【摘要】：道路交通信息管理平臺是地理信息系統(tǒng)在交通管理方面的一個應(yīng)用，是智能交通系統(tǒng)的一個重要組成部分。隨著道路的發(fā)展，如何將海量道路數(shù)據(jù)空間信息和屬性信息統(tǒng)一管理，數(shù)據(jù)實現(xiàn)動態(tài)更新，路徑實現(xiàn)動態(tài)規(guī)劃及顯示，是設(shè)計開發(fā)交通地理信息管理平臺需要考慮的問題。ArcGIS作為主流的地理信息系統(tǒng)軟件，它在數(shù)據(jù)模型建立、數(shù)據(jù)更新管理及數(shù)據(jù)處理框架上都有完整的解決方案，且對數(shù)據(jù)的管理具有精確、快速、廣泛以及綜合性強(qiáng)等優(yōu)點，因此以ArcGIS為軟件開發(fā)平臺，設(shè)計開發(fā)道路交通信息管理平臺具有一定的實際意義。 論文主要圍繞道路交通信息管理平臺的數(shù)據(jù)動態(tài)更新，路徑動態(tài)規(guī)劃和顯示問題展開工作，主要工作內(nèi)容如下： 1、研究了ArcGIS空間數(shù)據(jù)組織與管理技術(shù)，介紹了Geodatabase的功能及特點，重點對Geodatabase的存儲及訪問方式進(jìn)行了分析比較，同時對空間數(shù)據(jù)庫引擎ArcSDE的功能和作用進(jìn)行了闡述，在此基礎(chǔ)上，使用城市道路交通基礎(chǔ)數(shù)據(jù)建立了道路空間數(shù)據(jù)庫，并依據(jù)平臺需求對數(shù)據(jù)進(jìn)行相關(guān)的改造，同時構(gòu)建了道路幾何網(wǎng)絡(luò)、屬性域，實現(xiàn)了對數(shù)據(jù)庫的動態(tài)更新設(shè)計。 2、研究并實現(xiàn)了常用的三種路徑規(guī)劃算法，通過對三種算法效率的比較分析，采用Dijkstra算法來解決所設(shè)計平臺的路徑規(guī)劃問題。使用道路交通的基礎(chǔ)數(shù)據(jù)創(chuàng)建了網(wǎng)絡(luò)分析數(shù)據(jù)，，生成了網(wǎng)絡(luò)圖層，并在網(wǎng)絡(luò)分析中添加了道路的阻力值信息，同時通過arcEngine提供的相關(guān)類庫接口及路徑分析圖層，在系統(tǒng)中實現(xiàn)了路徑的動態(tài)規(guī)劃與顯示。 3、根據(jù)需求，對道路交通管理平臺進(jìn)行了總體設(shè)計，給出了數(shù)據(jù)庫詳細(xì)結(jié)構(gòu)，對模塊進(jìn)行了劃分，并采用ArcEngine的組件開發(fā)技術(shù)，以Microsoft visual studio為開發(fā)平臺，使用C#語言，實現(xiàn)了模塊的功能，實現(xiàn)了道路交通地理信息管理平臺的設(shè)計。 4、對論文工作進(jìn)行了總結(jié)，同時還指出了系統(tǒng)實現(xiàn)過程中存在的問題和目前功能方面的不足，明確了下一步研究工作的目標(biāo)。
[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.
