基于物理规划的思想,研究面向驾驶员个性化需求的动态路径诱导方法。首先,分析个性化动态路径诱导问题,构建路段交通阻抗的个性化评价指标体系;然后,基于物理规划思想,进行个性化动态路径诱导:面向驾驶员对道路的"可行性"需求动态确定交通路网搜索的几何空间;面向驾驶员对道路的"偏好性"需求,对几何空间内的交通路网阻抗进行个性化评价;面向驾驶员对道路的"最优性"需求,基于Dijkstra算法在动态交通路网中进行最优路径搜索;当路网中的交通阻抗发生变化时,及时更新路网信息,重新搜索从车辆当前位置到目的地的最优路径。研究结果表明:该方法既能体现驾驶员的个性化需求;仿真算例验证了该方法的有效...

A dynamic route guidance method facing the driver's individual demand was advanced based on physical programming theory. Firstly, the personalized dynamic route guidance problem was analyzed and the individualized evaluation index system of road traffic impedance was constructed. Then, based on physical programming theory, the method of individual dynamic route guidance was studied as follows: Aiming at the driver's feasibility demand on the road, the dynamic traffic road network geometry space for searching was determined. Aiming at the driver's preference demand on the road, the evaluation o...
