摘要
为了提高列车行驶过程中的定位精度,针对铁路轨道道路网较为简单的特点,给出一种针对不同轨道路段的地图匹配算法。根据铁路轨道数据信息建立相应的数学模型,并采用列车航向角和定位数据相结合的数学方法实现列车定位。通过北斗卫星采集到的数据试验,定位精度在10m内,证明了该算法的有效性,提高了定位的精确性。
A map matching algorithm which is aimed at simple train track for different track sections is presented in this paper.The corresponding mathematical models are established which are on the basis of railway track data,and the train positioning is realized by the combination of the train heading angle and the positioning data.According to the data collected by the BDS,the positioning accuracy is within 10 m.
