Optimization Study On Passenger Flow Organization Of Comprehensive Integrated Transportation Hub

Transfer function is one of the core functions of the integrated passenger transport hub,and it is also a concentrated reflection of the operational efficiency and service level of the integrated passenger transport hub.At present,the research on the optimization of passenger flow organization is mainly promoted by scholars in the field of "transportation",focusing on the relationship between passenger flow and facilities size and number of equipment,as well as the optimization simulation of passenger flow organization,ignoring the impact of building functions on passenger flow activities,and easily falling into the predicament of "passive coping,the problem can not be thoroughly solved".On the basis of summarizing the design methods and principles of passenger hub streamline,and combining with the theory and methods of passenger flow organization optimization,this paper studies the optimization of passenger flow organization for passenger exchange in integrated passenger hub.Firstly,the functional composition and transfer function of the integrated passenger transport hub are analyzed to understand the main functions and functions of the transfer space under different layout modes;the transfer space is divided into different research areas and spatial units to find out the impact of transfer space on passenger transport hub,and the effect of transfer space size on service level of passenger transport hubs from the perspective of passenger behavior and facility layout.Then,using the description of “streamline” to express the activity of passenger flow in the passenger transportation hub,and analyze the four types of streamline conflicts such as confluence,diversion,crossover and inversion of the transfer streamline,it is found that in the same space,the greater the conflict caused by the change of passenger flow,the more serious the impact of the conflict is;in the same degree of flow,the conflict degree of the streamline is from large to small: crossover,confluence,diversion and inversion.On the basis of analyzing the influencing factors of passenger flow organization,the target level classification expansion method is used to analyze the passenger transportation hub from the overall perspective to the research area step by step,and build the evaluation system of passenger flow organization for comprehensive passenger transport hub.It also analyzes the passenger flow organization optimization process of the integrated passenger transport hub,explores the passenger flow organization optimization method and the specific implementation path of the passenger transport hub.Finally,an example is given to illustrate the application of the theory and method in the optimization of passenger flow organization in Chengdu East Integrated Passenger Hub.Based on the analysis of the current situation of passenger flow organization in Chengdu East Passenger Hub,it is found that the disorder of passenger flow organization in the transfer hall and the unreasonable layout of some functional facilities are the main factors causing the "chaos" of passenger flow organization in the passenger hub.Then,taking the transfer hall as an example,the minimum disorder degree of transfer passenger flow organization is set as the objective function,based on the consideration of bypass coefficient,comfort and space utilization,the optimization scheme of transfer hall facilities layout and transfer passenger flow organization is designed,and the optimization scheme is evaluated.
