摘　　要：采用心理测试软件在6个不同时段对5名驾驶员进行复杂反应实验,结合实验前后的主观疲劳,综合评估不同时段及实验过程对驾驶员心理疲劳的影响。分析表明,不同时段下驾驶员的复杂反应数据具有显著性差异,10:00最好,18:00次之,6:00、14:00和22:00较差,2:00最差,与主观疲劳基本符合;实验前后表现对比也具有显著性差异,在2:00变化最大。结果说明,驾驶员的心理疲劳程度受时段的影响较大,对安全驾驶具有参考意义。The aim of the study is to evaluate the effects of time of day variations on 5 driver＇ s psychological fatigue. In this study, 5 healthy drivers ran through a complex reaction test for 30 minutes at six period times of day. In addition, these drivers were asked to assess subjective fatigue before and after each session. The score of test varied significantly through the day, performance was best at 10：00, slightly fell at 18：00, more impaired at 6：00, 14：00 and 22：00, worst at 2：00, which was almost the same as the score of subjective fatigue. The scores were also decreased along with the procedure of the test at different period time, of which the contrast of score at the beginning and at the end of 2：00 is the most distinct. These results suggest that psychological fatigue of drivers is subject to time of day variations, and might be helpful for driving safety.
