Study On The Configuration Of Transport Connection System For Large-scale Integrated Passenger Terminal

The large-scale integrated passenger transportation terminal is the distribution center of the external transportation and the internal transportation of the city.The rationality of the configuration of the traffic connection system is directly related to the efficiency of passenger flow distribution in hub.At present,large-scale integrated passenger transportation hubs are planned and built in many large cities in China.However,due to the constraints of our country's advanced management system,the allocation of transportation modes in the hub is often configured separately.There is a lack of systematic and overall planning in the transfer connection,which makes the problems such as the connection between the external and internal transportation modes of the hub not smooth,disorderly layout of traffic connection facilities in hub,more the crossing point of the transfer streamline,the long walking distance of passenger transfer and mismatched transport capabilities became more prominent.Based on this,this paper studied the configuration of a large integrated passenger transportation hub.At first,the paper introduces the concept and functions of the large-scale integrated passenger transport hub,the concept and connotation of traffic connection,and expounds the relevant theories,which provide strong support for the study of the traffic connection system configuration of the large-scale integrated passenger transport hub.Secondly,the transfer passenger flow prediction of the hub is completed in three steps.The first step is to predict the quantity of urban railway passenger transport by using the grey markov model.The second step is to predict the traffic flow of the hub by using the proportional method through the analysis of the hub location,the position of the hub in the urban external transportation system and the urban development policy and other factors.In the third step,based on the analysis of the influencing factors of passenger flow,the correlation analysis method is used to determine the main influencing factors for passengers to choose transit modes,namely connection costs,transfer time costs,comfort,and the model of passenger flow prediction is established by using the non-set logit model.Then,from the microscopic point of view,the multi-objective spatial layout optimization model is established by selecting the shortest walking time and the minimum average cross-collision delay of passengers on the basis of the flow of passengers.Genetic algorithm is used to solve the layout optimization model.Again,from a macro perspective,based on the distribution of passenger flow in different directions of the hub,with the operation or maintenance cost minimum of the traffic linkage system as objective function,a macro configuration model of the traffic convergence facilities is established to configure transportation capacity and lines in all directions of traffic linkage facilities synthetically.After that,according to the characteristics and principles of traffic connection system evaluation,the evaluation index system of traffic connection system is established from three aspects: facility capability matching,facility layout rationality and connection organization validity,and a comprehensive evaluation model of traffic connection system is constructed with the matter element theory.Finally,taking Chongqing East Railway Station as an example,the application method of the traffic connection system proposed by the dissertation is applied to the example.The result proves that the configuration method of the large-scale integrated passenger transport hub connection system proposed in this paper has a certain degree of scientificity and implementability.
