浮动车地图匹配算法能够实现浮动车离散点与路段的快速准确匹配,是浮动车路况信息生成技术中的核心环节。本文针对现有方法的不足,实现了建立定位点的有效阈值缓冲区,并依据空间关系检索候选匹配路段,研究实现了一种利用行驶速度、行驶方向、投影距离、行驶距离4个参数进行行车轨迹判别的逻辑匹配算法。试验表明,该方法无需对路网数据进行大量的前期处理工作,简化了候选匹配路段的检索过程,在保证匹配正确率的同时也表现出了更高的效率。
Floating vehicle map matching algorithm can realize fast and accurate matching between discrete points and sections of floating vehicles, which is the core link of floating vehicle traffic information generation technology. In order to overcome the shortcomings of the existing methods, an effective threshold buffer is established and the candidate matching sections are retrieved according to the spatial relations. A driving force, driving direction, projection distance and distance traveled are studied in this paper. Logistic Matching Algorithm of Logic Matching. Experiments show that this method does not require a lot of preprocessing work on the road network data, simplifies the retrieval process of candidate matching segments, and also shows higher efficiency while ensuring the matching accuracy.
