【摘要】：道路交通信息管理平台是地理信息系统在交通管理方面的一个应用，是智能交通系统的一个重要组成部分。随着道路的发展，如何将海量道路数据空间信息和属性信息统一管理，数据实现动态更新，路径实现动态规划及显示，是设计开发交通地理信息管理平台需要考虑的问题。ArcGIS作为主流的地理信息系统软件，它在数据模型建立、数据更新管理及数据处理框架上都有完整的解决方案，且对数据的管理具有精确、快速、广泛以及综合性强等优点，因此以ArcGIS为软件开发平台，设计开发道路交通信息管理平台具有一定的实际意义。论文主要围绕道路交通信息管理平台的数据动态更新，路径动态规划和显示问题展开工作，主要工作内容如下： 1、研究了ArcGIS空间数据组织与管理技术，介绍了Geodatabase的功能及特点，重点对Geodatabase的存储及访问方式进行了分析比较，同时对空间数据库引擎ArcSDE的功能和作用进行了阐述，在此基础上，使用城市道路交通基础数据建立了道路空间数据库，并依据平台需求对数据进行相关的改造，同时构建了道路几何网络、属性域，实现了对数据库的动态更新设计。 2、研究并实现了常用的三种路径规划算法，通过对三种算法效率的比较分析，采用Dijkstra算法来解决所设计平台的路径规划问题。使用道路交通的基础数据创建了网络分析数据，，生成了网络图层，并在网络分析中添加了道路的阻力值信息，同时通过arcEngine提供的相关类库接口及路径分析图层，在系统中实现了路径的动态规划与显示。 3、根据需求，对道路交通管理平台进行了总体设计，给出了数据库详细结构，对模块进行了划分，并采用ArcEngine的组件开发技术，以Microsoft visual studio为开发平台，使用C#语言，实现了模块的功能，实现了道路交通地理信息管理平台的设计。 4、对论文工作进行了总结，同时还指出了系统实现过程中存在的问题和目前功能方面的不足，明确了下一步研究工作的目标。
[Abstract]:Road traffic information management platform is an application of GIS in traffic management and an important part of intelligent transportation system. With the development of the road, how to manage the massive road data spatial information and attribute information, how to dynamically update the data, how to realize the dynamic planning and display of the path, ArcGIS, as the mainstream GIS software, has a complete solution in the framework of data model building, data updating management and data processing. And the data management has the advantages of accurate, fast, wide and comprehensive, so it is of practical significance to design and develop the road traffic information management platform with ArcGIS as the software development platform. This paper mainly focuses on the dynamic updating of the data of the road traffic information management platform, the dynamic path planning and display problems. The main work is as follows: 1. Research the ArcGIS spatial data organization and management technology. This paper introduces the functions and characteristics of Geodatabase, analyzes and compares the storage and access methods of Geodatabase, and expounds the functions and functions of spatial database engine ArcSDE. Using the basic data of urban road traffic, the road spatial database is established, and the relevant data are transformed according to the platform requirements. At the same time, the road geometric network and attribute domain are constructed. Secondly, three common path planning algorithms are studied and implemented. By comparing and analyzing the efficiency of the three algorithms, Dijkstra algorithm is adopted to solve the path planning problem of the designed platform. Using the basic data of road traffic, the network analysis data is created, the network layer is generated, and the road resistance value information is added to the network analysis. At the same time, the interface of the relevant class library and the path analysis layer are provided by arcEngine. The dynamic path planning and displaying are realized in the system. According to the demand, the overall design of the road traffic management platform is carried out, the detailed structure of the database is given, the modules are divided, and the component development technology of ArcEngine is adopted. Taking visual studio as the development platform and using C # language, the function of the module is realized, and the design of the road traffic geographic information management platform is realized. 4. The work of this paper is summarized. At the same time, it points out the problems existing in the realization of the system and the deficiency of the function at present, and clarifies the goal of the next research work.
