摘　　要：准确完整的交通矢量地图是车辆导航、路径寻优等应用工作的良好基础。为了解决交通矢量地图的错误数据信息问题,在分析城市道路分布特点的基础上,提出了一种基于道路知识的矢量地图数据校正方法。将矢量数据信息中普遍存在的错误进行分类,通过对城市道路设计规范和城市道路相关知识的归纳,抽取出对各种类型错误的判定规则和校正算法,为矢量地图的校正提供了一种较新的思路。实验结果表明,该算法能够快速有效的检测和校正矢量地图数据信息中存在的各类问题,能够保证矢量地图拓扑的准确性和完整性。The exact road information contained in vector maps is provided for different applications of intelligent vehicle navigation, optimal path founding, et al. An effective method for adjusting errors existing in vector maps is presented here. This method is based on the analysis of the distribution of city roads. Ordinary errors of vector maps are analyzed and categorized into several basic types. After concluding and analyzing the design criterion and the basic knowledge for city roads, this paper designs the judging rules for different errors, and puts forward a data-adjusting algorithms later. The experimental result shows that this algorithm is able to detect and adjust the three errors in vector maps effectively and quickly, thus enforcing the accuracy and integrality of maps.
