Abstract:

为了研究驾驶人心理因素在信息认知过程中的作用机理,根据模糊数学和拓扑心理学原理,以数名驾驶人的驾驶信息为样本,分析了道路空间距离对驾驶人驾驶心理的影响程度,研究了在道路空间距离变化规律形成过程中,驾驶人心理量生成基础和变化原因。当实际道路空间距离分别为25、75、125m,车辆速度分别为0、20、40、60、80、100km/h时,进行了道路空间距离判识试验,并分别计算了在不同条件下的隶属函数模型。计算结果表明随着车速的增大,驾驶人的判识距离与道路实际空间距离的差值不断减小,下降速率不断增大;当车速大于40km/h时,随着道路实际空间距离的增大,判识距离下降速率逐渐减小;随着道路实际空间距离的减小,驾驶人心理疆域边界接触允许时间也在不断变小,碰撞风险增大。
