城市道路环境中驾驶人应激判断决策的时间特性

Time Characteristics of Drivers' Emergency Response Judgment Decision under Urban Road Environment

针对驾驶人在城市道路环境中的应激判断决策时间进行了虚拟驾驶试验,统计了不同被试的判断决策时间,分析了该时间与驾驶经验、年龄、车速之间的相关性.结果表明,熟练驾驶人的判断决策时间要略大于非熟练驾驶人,且属中年人最为稳定.应激决策时间随着车辆速度的增加,而逐渐减小.此外,应激决策反应时间可以通过驾驶人的驾驶经验、年龄以及行车速度来综合进行预测.

Virtual driving tests have been done to obtain drivers＇ emergency response judgment decision time in urban road environment.By statistical different drivers＇ judgment decision time,the correlations between drivers＇ judgment decision time and driving experience,age,speed are analyzed.The results show that experienced driver＇s judgment decision time is longer than that of un-experienced drivers,and the middle age driver＇s decision time is most stable.With the increasing of vehicle speed,driver＇s emergency response judgment decision time is declined relatively.Besides,the forecast model based on driver＇s experience,driver＇s age and vehicle speed can predict the judgment decision time correctly.
