The Study On Passenger Flow Organization Of A T-type Transfer Station Based On Anylogic

Urban rail transit is an effective way to alleviate the problem of traffic congestion in cities as the advantage of large transport capacity,punctuality,fast,light pollution,safety,comfort and of occupy less urban roads.In the urban rail transit system,the interchange station serves as a key node for passenger flow exchange between the various lines within the system,under peak passenger flow conditions,it is necessary to study how to rationally optimize its passenger flow organization through various measures to improve the efficiency of the passenger flow organization to the entire system plays a decisive role.In addition,Conduct systematic research and efficiency evaluation on the passenger flow organization of rail transit transfer stations are have a great significance to improve the efficiency of passenger flow organization at the transfer station,the satisfaction rate of passengers with rail transit services,and optimize the design and planning of the transfer station.In this paper,taking Xiaozhai transfer station of Xi’an Metro as an example,taking passenger flow organization of “T”-type transfer station as the research object,and specifically completes the following work:This paper first expounds the theory of “T”-type transfer station in China urban rail transit transfer station,and analyzes the basic transfer mode of “T”-type transfer station,the characteristics of passenger flow during the rush hour,and the principles of passenger flow organization in detail.Then,the reasons of the bottleneck in stations are analyzed in detail from three aspects as passenger flow,facility and operation organization.Taking equipment and facility,passenger flow line and train operation Organization as breakthrough points,then the optimization method of passenger flow organization is put forward.And the classification standards of the service level of various scholars for urban subway transfer facilities are summarized according to the relevant specifications.In the end,the service level classification standard which is fit for Xiaozhai Station is given based on different point of view of scholars.The service level index is used to evaluate the passenger flow organization plan and determine the effectiveness of the passenger flow organization optimization.Next,taking Xiaozhai Station of Xi’an Metro as an example,conducted field investigation and pedestrian observation,obtained the passenger flow data during peak hours,and analyzed the passenger volume,passenger flow characteristics and passenger flow lines about Xiaozhai Station.Through the analysis of passenger flow organization during the morning and evening peak hours of Xiaozhai Station,the problems in this mode are obtained.Therefore,it is necessary to reasonably optimize the current passenger flow organization to ensure that the pressure of passenger flow during the rush hour at Xiaozhai Station can be alleviated.Finally,we use Anylogic Simulation Software to simulate Xiaozhai Station through environmental modeling and process modeling.The density heat map and density curve of the station hall,the platform of Line 2 and the platform of Line 3 are obtained.At the same time,the service level of each facility during peak hours is also calculated.By analyzing the simulation results,specific optimization measures are put forward in terms of improving passenger flow lines and the application of diversion railings.The improved scheme is simulated and analyzed to verify its effect and whether the service level has been improved.In the end,it is concluded that the service level of the station hall and the platform of Line 2have no change,the passenger flow density all decreased,the service level of the platform of Line 3 changed from C to A,and the highest value of passenger density changed from 0.57 to0.25.It is hoped that a theoretical reference for the optimization of passenger flow organization method of “T”-type transfer station can be provided through the study of the passenger flow organization of Xiaozhai Station,and it is hoped that it can be used as a reference for the planning and design of new subway transfer stations at the same time.
