本文采用元胞自动机交通流模型对入口匝道系统进行研究。与以往的研究不同，本文不仅考虑了入口匝道流量对主干道的影响，而且考虑了入口匝道流量对主干道的影响。详细给出了更新规则，并引入了优先级的概念。进行了数值模拟，并给出了相图。区分了两种不同类型的相图，并讨论了入口匝道系统的电流。
In this paper, we study the on-ramp system using the cellular automata traffic flow model. Different from previous works, we consider not only the influence of the on-ramp flow on the main road but also the opposite influence. The update rules are given in detail and the concept of priority is introduced. The numerical simulations are carried out and the phase diagram is presented. Two different types of phase diagram are distinguished and the currents of the on-ramp system are discussed.
