驾驶人空间距离判识规律心理学分析

Analysis on psychology in cognitive distance about drivers

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。

The principles of fuzzy mathematics and topological psychology were used to study the mechanism of psychological factor for driver during the information cognitive process.The driving information of several drivers were taken as samples,the influence degree of road space distance on the driving psychology of driver was analyzed,and the generation basic and change reason of driver were researched during the forming process of changing law for road space distance.When the actual road space distances were 25,75,125 m respectively,and the vehicle speeds were 0,20,40,60,80,100 km·h-1 respectively,the identification test of road space distance was carried out,and the membership function models were calculated respectively under different conditions.Calculation results show that with the increase of vehicle speed,the difference between identification distance of driver and actual road space distance decreases continuously,the decreasing rate increases continuously.When the vehicle speed is more than 40 km·h-1,with the increase of actual road space distance,the decreasing rate of identification distance decreases continuously.With the decrease of actual road space distance,the allowed contact time of psychological territory boundary for driver also decreases continuously,and the collision risk increases.
