交通信号控制面临的一个主要挑战是适应不可预测的交通变化。为了解决这个问题，我们提出了一个自主分散控制方案的交通信号，是基于物理。更具体地，通过使用最佳速度模型在每个交通信号处计算由红色信号或前面的汽车给出的“虚拟脉冲”，其以与物理学中通常使用的脉冲类似的方式定义，并且交通信号被切换以减少这些虚拟脉冲。我们在各种交通条件下进行了模拟，结果表明，所提出的控制方案的工作自适应和弹性的情况下，每一组。因此，虚拟脉冲可以是设计自适应交通系统的关键物理量。
A major challenge for traffic signal control is adapting to unpredictable changes in traffic. To address this issue, we propose an autonomous decentralized control scheme for traffic signals that is based on physics. More specifically, “virtual impulses” given by red signals or preceding cars, which are defined in a similar manner as the impulses generally used in physics, are calculated at each traffic signal by using an optimal velocity model, and traffic signals are switched to reduce these virtual impulses. We performed simulations under various traffic conditions, and the results showed that the proposed control scheme works adaptively and resiliently in response to each set of circumstances. Thus, the virtual impulse can be a key physical quantity for designing adaptive traffic systems.
