Research On The Location Method Of Railway Passenger Station Under The Background Of Station-city Integration

The construction of China’s railways,especially the high-speed railways,is developing rapidly,and the rail travel occupy a pivotal position in the daily travel of passengers.As the demand for passenger transportation continues to increase,major cities are planning to build high-quality railway passenger stations.In recent years,concepts such as station-city integration has quietly emerged.At the same time,the railway passenger station closely cooperates with the urban planning and construction.Just as we can see that building a transportation center of the city,and using railway passenger stations to promote the further development of cities have become the goals of major cities to build new railway passenger stations.However,the development of some railway passenger stations is currently separated from urban development,and passenger stations have developed independently into isolated islands.What’s more,there is a phenomenon that the travel demand of passengers does not match the construction of the railway stations.It can be seen that the site selection and planning of the railway station is very important for the railway station to achieve the expected effect.Therefore,the research goal of this article is to propose a set of research methods on the location of railway passenger station based on the background of station-city integration.First of all,this article classifies the location types of railway passenger stations,and analyzes the typical cases and location features of each types.Next,this article summarizes the development trend and distribution characteristics of railway passenger stations,and the problems in site selection.At the same time,this paper clarifies the connotation and development model of station-city integration,and analyzes the characteristics and influencing factors of the location of railway station under the background of station-city integration.In short,these studies provide a theoretical basis for the site selection analysis of railway passenger stations.In addition,this paper divides the site selection of railway passenger station into two stages.The first stage is to generate alternative station sites,and the second stage is to optimize the site selection scheme of railway station among the alternative station sites.In the first stage,based on the consideration of the probability of passengers choosing transportation facilities,and the influence of railway stations on urban economic development,and the cost of the selection of railway station,this paper establishes an alternative station site selection model.In order to solve this model,this paper analyzes the basic ideas of approximate search algorithm and iterative algorithm,and proposes to use Visual Studio software to solve the model.In the second stage,this paper selects the evaluation indicators for the alternative site options of the railway station based on the consideration of the factors affecting the location of the railway passenger station.The author selected 17 evaluation indicators from 6 levels to construct an evaluation system,and established an evaluation model based on the BWM subjective weighting method to select the most optimal location plan.Finally,this paper designs a corresponding example to verify that the research method proposed in this paper is practical and reasonable.At the same time,in the comparative analysis of the two algorithms proposed in this paper,it can be obtained that the approximate search algorithm has higher solving accuracy,but the two algorithms have their own advantages and can be used together in research.To sum up,the hallmark feature of the development of railway station is the integration of station and city,and this article provides a new idea for the site selection of railway station,which is suitable for current practical needs.
