摘　　要：针对目前虚拟应答器地图匹配采用直接投影法在复杂铁路路段上准确性差、匹配精度低的问题,该文提出了一种复合地图匹配算法。首先将铁路线路进行分段处理,然后根据所划分线路特征的不同,采用不同的地图匹配算法选取列车实际运行的匹配路段,最后进行仿真验证。通过与传统地图匹配算法进行对比,结果表明:在复杂路段下,复合地图匹配算法相对于传统地图匹配算法在匹配准确率上具有显著优势,具有较好的匹配效果,能够有效实现复杂路网下定位点的精准匹配,满足虚拟应答器的定位需要。In view of the problem of poor correctness and low matching precision of the current virtual balise map matching by direct projection method on complex railway sections,a composite map matching algorithm was proposed in this paper.Firstly,the railway lines were segmented,then the matching section where the trains actually travel was selected by different map matching algorithms according to the different characteristics of the segmented line,and finally the simulation was verified.By comparing with the classical map matching algorithm,the result showed that the composite map matching algorithm had a remarkable advantage over the classical map matching algorithm in terms of matching accuracy under the complex railway sections,which could effectively achieve accurate matching of localization points in complex railway networks to meet the localization needs of virtual balise.
