Paper Abstract

Intelligent Transportation System (ITS) is a valid utility to solve the problem of heavy traffic and ensuring safety of traffic and transportation, especially in large city, e.g. Beijing. A WebGIS system functioning to provide real-time road condition information was developed in this paper. In order to ensure the logic and reliability of data management, a uniform GeoDatabase space database was established based on these three factors as below: the difference of travel volume in different time and road, real time dynamic updating traffic database, and the traffic space dataset in Beijing. In this GeoDatabase the right connectivity of multi-layer data was investigated. In the shortest road search routine, some parameters, such as traffic flow and the length of cond path, which may be concerned by many users, were used as weights to determinate an optimal road. The dynamic updating data could be stored in the database in the format of GeoDatabase, the quantitive research to determine the optimal weight coefficient of travel carrying capacity could be available through proper traffic model and real time dynamic updating data. Besides, the final traffic model would be formed considering the length of optimal path. This intelligent transportation WebGIS inquiry system is developed on base of Visual Studio.NET and Arcgis Server platform. The system would publish data through Web server and supply clients with the service to inquire the real time optimal travel path in Beijing.
