【摘要】 公路交通中的酒后驾驶、疲劳驾驶或其他不良驾驶行为会直接导致驾驶员的反应迟钝,极易酿成重大的交通事故.本文着重研究了驾驶员反应时间对行车安全的影响.首先,基于NaSch模型提出了一种能模拟驾驶员驾驶行为对行车安全影响的元胞自动机模型.其次,通过数值模拟给出了反应时间对交通安全影响的曲线.研究发现驾驶员的反应时间是影响行车安全最重要的因素之一.最后,本文试图提出一种降低风险的策略.研究结论是:杜绝酒后驾驶、疲劳驾驶等不良驾驶行为是保证行车安全的重要措施.更多还原

【Abstract】 In highway traffic, drink driving, fatigue driving and improper driving directly lead to the drivers’ slow reaction and easily cause major accidents. Effects of driver’s reaction time on safe driving are studied. Firstly, On the basis of NaSch model, a cellular automaton model that can simulate effects of driver’s reaction time on safe driving is proposed. Secondly, the curve between reaction time and traffic safety is obtained from numerical simulation. Results show that the driver’s reaction time is one of the most important factors affecting the traffic safety. Finally, a strategy of risk reduction is put forward. It is an important measure for safe driving to eradicate drink driving, fatigue driving and improper driving.更多还原
