高速公路上的交通流动和互联网上的数据包传输是复杂系统中集体动力学行为的典型例子。尽管增强复杂网络中交通流的研究已被广泛开展，但大多数现有研究集中于单队列模型。本文提出了一种简单而有效的双队列方案，通过门控来调节车辆进入，并将其与路由协议相结合。当车辆到达匝道门时，它们首先加入等待队列，并允许在主流动队列清空后进入。这种双队列策略在高速公路流入量随大波动周期性变化时尤为有利，这在真实交通中很常见。此外，它改变了系统的失效特性，将突然的、不连续的堵塞转变替换为渐进的、连续的转变。该方法基于仅使用局部队列信息的简单规则，易于实现且适用广泛。除了本文研究的特定设置外，它还可以应用于不同条件下的其他交通网络，或扩展到其他排队系统，如互联网数据包路由。
英文摘要
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.
