摘　　要：利用手机获取位置数据在采样点数量、覆盖率、开销等方面具有优势,但在位置数据的处理上,现有的地图匹配算法大多应用于GPS定位,在手机定位上应用较少,同时在算法测试上也大都采用模拟数据进行,缺乏真实数据的检验。针对这一问题,为了检验算法在真实数据中的运行情况以及能否应用于手机定位,在用手机采集大量定位数据的基础上,对算法分别用采集的GPS定位数据和手机基站定位数据进行了检验。结果表明,算法在手机GPS位置信息上应用较好,在处理手机基站位置信息时匹配精度不稳定。实验结果表明,提高采样频率可以提高手机基站定位精度。Using mobile phone has an advantage of obtaining location data in the number of sampling points,coverage,cost and other aspects. However,in dealing with the position data,most of the existing map-matching algorithms are applied to the GPS positions,and most of the algorithms are tested using simulated data. In order to find the running condition in real data and the usability on mobile phone,a Hidden Markov map matching algorithm was tested by GPS positioning data and mobile phone location data in this paper. The results show that,the algorithm work well on cell phone GPS positions. And it also can run on location information of mobile phone base station,but the accuracy of map-matching is unstable. The experimental results show that,increasing the sampling frequency can improve the positioning accuracy of mobile phone base stations.
