The Research Of Urban Transportation Planning System Based On GIS

In the urban transportation planning, the key point of the traditional software application is to establish and solute the complex urban transportation mathematical model.The data, model and the organic relation between results expressed as well as expression and the analysis of spatial relations data with the transportation closely are not sufficient. Some spatial analyses always take more time and trouble and the datas cannot be well used, moreover the direct-viewing is not very strong, which affected the plan level. But the GIS technology has become the most useful tool of assisting the urban transportation plan because of its powerful drawing processing ability and the spatial data analytical functions. So,the paper do some application research on the application of GIS ,for example discussing integrating transportation plan model into spatial analyses,displaying various special thematic maps and attempting to develop the transportation planning system.The paper mainly concerns about:(1)Proposing the idea of completing the job using GIS software by discussing deficiency of the traditional transportation job;(2)Discussing the transportation plan algorithm and the flow, in this foundation, designing the transportation model programming realization flow chart;(3)With the comparison of the domestic and foreign GIS software platform, determining ArcGIS Desktop which has large drawing edit and spatial analyse functions as the development platform of transportation planning;(4)In the data organization and the database establishment, by using the recent object-oriented spatial data— Geodatabase and UML, completing the system database design and establishment, including spatial database, attribute database as well as transportation network database;...
