The aim of this work is to investigate the coordinated control of urban expressway integrating adjacent signalized intersections based on pinning synchronization of complex networks. An expressway network integrating adjacent signalized intersections was used as the studied object, where no signal light is set on ramps and ramp metering is achieved only through the use of signal lights at adjacent intersections. An improved cell transmission model (CTM) for each segment of the studied object, comprising a mainline, an on-ramp, an off-ramp, side roads, and adjacent intersections, was established. Each node of the system was defined, and a node coupling model integrating adjacent signalized intersections was also established. The coordinated controller was designed, with the signal timings of adjacent intersections used as decision variables. Using the stability theory of complex networks, the concrete pinning nodes corresponding to the subsystems of regulating the inflow from on-ramps adjacent intersections to mainline could be obtained, and the signal timing schemes at intersections could be optimized. The outflow from the mainline to off-ramps adjacent intersections could be appropriately regulated in order to mitigate off-ramp congestion. The proposed method was validated through simulation experiments. The results indicate that the traffic jam phenomenon can be suppressed utmost, off-ramp congestion can be mitigated, and the operational efficiency can be enhanced at minimal control cost.

这项工作的目的是研究基于复杂网络钉扎同步的，集成了相邻信号交叉口的城市高速公路的协调控制。集成了相邻信号交叉路口的高速公路网络被用作研究对象，其中没有在坡道上设置信号灯，仅通过在相邻交叉路口使用信号灯来实现匝道计量。建立了针对研究对象的每个部分的改进的小区传输模型（CTM），包括主线，匝道，匝道，小路和相邻的交叉路口。定义了系统的每个节点，并建立了一个包含相邻信号交叉口的节点耦合模型。设计了协调控制器，将相邻交叉口的信号时序用作决策变量。利用复杂网络的稳定性理论，可以得到对应于调节从匝道上相邻交叉口到干线的入流子系统的具体钉扎节点，并可以优化交叉口的信号定时方案。可以适当地调节从干线到坡道相邻交叉口的流出量，以缓解坡道拥堵。仿真实验验证了该方法的有效性。结果表明，可以最大程度地抑制交通拥堵现象，可以缓解匝道拥堵，并以最小的控制成本提高运营效率。交叉口的信号时序方案可以优化。可以适当地调节从干线到坡道相邻交叉口的流出量，以缓解坡道拥堵。仿真实验验证了该方法的有效性。结果表明，可以最大程度地抑制交通拥堵现象，可以缓解匝道拥堵，并以最小的控制成本提高运营效率。交叉口的信号时序方案可以优化。可以适当地调节从干线到坡道相邻交叉口的流出量，以缓解坡道拥堵。仿真实验验证了该方法的有效性。结果表明，可以最大程度地抑制交通拥堵现象，可以缓解匝道拥堵，并以最小的控制成本提高运营效率。
