The Selection of Metro Freight Stations under the Mode of"Shared Lines but not Shared Trains"
The vigorous development of e-commerce has brought great pressure on urban logistics distribution and environmental protection.At present,it is a new idea to let the subway undertake part of the freight function to solve this problem.Based on the operation characteristics and future development trend of urban metro,this paper studies the metro freight transport under the mode of"shared lines but not shared trains".Combined with the operation situation and internal structure of the metro system,through the establishment of a combination model of E-TOPSIS flow screening model,set coverage model,and mixed integer programming,this paper analyzes the metro stations,and selects appropriate stations as freight stations.Finally,the freight transport scheme of urban metro under the mode of"sharing lines but not sharing trains"of metro passenger and freight trains will be realized.Finally,take Tongzhou District of Beijing as an example to carry out simulation and find out the subway stations that can carry out freight transport in Tongzhou District,so as to verify the method of selecting subway freight stations.
