Research On Passenger Streamline Optimization Of Integrated Passenger Hub Based On VISSIM Simulation

As a main passenger service hub,the passenger's streamline design layout is directly affected by the passenger's transfer distance,transfer time and so on,thus affecting the function of the whole integrated passenger hub.However,some of the integrated passenger hub in the planning and design stage,did not fully consider the hub of the passenger streamline design,only considered as a general function of the building,resulting in integrated passenger traffic flow within the complex cross,passenger travel distance Long,long transfer time and other issues,thus affecting the travel efficiency of passengers.At present,the optimization of passenger streamlines in China is generally completed after the completion of the integrated passenger transport hub.However,when the passenger flow line in the hub is optimized at this time,it is difficult to solve the unreasonable flow problem.Based on this,this paper chooses to study the passenger flow line optimization problem in the planning and design stage of the integrated passenger transport hub.In this paper,the basic theory of comprehensive passenger hub is taken as the starting point,and the basic theory of passenger streamline is described in detail.Secondly,the passenger streamline is analyzed and optimized,and the steps of passenger streamline analysis and optimization are put forward.Based on the streamline type,the passenger streamline is generated,and the passenger streamline bottleneck identification is carried out.According to the bottleneck identification result,the concrete optimization method is put forward from two aspects: changing the service ability and optimizing the streamline layout.The VISSIM simulation model is used to calculate the bottleneck identification,and the passenger based on VISSIM simulation is established by using the passenger flow line VISSIM simulation model to carry out the bottleneck identification and the establishment of the VISSIM simulation based on the VISSIM simulation.A Multi-level Fuzzy Comprehensive Evaluation Method for Streamline.Finally,the research results of this paper are applied to the construction of the comprehensive passenger hub.First,the passenger streamline type is determined,and then the passenger streamline is generated under the established hub layout.The VISSIM passenger streamline simulation model of the current scheme is established to identify the current scheme And then optimize the bottleneck area,and then simulate and evaluate the optimized scheme again until the evaluation result of the passenger streamline program is satisfied,and finally get the XX passenger hub Of the passenger streamline optimization program.The conclusions and methods of this paper can provide some reference for the simulation and optimization of passenger flow line of passenger hub.
