The invention discloses a dynamic path guiding method based on a traffic information physical system, which can reduce the vehicle passing time, improve the road passing capacity and more fully utilize road network resources, and provides a dynamic path guiding method by using Q-learning. According to the method, on the basis of comprehensively utilizing real-time road information (average passing time) and vehicle information (location and destination), rewards and a Q value table are dynamically updated, and an optimal path is given by utilizing a maximum value function according to a guiding mode and frequency. Finally, simulation verification is performed on the guiding method, so that the traffic capacity of the road network is effectively improved.

    本发明公开了一种基于交通信息物理系统的动态路径引导方法,能够减少车辆通行时间、提升道路通行能力、更为充分地利用路网资源,给出了一种利用Q‑learning进行动态路径引导方法,该方法在综合利用实时道路信息(平均通行时间)和车辆信息(所处位置和目的地)的基础上,动态更新奖赏和Q值表,并依据引导方式和频率利用最大化值函数给出最佳路径。最后对该引导方法进行了仿真验证,有效提高了道路网络的通行能力。
