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。
Using the speed perception tester, the speed estimation accuracy of 251 male truck drivers under four experimental conditions was measured. The results showed that the accuracy of speed estimation of truck driver in safety group was better than that of truck driver in accident group, the difference was not significant under low speed condition, and the difference was significant under high speed condition. There was no significant difference between the driver and the truck driver at low speed, but the difference was significant under the high speed condition. The accuracy of the speed estimation of the truck driver with multiple accident and safety groups was significant at high speed and low speed and long distance conditions. There was a significant interaction between the two variables. Age had no significant effect on the accuracy of velocity estimation.
