the multi-source data of public transportation,we can propose new evaluation and improvement direction for the urban transportation transfer system from the perspective of big data.Based on the summary analysis of the current status of the public transfer,this paper summarizes the shortcomings of the current research status.Based on the multi-source data of the bus,the passengers get on the bus,transfer,and get off the bus,and match the passenger’s complete transfer travel chain.Establish the public transportation transfer characteristics and regular analysis framework,according to the passenger transfer travel data,Analysising of the characteristics and laws of the public transfer system from the overall and local.This paper proposes the classification and judgment method of the public transport junction,establishes the index evaluation public transport junction performance from the importance of public transport junction and transfer efficiency,and calculates the importance and transfer efficiency of 40 public transport junctions;The transfer performance of the interchange hub is evaluated and combined with the importance of the interchange hub to find the public transport junction that is most in need of optimization.The scheme for the optimization of the transfer system is proposed.Combined with the bus network and transfer system indicators,the solution to the transfer system optimization is proposed from a macro perspective,combined with the performance index of the public transport junction,and the optimization scheme for the transfer system optimization is proposed from the microscopic point of view;The paper constructs a complete system from the whole to the detail,combined with time and space to analyze,evaluate and optimize the transfer.Based on the system,the paper first analyzes the urban public transfer system and the characteristics of the urban public transport junction.The evaluation is carried out,and based on the results,an optimization scheme is proposed from the overall and partial to the urban public transfer system.
