Inscribe the Exigency of Map Matching Performance for Curve Navigation on Road/Highways

摘要

GPS tracking data is essential for sensor data sources. It plays an important role in various systems like traffic assessment and prediction, routing and navigation, fleet management etc. The accuracy of data is an important issue, phenomena of sampling based vehicle movement with the existing GPS alerting systems. GPS navigation is not reliable because of two errors such as sources and continuous produce trajectory data.map matching algorithm finding a path between the points on the road network (graph) that minimizes frechet distance from a trajectory database. Therefore accurate data related to road network become essential for fast map matching algorithm. This work provides a technique to locate the frechet distance for path finding in available free space using adaptive map matching algorithm. We also adopt Dijkstra's path searching method with adaptive clipping for enhancing map matching process. This work also contribute to measuring frechet distance, map matching task, error estimation in trajectory data for reducing search space using adaptive clipping map matching algorithm for fast mapping process.
