Logistics Distribution System Based On Urban Rail Transit And Its Application Node Research

As the widespread of e-commerce,people’s lifestyle and material needs become more and more convenient and diversified.The traditional shopping mode is gradually replaced by household shopping mode.At the same time,with the continuous acceleration of urbanization and increasing clearness of regional nature in urban land,it gradually increases the difficulty and distance of freightage in city.This makes the traditional urban logistics distribution mode,which only takes the road as the main body of transportation,can not meet the increasing pace of people’s daily life.How to use public resources reasonably,optimize the logistics distribution system,and improve the efficiency of logistics distribution has become the focus and trend of research in this field.Due to its characteristics of all-weather working hours,wide coverage,large single transportation volume,low energy consumption and high transportation efficiency,many scholars and experts believe that using urban rail transit to carry out urban logistics distribution service is one of the effective ways to solve problems of logistics distribution and transportation.On the basis of the existing research,this paper initially establishes the urban logistics distribution system based on urban rail transit,establishes the selected station where the goods need to be transferred and loaded or unloaded(referred to as the node in this paper),and designs and investigates the distribution mode,the mode of freightage and the platform area.The main research contents include:(1)From the perspective of system theory and on the basis of the traditional urban logistics distribution system,the urban logistics distribution system is initially established based on urban rail transit,the composition and function of each subsystem is specified,and the feasibility of the system is analyzed.(2)By analyzing the characteristics of time and space distribution about passenger flow of urban rail transit,this paper summarizes two urban logistics distribution modes based on Urban Rail Transit: one is to proceed logistics distribution mode of small goods in low period of passenger flow another is to proceed logistics distribution mode of large goods in the free period of rail transit,and respectively designs transportation mode of cargo in urban rail transit network under different distribution modes.(3)This paper summarizes the functions of three major logistics nodes(center central node,transit transferred node and function functional node)in the urban logistics distribution network subsystem based on urban rail transit,and respectively gives the selection methods of various logistics nodes.Among them,the enter central node selection method is based on the p-median model and the greedy extraction heuristic algorithm;the transit transferred node and the function functional node are based on their respective selection principles,relevant indicators and influencing factors,clear and definite the selection method.(4)Taking Chengdu City as an example,the data is brought in to plugging in the data and selecting each node in the rail transit network of Chengdu City,hereby so as to demonstrating the feasibility and rationality of various node selection methods for various nodes.
