The Design And Implementation Of Urban Road Traffic Management Of Spatial Database

ITS (Intelligent Transport System) is the important way of solving the problem of urban traffic congestion, on urban road traffic management Department of management objects, both infrastructure and traffic management facilities have strong spatial characteristics, establishment of a unified, complete, open spatial database to support the ITS is inevitable. At home, its has been emphasizing that intelligent traffic management means, ignore the traffic information services, and domestic cities at different times, to different target construction of ITS different classifications, effects associated lack of associated factors of urban traffic. Ultimately, difficult to combined effects of urban transport in the urban traffic management sector for integrated traffic management decisions.This, for Kunming Public Security Bureau traffic police detachment ITS application needs, to Kunming police command center business and traffic related data for research object, by participation police command center business, analysis traffic Foundation facilities data and traffic management facilities data, using geographic information system technology established history data full, and integrated has built system data of traffic spatial database, implementation on more source traffic related information of integrated management and analysis, for traffic management command provides integrated, and integrated, and collaborative of analysis decision support, This major work includes:1. discussion has space database in the-oriented object data model on space data of organization and management, on typical of application model Geodatabase and application schema mode Arc SDE Geodatabase for analysis;2. analysis discussion has with UML for space database built die in the UML of built die mechanism, and built die process and built die policy.3. data for urban traffic management and business, combined with the spatial database design principles, elaborated spatial database design of urban road traffic management hierarchical organizational thought processes and data.4. combination of needs and business situation of Kunming City Public Security Bureau police detachment, using UML tool based on ESRI ArcGIS10and Microsoft SQL Server2008spatial database design in Kunming city road traffic management, derived from the database used to support development of the Kunming city road traffic information visualization platform.
