Research And Application Of Bus Operation Index Based On Big Data

With the rapid development of social economy,urban rail and road traffic congestion has become more and more serious.In order to alleviate this problem,traffic management departments and research institutions at home and abroad have developed a variety of traffic operation index models suitable for each city from different perspectives.These existing traffic operation index models can accurately reflect the real-time operation of urban road traffic,but they can hardly reflect the operation of urban public transport.However,the bus is the most important vehicle for passenger transportation in the city.The advantages and disadvantages of its operation status and improvement play an important role in solving the problem of urban rail and road traffic congestion.Therefore,based on the existing bus operation data,this paper analyzes and constructs the bus operation index system,and studies the operation index which can accurately reflect the urban bus operation status.Firstly,this paper analyzes the data required for the research of bus operation index.The required data include static data of the bus line,GPS data of the bus,GPS data of the floating vehicle,and data of the passenger transport turnover.The required data are processed and screened accordingly to obtain the data specifically required.Secondly,this paper put forward the index system of the basic principles,based on the principles of the construction of index system,and from the four important factors influencing the bus running status(open degree,bus running status of the bus to run their own differences,bus operation stability and compared with the difference between other modes of transport)to build an index system of bus running,and the index system of the four core index were determined,respectively,both index,travel time ratio,stability and service with floating car travel time ratio,and gives the corresponding calculation method;Based on the four key indicators to determine the bus running comprehensive index,and from both index,the travel time ratio,stability and service with floating car travel time than the four core index to analyze the influence degree of the bus operation index,considering the four core index of bus operation should have the same importance,the impact of proposed reasonable bus run comprehensive index method and bus operation index calculation method and corresponding bus running status hierarchy.Finally,taking Guangzhou city as an application case,the accuracy of the bus operation index is verified.By selecting the appropriate case line,the core index,comprehensive index and bus operation index of the selected bus line and line network are calculated from different time and space dimensions.According to the calculation results,the operation status of the selected line and line network is analyzed,and the analysis results show that the bus operation time characteristics,road grade and other line attributes are the main factors affecting the bus operation status,and according to the corresponding analysis results,some relevant effective Suggestions are proposed.
