摘要
高速公路隧道进出口亮度的急剧变化,直接影响驾驶行为,甚至导致交通事故.利用照度仪、加速度采集仪、EMR-8B眼动仪等设备,通过对隧道进出口驾驶员的瞳孔变化等进行大量行车实验和分析证明,隧道内距进出口50 m范围,驾驶员瞳孔面积与隧道进出口照度成幂函数关系,驾驶员瞳孔面积变化速度可作为隧道进出口的行车安全评价指标.统计分析表明,基于行车安全的驾驶员瞳孔面积变化临界速度在-6 mm2s-1到4 mm2s-1之间,研究还得出了基于视觉适应的隧道进出口照明公式.
Luminance＇ s sharp variation when driving through the freeway tunnel＇ s entrance and exit will engender driver＇ s behaviors, even lead to traffic accident. Analysis was concucted by using illumination meter, acceleration collection meter, EMR -8B system,etc, based on many experiments of driver＇s pupil variety during freeway tunnel＇ s entrance and exit. The analysis results presented that driver＇ s pupil area had power functional relationship with road illuminance at the distance of 50 m to the tunnel＇s entrance and exit, and driver＇s variety velocity of pupil area could be taken as evaluation index of driving safety when driving through the freeway tunnel＇s entrance and exit. The statistical analysis also indicated that variety velocity of pupil area should be between -6 mm^2/s and 4 mm^2/s based on driving safety. Furthermore, rational luminance formula of tunnel＇s entrance and exit was elicited based on visual adaptation.
