基于范例推理系统的实时道路交通行程安排研究

阐述了CBR的体系结构和开发过程。引用Virginia的hampron路径系统原型，说明了开发实时道路交通行程安排系统的方法与步骤。运用滚动视野法阶段性解决路径分配问题，反复进行路径分配方案的局部优化，使最新的环境信息得到充分利用。构建范例库的范例由一种用于地区的启发式的动态交通分配模型产生，用另外一组范例通过对比它和DTA模型的解来研究评估原型系统的性能。评估结果说明原型系统是能够在实时系统中运行的。

Research on Real-time Road Traffic Routing Arrangement of Case-based Reasoning System

The system architecture and development process of CBR are set forth in this paper. The means and approaches to develop real-time road traffic routing arrangement system are illustrated by using CBR, and road system prototype at Hampton in Virginia is quoted. A rolling horizon approach is utilized to solve the routing problem by stages, and the part routing strategy is optimized time and again in order to make the most of new circumstance informations. A set of CBR cases is produced by one kind of heuristic dynamic traffic assignment model which is used in that area, the performance of prototype system is studied and evaluated in contrasting them with dynamic traffic assignment model result by another set of cases. The evaluation result shows that the prototype system can run in real-time system.
