Study On Optimization Of External Traffic Connection Of Tianjin Metro Line 3

With the development of public transportation in recent years,urban rail transit has become the main mode of transportation used by urban residents when they travel.Because of its advantages of fast speed and large passenger carrying capacity,now it is the transportation network skeleton of every city with subway.However,the travel of rail transit needs to be combined with other modes of transportation to complete the transportation of pedestrians.Therefore,it has great significance to study the connection planning between rail stations and other types of transportation modes,so as to better improve the integration level of connection between stations and other urban transportation modes,as well as the travel efficiency of travelers,and make the whole transportation network more efficient and fast.On the basis of studying the optimization of different connection modes,this paper focuses on the analysis of green connection modes,and aiming at achieving seamless transfer of stations.The main contents of this paper are as follows:1.Analyze the classification methods of urban rail transit stations at home and abroad,and select the cluster analysis method to classify the stations of Tianjin Metro Line 3.2.This paper analyzes the model of passenger flow forecast,the characteristics of different connection modes of rail stations,the calculation method of Facility Scale and the principles and requirements of layout.By studying the layout form of actual stations and the requirements of the guidelines for the configuration of connection facilities,this paper puts forward suggestions on the configuration and layout of connection facilities for different types of stations of Tianjin Metro Line 3.3.Finally,the mixed logit model and nested logit model in the discrete choice model are selected to predict the pick-up passenger flow of the selected stations,and the characteristics of the passenger pick-up mode are analyzed according to the estimation results of the model,so as to provide a certain basis for the final optimization suggestions.4.Through the comparison with the current situation of the stations,the scale calculation and layout analysis of the connection facilities of the selected types of stations are carried out,and the corresponding optimization suggestions are put forward.
