| 摘 要： | 地图匹配算法目的是将偏离道路的点纠正到正确位置上。本文基于传统的点到线的地图匹配算法，通过引入网格划分的概念来确认候选匹配道路，并且加权了方向因素来计算点到线的匹配程度。试验表明，改进后的算法能够提高其准确性，并且一定程度上提高了算法的效率，具有一定的实用价值。

| Abstract: | Map-matching algorithm is to correct the point that deviated from the road to the correct location.The candidate matching road is confired through leading the concept of grid division and the degree of matching about a point to a line is calculated through weighting factors of the direction based on traditional point-to-line map-matching algorithm.The test shows that the improved algorithm can improve the accuracy of the algorithm and the efficiency of the algorithm to a certain extent.This Algorithm has some practical value. |
