摘要
针对控制交通网络中所有节点存在成本较高的问题,在资源有限的情况下,构建城市交通网络分析与控制网络的牵制控制框架,提出了一种新的城市交通网络牵制控制算法。利用节点间的相互耦合和牵制关系,通过对路网中部分关键节点的控制,实现保障整个网络具有期望的行为,有效解决了系统所消耗计算、控制资源过多的局限性。将控制输入设置为绿灯时长的变化量,设计新的牵制控制器,并提出了有效保证城市道路交通网络稳定的条件。通过仿真分析,本文所提出的信号控制方法能够使得城市道路交通网络达到期望状态,并在基础设施和控制成本有限的情况下,有效提升道路资源利用率。
In view of the high cost of controlling all the nodes in the traffic network,a pinning control framework for urban traffic network analysis and control network in the case of limited resources were constructed by this paper,and a new pinning control algorithm for urban traffic network was proposed.By using the mutual coupling and containment relationship between nodes and controlling some key nodes in the road network,the expected behavior of the whole network was guaranteed,and the limitation that the system consumes too much computing and control resources were effectively solved.The control input was set as the variation of the duration of the green light,a new pinning controller was designed,and the conditions for effectively ensuring the stability of the urban road traffic network are proposed.Through the simulation analysis,the signal control method proposed can make the urban road traffic network achieve the desired state,and effectively improve the utilization of road resources in the case of limited infrastructure and control costs.
