| Abstract: | The real time traffic data is continuous and unbounded stream, while intelligent transport system needs to combine the traffic data with spatial information. From the view of data storage and query processing, traditional database techniques have the shortage for processing dynamic stream data and static spatial data simultaneously. A prototype system of a GIS based real time traffic monitoring is proposed based on the integration of existing data stream management system and spatial database management system. It supports historical one time query, continuous query and combine query, providing various and high quality services. |
