【摘要】 随着南昌城市建设的飞速发展,城市道路网不断扩大,道路管理部门管理的信息量与日俱增,管理工作越来越繁杂。传统的管理方法已明显不能适应城市道路建设的发展,因此非常有必要采用先进的信息技术提升城市道路交通管理的水平。而建立基于GIS技术的南昌市道路管理信息系统,将道路信息与地理信息有机结合起来,能充分发挥出地理信息系统特有的数据输入、数据输出、数据管理、空间分析以及可视化表达的功能,从而满足道路管理部门在信息检索及数据分析方面的需求,为其分析与决策提供有效的参考。本文针对南昌市道路传统管理方法的不足,提出了基于空间可视化的南昌市道路管理信息系统的结构框架,构建出支撑系统的数据库平台和地图平台。论文首先对系统研究的背景和国内外道路管理系统的发展状况进行了分析,其次对系统的基本需求和可行性进行分析,然后对地理信息系统的理论和方法进行了探讨,最后完成对系统的结构设计和数据库设计,并利用GIS组件产品MapX、SQL Server数据库和Visual Basic开发语言实现系统的主要功能。本系统是一个包括了系统管理、地图显示、图层管理、地图编辑、数据管理、数据查询、空间分析、道路信息专题图生成和测量工具等功能模块的计算机管理系统。空间数据和属性数据的管理是本文研究的基础,而道路、桥梁和人行地下通道等信息的查询显示和输出则是研究的重点。论文还针对道路网评价指标和最短路径搜索问题进行了研究。更多还原

【Abstract】 With the rapid development of Nanchang urban construction and the unceasing expansion of urban road net, the information amounts managed by road administrative department increases day by day and the management is more and more complicated. Then the traditional management methods have not been adapt to the development of the urban road construction. Therefore, it is very necessary that the advanced IT is adopted to upgrade the city’s road traffic control. But the road management information systems of Nanchang based on GIS technology was built, which is organically combined with the road information and the geographical feature information. The model fully displays the geographic information system’s unique data input, the data output, the data management, the spatial analysis as well as the visualization expression function fully, so it can satisfy the need of the road administrative department in the field of the information retrieval and data analysis and provide effective reference for its analysis and decision.Aimed at the deficiencies of traditional management of Nanchang urban road, the framework of urban road management information system based on spatial visualization was brought forward and the database and map platform were constructed. First of all, the paper analyzed the background of the system and the development status of the road management systems at home and abroad. Followed by the analysis on the basic needs and feasibility of the system, the theory and methods of the geographic information systems were discussed. Finally, the design of the structure and Database were completed and the core functions of the system were realized, which made use of the components of GIS products MapX, SQL Server database and VB language.The system is a computer management system and it includes functional modules such as system management, map display, management of the map layer, the map edition, the data management, the data query, the spatial analysis, the generation of thematic map for the road information and measurement tools. The management of spatial and attribution data is the basis of this paper. And the focus of this paper is the query, display and output of information for roads, bridges and pedestrian underpass. In addition, the problems of the road network evaluation and the shortest path search are also studied in this paper.更多还原
