多路段交通元胞自动机的亚稳态拥塞状态
Metastable Congested States in Multisegment Traffic Cellular Automaton
摘要：
研究了一个简单的多段元胞自动机交通流模型。引入段相关减速概率，在中密度区域出现亚稳态拥塞状态，并观察到流的初始状态依赖性。在没有详细假设的情况下，再现了在现实世界的交通流中经验发现的三相结构的基本特征。
英文摘要：
We investigate a simple multisegment cellular automaton model of traffic flow. With the introduction of segment-dependent deceleration probability, metastable congested states in the intermediate density region emerge, and the initial state dependence of the flow is observed. The essential feature of three-phased structure empirically found in real-world traffic flow is reproduced without elaborate assumptions.
