针对路径诱导过程中驾驶员的个性化需求,提出一种基于物理规划的路径诱导方法。首先,基于物理规划方法的基本思想,构建能够反映驾驶员个性偏好的路径诱导模型,包括构建路径评价的指标体系、设计偏好函数的数学表达式以及设计相应的偏好因子,为路径诱导提供了模型基础;然后,在构建交通路网数据库的基础上,通过设计合适的代价函数,利用A*算法搜索得到一条能够反映驾驶员个人偏好的最优路径。仿真结果表明:本文所设计的路径诱导方法能够满足驾驶员的个性化需求。

Aiming at the driver's individual demand during the route guidance process, a route guidance method based on physical programming was proposed. Firstly, guidance model which reflects the driver's individual demand well was constructed on the physical programming basic idea, which includes constructing the route evaluation index system, designing the preference function's mathematical expression and its corresponding preferred factors, providing the foundation model for the route guidance process. Secondly, an optimal route which reflects the driver's individual demand well was obtained by usin...
