在交通系统中，合理的信息反馈可以提高道路通行能力。在本文中，我们研究了一种非对称的两路场景，在该场景中，动态信息可以被生成并显示在黑板上，以引导司机。介绍了两种改进的反馈方式，即改进的平均速度反馈和改进的拥塞系数反馈。仿真结果表明，平均费用依赖于车辆到达率，且存在一个与最大流量对应的动态车辆比的临界值。结果表明，改进的编码系数比改进的平均速度反馈能更好地提高系统容量。
In traffic system, a reasonable information feedback can improve road capacity. In this paper, we investigate an asymmetrical two-route scenario in which dynamic information can be generated and displayed on the board to guide drivers. Two improved feedbacks (i.e. improved mean velocity feedback and improved congestion coefficient feedback) are introduced. Simulations show that the average cost is dependent on the vehicle arrival rate and there exists a critical the dynamic vehicles ratio corresponding to the maximum flux. We find that improved con-gestion coefficient can better enhance the system capacity than that of improved mean velocity feedback.
