单车道交通灯诱导的相变

Phase transition induced by traffic lights on a single lane road

A. Chacoma, M. N. Kuperman, G. Abramson

摘要:

在这项工作中,我们研究了交通信号灯系统对单车道道路流量的影响,提出了一个基于元胞自动机的交通模型,其中也包括行为的考虑。我们专注于系统的宏观表征,通过研究车辆密度的变化和堵塞的发生。在这种情况下,我们观察和表征之间的自由流动和堵塞状态的相变。这种转变是由车辆停在交通灯处引起的不稳定性引起的。此外,我们分析了这些不稳定性对临界车辆密度的影响,在临界车辆密度处,过渡发生为两个参数的函数:(i)汽车的流入,(ii)驾驶员的行为。对于后者,我们观察到,交通灯扰动反馈的司机的行为可以导致系统的不同的情况下,这也进行了分析。

英文摘要:

In this work we study the effect of a traffic light system on the flow of a single lane road by proposing a traffic model based on a cellular automaton that also includes behavioral considerations. We focus on the macroscopic characterization of the system by studying the changes in vehicle density and the occurrence of jams. In this context we observe and characterize a phase transition between the free flow and jammed states. This transition is induced by the instabilities originated by the vehicles stopping at the traffic lights. Moreover, we analyze the effect of these instabilities on the critical density of vehicles at which the transition occurs as a function of two parameters: (i) the in-flow of cars, (ii) the drivers' behavior. For the latter we observe that the traffic light perturbations feedback on the drivers behavior can lead the system to different scenarios, which are also analyzed.
