高速公路上的车辆移动与互联网中的数据分组传输是复杂系统中集体动力学行为的典型范例。尽管增强复杂网络中的交通流已被广泛研究，但现有大多数研究集中于单队列模型。本文提出了一种简单而有效的带有门控机制的双队列方案，该方案调控车辆进入并与路由协议相结合。当车辆到达匝道入口时，首先加入等待队列，并在主流动队列清空后被允许进入。这种双队列策略在公路流入量呈现大幅波动的周期性变化时尤为有利，这在真实交通中十分常见。此外，它改变了系统的失效特性，将突然、不连续的拥堵相变转变为渐进、连续的相变。该方法基于仅利用局部队列信息的简单规则，易于实现且具有广泛的适用性。除了本文研究的具体场景外，该方法还可应用于不同条件下的其他交通网络，或扩展至其他排队系统，如互联网数据分组路由。

Traffic movement on highways and data packet transmission across the Internet serve as prototypical examples of collective dynamical behavior in complex systems. Although enhancing traffic flow in complex networks has been extensively investigated, most existing studies focus on single-queue models. In this paper, we introduce a simple yet effective two-queue scheme with gate control that regulates vehicle entry and integrates it with the routing protocol. When vehicles arrive at a on-ramp gate, they first join a waiting queue and are permitted to enter the main flowing queue once it has emptied. This two-queue strategy is especially advantageous when highway inflow varies periodically with large fluctuations, as is commonly observed in real traffic. Moreover, it modifies the system's failure characteristics, replacing sudden, discontinuous jamming transitions with gradual, continuous ones. The approach is based on a simple rule using only local queue information, making it easy to implement and widely applicable. Beyond the specific setup studied here, it can be applied to other transportation networks under different conditions or extended to other queuing systems, such as Internet data packet routing.
