Excessive cold or overheating can cause a decline in driver performance and even serious traffic accidents, but the influence mechanism of ambient temperature and vehicle speeds on drivers' cognitive performance is still unclear. This research developed an easy driving simulator experiment to study driver performance under different ambient temperatures and vehicle speeds.
Simulated driving tasks were performed by 30 male participants at different speeds in low, medium, and high-temperature environments. A behavioral experiment was adopted, and the average reaction time of emergency braking was used as the evaluation index of driver performance.
Both ambient temperature and vehicle speed had a statistically significant relationship with driver's braking reaction time, and the interaction effect was significant.
Drivers' cognitive efforts in medium-temperature environments were significantly lower than that at high and low temperatures. Compared with previous studies, this study also monitored differences in the activity of drivers' brain regions in three ambient temperatures, providing a physiological basis for measuring drivers' cognitive efforts.
过冷或过热会导致驾驶员操作能力下降，甚至引发严重交通事故，但环境温度和车速对驾驶员认知能力的影响机制尚不清楚。本研究开展了一项简易驾驶模拟器实验，以研究不同环境温度和车速下的驾驶员操作能力。
30名男性参与者在低温、中温和高温环境下以不同速度进行模拟驾驶任务。采用行为实验，将紧急制动的平均反应时间作为驾驶员操作能力的评估指标。
环境温度和车速与驾驶员的制动反应时间均存在显著的统计学关系，且交互作用显著。
驾驶员在中温环境下的认知努力明显低于高温和低温环境。与以往研究相比，本研究还监测了三种环境温度下驾驶员脑区活动的差异，为衡量驾驶员的认知努力提供了生理依据。
