To prevent vehicle crashes, studies have proposed the use of flashing signals (brake lights or other light indicators) to improve the driver's response time when the leading vehicle is braking. However, there are no consistent results on the ideal flashing frequency of the brake lights. This study aimed to investigate different brake light flashing frequencies to assess their impact on braking response time. Twenty-four participants aged 25 to 30 were recruited. Two driving speed environments (50 and 80 km/h), three deceleration rates (0.25, 0.6, and 1 g), and four brake light flashing frequencies (0, 2, 4, and 7 Hz) were examined. Braking response time, average braking force, and braking response time ratio were used to evaluate the driving behavior. The results showed that the braking response time and average braking force were affected by the deceleration rate in the 50 km/h driving environment. In the 50 and 80 km/h driving environments, although there were no significant differences among the three deceleration rates, the braking response time decreased by 3-7% under the flashing brake light condition. These findings can be used as a reference for safety designs as well as future studies on driving behavior.
为预防车辆碰撞事故，研究提出使用闪烁信号（刹车灯或其他灯光指示器），以在前方车辆制动时缩短驾驶员的反应时间。然而，关于刹车灯的理想闪烁频率，尚未得出一致的研究结果。本研究旨在探究不同的刹车灯闪烁频率，以评估其对制动反应时间的影响。招募了24名年龄在25至30岁之间的参与者。研究考察了两种驾驶速度环境（50和80公里/小时）、三种减速度（0.25、0.6和1g）以及四种刹车灯闪烁频率（0、2、4和7赫兹）。采用制动反应时间、平均制动力和制动反应时间比来评估驾驶行为。结果表明，在50公里/小时的驾驶环境中，制动反应时间和平均制动力受减速度的影响。在50和80公里/小时的驾驶环境中，尽管三种减速度之间没有显著差异，但在刹车灯闪烁的情况下，制动反应时间缩短了3%至7%。这些研究结果可为安全设计以及未来的驾驶行为研究提供参考。
