摘　　要：路网匹配一直是路网数据更新和变化发现的关键技术。针对用"弧段—结点"模型表达的路网数据,设计了stroke生成方法,对路网进行了stroke生成,并根据stroke长度进行了等级划分。在等级划分的基础上,提出了基于stroke分级的路网匹配算法。通过仿真验证,该匹配算法对研究数据进行stroke匹配的正确率达到91.4%,能得到较好的匹配效果。The road network matching is always the key technique to find road updating and changing. Based on the ＂arc-node＂ road network data model, a stroke-generating method is designed and the road network is stroke-generated. And according to the length of the stroke, the strokes are classified. Upon the basis of the classification, a road network matching algorithm is proposed. Through the simulation test,the matching algorithm is found to be able to get the desirable matching results,with the correct rate of the stroke matching being up to 91.4~.
