交通网络拥塞是一个具有理论意义和实际重要性的话题。在本文中，我们研究城市街道网络中的车辆流量。特别是，我们在复杂网络上使用元胞自动机模型来模拟车辆沿街道的运动，并结合街道交叉口的拥堵感知路由。这种路线利用代理对附近道路交通的了解，并允许车辆动态更新前往目的地的路线。通过在各个城市的真实城市街道模式中实施该模型，我们表明可以实现基于本地代理决策的全局交通优化。
Congestion in transport networks is a topic of theoretical interest and practical importance. In this paper we study the flow of vehicles in urban street networks. In particular, we use a cellular automata model on a complex network to simulate the motion of vehicles along streets, coupled with a congestion-aware routing at street crossings. Such routing makes use of the knowledge of agents about traffic in nearby roads and allows the vehicles to dynamically update the routes towards their destinations. By implementing the model in real urban street patterns of various cities, we show that it is possible to achieve a global traffic optimization based on local agent decisions.
