Research On Decision Technic For GIS-Aided Station Locating In High-Speed Maglev Railway

As the new passenger transportation facility during medium and long distance of 21st Century, high-speed maglev railway's advanced technique is the focus of us all. The problem of station distributing is the main thesis during the programming and designing stage of the line. Stations are windows to provide service to guests and base of itself to operate for the high-speed maglev system. Locating of stations as an important part of station distributing, can ensure the technical and economical rationality and nice social benefit to realization.Started from the supporting tools for cartography at the beginning, now Geographic Information System (GIS) has developed to be a method applied in almost all engineering, research and management, where spatial information is available. To solve the problem of stations locating, many aspects must to be considered, such as the politics, economy, natural conditions and civilization atmosphere. The information to be used include graph and image, statistic data, character recodes, programming request etc. How to organize, manage and use them effectually is the strongpoint of GIS. The research and study of the way to realize GIS-aided station location choice for high-speed maglev railway has theory and practice signification, which can improve the development of the GIS-based research on transportation and programming and designing technique of high-speed maglev railway. Using the experience of station locating on conventional railway for reference, in this paper, the method to choose the stations' location that can bring its advantage on technical-economical into play is put forward, considering the particularity of high-speed maglev railway. More over, the method is put in practice by reprogramming on the GIS environment.The following research work has been carried out in this paper:1. The commonness between high-speed maglev railway and the conventional railway on station locating and the particularity of the later is studied. The main factors influencing the decision of station point of high-speed maglev railway are analyzed deeply.2. Take the experience of conventional railway in solving this problem forreference, considering the function of spatial analyze and advantage in solving problems of GIS, the idea and method of GIS-aided station locating on high-speed maglev system is brought forwards.3. With the direction of the idea above, Maplnfo Professional 7.02 is chosen as the GIS work condition to obtain and organize information, Mapbasic language is used to reprogram to add new function module to the GIS system.4. An example case is given to show the feasibility of the idea put forward.
