Operation Analysis And Optimization Research Of Urban Rail Transit In Xi'an

In recent years,with the rapid development of urbanization and mobility,the contradiction of urban internal traffic has become more and more serious,which has become the main obstacle to the rapid development of urban economy.Urban rail transit has the advantages of large passenger transport capacity,high transport speed,less environmental pollution,safety and punctuality.It can solve the contradiction between supply and demand of urban rapid growth.The number of domestic cities planning or construction of urban rail transit has reached 42.Xi'an is the only city in North West that opens and operates the urban rail transport.Xi'an urban rail transit is currently opening and having operation of two subway lines,that is Line one and Line two.During the operation,Line one and Line two of Xi'an metro,greatly changed the city development planning,rail transit network planning,rail line construction sequence and many other factors,which had a great impact on the passenger flow along the subway area.Based on the traffic data of Xi'an metro Line one and two,and the recent operation of field extraction,this thesis analyzes passenger flow growth trend of Line one and two,and sums up the spatial distribution characteristics and the matching of passenger flow and capacity.Through ability adaptability analysis on the current operation scheme of Line one and two,the thesis aims to provide foundation support for operation scheme more in line with the passenger flow characteristics,in order to facilitate the rational allocation of the line transport capacity,improve service quality,and provide better reference to the subsequent opening of Xi'an Metro lines and to the design and optimization of operation organization scheme of new built lines of other domestic cities.On the basis of the theories and practices of the railway transportation operation organizations at home and abroad,the thesis focuses on the research of Xi'an urban rail transit.Based on a large number of papers on the relevant information,the thesis has a comprehensive analysis of the present situation of Xi'an Metro Line one and two,and researches the optimization of operational problems arising in the process,which are mainly discussed as followings:(1)According to the analysis of passenger flow of the latest statistical data on station operation of Xi'an Metro Line one and two,through two aspects of daily in and out of station passenger volume and daily full station traffic,changes in the traffic and passenger flow distribution rules are analyzed and studied.(2)The current operation situation of Xi'an Metro is comprehensively analyzed through four aspects,namely operating service hours,operation cross road,daily train number,running time and stop time.(3)Compared the workday of morning peak on Monday and evening peak on Friday,non workday(Saturday and Sunday)morning and evening peak,with the existing operational capability,the thesis conducts adaptability analysis,and put forward the problems arising from the controversy whether the current Xi'an Metro transport can meet the of traffic.(4)Combined with the present operation situation and possible problems of Xi'an Metro,the thesis researches the optimization of Line one and two,including operating hour optimization,mixed routing,shorter intervals to increase the number of trains running on,and stop time optimization scheme.(5)The conclusion of the optimization of transport organization is summarized.
