摘要

GPS技术精度不足，导致采样轨迹数据偏离实际道路。为了提高GPS轨迹数据与地图匹配的精度，提出了一种基于历史轨迹数据的地图匹配积分算法。首先分别使用投影距离和隐马尔可夫模型对匹配结果进行比较。然后找到不同路段，利用DBSCAN算法对历史轨迹数据进行聚类，调整路段;我们的实验使用卡车轨迹数据来测试算法。结果表明，地图匹配积分算法有效提高了地图匹配的精度。

Map Matching Integration Algorithm Based on Historical Trajectory Data

The insufficient accuracy of GPS technology leads to the sampling trajectory data being away from the actual road. In order to improve the accuracy of GPS trajectory data for matching to map, a map matching integration algorithm based on historical trajectory data is proposed. Firstly projection distance and hidden Markov model are used respectively to compare the matching results. Then the difference road segments are found and the DBSCAN algorithm is used to cluster the historical trajectory data to adjust the segments. Our experiment uses the truck trajectory data to test the algorithm. The results show that the map matching integration algorithm effectively improves the accuracy of map matching.
