The invention discloses an urban traffic network containment control method, and belongs to the technical field of urban traffic network control. According to the method, a CTM-based discrete time urban road traffic network model is established; for solving the problem of urban road traffic jam, a containment control idea of a complex network is applied to urban road traffic analysis and control.The invention further designs a containment controller. A control strategy for stabilizing the traffic flow of the road section is provided; the stability of the controlled system is analyzed by taking the variable quantity of the green light duration as control input, and the stability condition of urban road traffic network containment control is given, so the whole controlled network is synchronized, the road section flow is stabilized near an expected value, the control cost is reduced, and the problem of urban road traffic congestion is better solved.
本发明公开了一种城市交通网络牵制控制方法,属于城市交通网络控制技术领域,该方法建立了基于CTM的离散时间城市道路交通网络的模型,针对城市道路交通堵塞问题,将复杂网络的牵制控制思想应用于城市道路交通分析与控制中,本发明还设计了牵制控制器,并给出了使路段车流量稳定的控制策略,将绿灯时长的变化量作为控制输入,对受控系统的稳定性进行了分析,给出了城市道路交通网络牵制控制的稳定性条件,使得整个受控网络达到同步,使得路段流量稳定在期望值附近,降低了控制成本,更好地解决了城市道路交通拥堵问题。
