Description

Local Dynamic Map(LDM) has been studied for ITS Cooperative Systems. The LDM is a hierarchical system that manages driving environment recognition information sent from vehicle on-board sensors and through vehicle-to-vehicle communications or map data. We have proposed "Stream-LDM" using Data Stream Management System (DSMS) to realize high response. However, we found processing time for map data on data base to be performance bottlenecks. In this paper, we describe that this problem is resolved by Map Data Processing Mechanism which makes it possible to process static map data in DSMS. By Evaluation using vehicle driving simulation, we confirmed that the average performance of spatial operator for map data to be improved several 10 times as much as the conventional methods.
