卡车驾驶员速度估计研究

用速度知觉测试仪，对251名男性卡车驾驶员在四种实验条件下的速度估计准确性进行了测量。结果发现：安全组卡车驾驶员的速度估计准确性优于事故组卡车驾驶员，两者在低速条件下差异不显著，高速条件下差异显著;事故组卡车驾驶员的高估次数高于安全组卡车驾驶员，低速条件下两者不显著.高速条件下差异显著;事故多发组与安全组卡车驾驶员的速度估计准确性在高速及低速长距离条件下差异显著;速度及距离对速度估计准确性有显著影响，且两者之间存在显著的交互作用;年龄对速度估计准确性无显著影响。

A STUDY OF TRUCK DRIVERS' SPEED ESTIMATION

An experiment was conducted under 4 conditions on the estimation of speed by means an instrument of speed perception. The subjects were 251 male truck drivers. The results in,licated: 1 ) The accuracy in speedestimation of safe truck drivers was better than that of accident truck drivers. The difference was significant only in high-speed conditions. 2) The number of overestimation in accident drivers was greater than that of safe drivers. The difference was significant only under high-speed conditions. 3) The difference of the accuracy in speed estimation between accident repeaters and safe drivers was significant under the conditions of high-speed, lowspeed and long-distance. 4) Speed and distance had significant impact on drivers' speed estiamtion. The interaction between them was significant. 5) Age had no significant influence on drivers' speed estimation.
