| 摘 要： | 针对城市道路网日益复杂的实际特点,提出基于P ign istic概率方法的地图匹配算法。采用D-S证据理论的多规则数据融合技术,建立了车辆位置信息和方向信息判决规则。引入P ign istic概率理论,有效地利用现有信息扩大各匹配道路之间的信度差异,提高了算法的鲁棒性。对实际行车数据仿真处理结果表明,应用该算法可以较好地解决城市复杂路网地图匹配问题。

| Abstract: | A map matching algorithm based on probability decision rule is proposed.The judging criteria for information on vehicle position and driving direction are established,using multi-rule data fusion technique based on Dempster-Shafer's evidence reasoning.By introducing Pignistic probability theory to expand the discrepancy in values of belief among various matching roads based on existing data,the robustness of algorithm is enhanced.The results of simulation on real driving data show that using this algorithm can better solved the map matching problem for complex road network in cities. |
