在交通系统中,一种合理的信息反馈能够缓解交通拥堵,提高道路的通行能力.运用两种改进的信息反馈(改进的平均速度反馈和改进的拥挤系数反馈)研究了非对称的双通道交通系统.模拟结果显示,出行者平均出行时间与入口处车辆到达概率有关:当到达概率较小时,采用改进的平均速度反馈能节省出行时间;当达到概率较大时,采用改进的拥挤系数反馈更能节省出行时间.另外还考察了系统中动态车比例、道路上瓶颈位置、瓶颈长度及道路长度等参数,发现改进的拥挤系数反馈能够更好地提高道路的通行能力.
In the transportation system, a reasonable information feedback can alleviate traffic congestion and improve the capacity of the road.Using two improved information feedback (improved average speed feedback and improved crowding coefficient feedback) studied the asymmetric two-lane traffic System.The simulation results show that the average travel time of travelers is related to the arrival probability of vehicles at the entrance: when the probability of arrival is small, using improved average speed feedback can save travel time; when the probability of arrival is greater, the improved congestion coefficient feedback Which can save travel time.In addition, the dynamic car ratio, bottleneck position, bottleneck length and road length in the system are also investigated. It is found that improved congestion coefficient feedback can better improve the capacity of the road.
