摘要: 实际道路中前方车辆刹车灯会对后方车辆造成影响。在改进的刹车灯模型的基础上建立信号交叉口的元胞自动机模型,研究交通流速度、密度、排队长度及绿灯时长之间的关系;并与不考虑刹车灯模型时的信号交叉口元胞自动机模型进行对比分析。研究表明:考虑与不考虑刹车灯的影响,得到了相似的交通流速度、密度、排队长度及绿灯时长之间的关系,但刹车灯对信号交叉口交通流产生了影响,因此在信号交叉口交通流各种变量关系的分析中应考虑刹车灯的影响。

Abstract: The front vehicle’s brake lights would influence the rear vehicle on the actual road. Based on the improved brake lights model, a cellular automaton model of signalized intersections was established, and the relationships among the traffic flow speed, the density, the queue length and the green time were studied. The proposed model was compared with the one without consideration of brake lights. The research shows that considering the effect of the brake lights or not, the relationships among traffic flow speed, the density, the queue length and green time are alike. However, the traffic flow of signal intersection is affected by the brake lights, so the effect of brake lights should be considered in the analysis on the variables of the signalized intersection traffic flow.

Key words: traffic and transportation engineering, traffic flow, signalized intersections, cellular automata, green time, the queue length
