考虑公交港湾式停靠的多速混合城市交通流元胞自动机模型研究

在Nagel-Schreckenberg提出的元胞自动机模型基础上，建立了考虑公交车辆和港湾式公交停靠站的多速混合车辆单车道城市交通流元胞自动机模型.通过计算机模拟，给出了随机减速概率、混合车流密度、公交车辆平均停靠时间、公交车辆占有率和港湾式公交车站间距对混合车流速度和流量的影响图.对混合车流的特性进行了分析和讨论. 关键词： 元胞自动机 港湾式公交停靠站 混合交通流模型 计算机模拟

The study of a cellular automaton traffic flow model with public transit, harbor-shaped bus stop and mixed different-maximum-speed vehicles on single lane

Based on the Nagel-Schreckenberg models of traffic flow， a cellular automaton traffic model with different-maximum-speed vehicles mixed on single lane is proposed， which considers public transit and harbor-shaped bus stop. The influence of deceleration probability， the density of vehicles， the average stop time of public transit vehicles， the proportion of public transit vehicles occupied in the mixed vehicles and the bus stop spacing on mixed traffic flow are analyzed by computer simulation. The models traffic flow characters are presented and analyzed.
