摘　　要：驾驶员在愤怒时的驾驶行为表现与正常驾驶时存在较大的差异,这些行为差异会影响车辆的运行速度、运行轨迹等,进而对道路交通流产生影响.文中在NaSch元胞自动机交通流模型的基础上,考虑愤怒驾驶行为的特点,从运行速度、换道条件和安全距离3个方面重新确定元胞更新规则,构建考虑驾驶愤怒情绪的周期边界条件下双车道元胞自动机交通流模型.在MATLAB环境下,对所建模型与普通NaSch交通流模型进行对比仿真分析.结果表明,驾驶愤怒所引起的行驶速度变化对交通流影响明显.Driving behaviors of the angry drivers are quite different from those of the normal drivers.Because of these behavioral differences,driving speed,driving track etc.can be influenced,resulting in a different state of the road traffic flow.This paper re-defined the typical cellular automaton updating rules in mainly three aspects,i.e.,speed,lane change conditions as well as the safe distance and established the periodic boundary two-lane cellular automata traffic flow model considering the characteristics of angry driving behaviors based on NaSch cellular automaton traffic flow model.Both the model constructed and the classical NaSch traffic flow model were simulated in MATLAB and the comparison show that the variance in speed caused by driving anger had the most significant impact on traffic flow.The research can provide as the guidance on establishing models for cellular automaton traffic flow with consideration of driving anger and studying the influence of it to the urban traffic flow;the influence on traffic flow of other driver concerned factors,e.g.,driving fatigue,driving distraction need further research following this method.
