摘　　要：本文旨在研究交通状况下驾驶员的视觉注意特性。根据实际交通状况下驾驶员的视觉注意行为设计了一种新型的交通环境驾驶仿真装置。通过实验,研究交通环境照度、驾驶速度和视觉注意转移方向对驾驶员反应时间的影响。结果表明,驾驶速度对视觉注意反应时间没有明显影响;年轻驾驶员的反应时间比年长驾驶员短,且受各种因素的影响不明显;对于年长驾驶员,黄昏时的视觉反应时间比白昼时长;视觉注意从近处转移到远处的反应时间比从远处转移到近处要长;但通过提示,预先告知在视觉深度转移方向时,反应时间可以缩短。The visual attention characteristics of drivers in traffic condition are studied in this paper. A no- vel traffic environment driving simulation device is designed according to the visual attention behavior of drivers in real traffic condition. Experiments are conducted to study the effects of traffic environmental illuminance, driving speed and the shifting direction of visual attention on the response time of drivers. The results show that driving speed has no obvious effects on response time; the response time of young drivers is shorter than that of aged ones and is less influenced by above-mentioned factors; For aged drivers, their response time is longer at dusk than that in daytime; Their response time when visual attention shifts farward is longer than that when visual attention shifts nearward; But if an advance notice is made by promting, the response time can be shorten.
