| Abstract(in English) | In order to execute analytical processing for traffic control and traffic management effectively, we have been developing the spatial information systems for real-time location service. Our proposed system stores mobile location data using a spatial index, TPR-tree. At the same time, our system executes spatial queries for traffic estimation. In order to get results with high accuracy, our proposed system corrects measurement error of positioning data using road attributes in numerical maps. Based on real traffic data collected in Osaka city, we have simulation experiments to compare performance of "time-slice query, window query and moving query" executions. From the view points of the amount of data and number of queries, we make clear the performance of two architectures with different data correction steps. |
