摘要:拥堵控制是在对交通物理系统中车辆运行状态感知的基础上,通过交通信息系统的分
析判断,作出相应的控制决策和操控驾驶行为的过程,具有信息物理融合系统的典型特征。
基于 Konishi 等的研究工作,考虑安全间距对交通流的影响,提出了一种基于耦合映射跟驰
模型的交通拥堵信息物理融合控制方法,仿真验证了该方法抑制拥堵的有效性。运用反馈控
制理论,给出了交通系统无拥堵条件,并与前人工作进行了比较。理论分析与数值模拟结果
一致表明,本文提出的控制方法能更有效地抑制交通拥堵的发生。

Abstract: Congestion control is a process to achieve optimal decision-making and effective
control of vehicles through the interaction of vehicular perception and control, and it shows the
typical characteristic of cyber physical systems. Based on the pioneer work of Konishi et al., a
new cyber-physical control method is presented to suppress the traffic jam in the coupled map
car-following model under open boundary condition. The effect of safe headway to the traffic flow
has been considered. According to the control theor
