驾驶人驾驶汽车进入隧道时,急剧改变的亮度环境将引起驾驶人产生视觉暗适应过程,造成"黑洞效应",严重降低驾驶人的视认能力,易导致交通事故的发生.因此,提出在隧道入口段铺设明色化的彩色路面来提高洞内亮度,进而缓解"黑洞效应"的不利影响,并通过实车试验获得驾驶人在原色、绿色、红色和黄色路面条件下的障碍物发现距离,定量评价驾驶人在彩色路面条件下的视认能力.结果表明:3种彩色路面对驾驶人的视认能力均有不同程度的改善,其中黄色路面改善效果最好.
Study of Driving Safety on Colored Pavement at Tunnel Entrance Section Based on Real Vehicle Measurements
When drivers enter a tunnel,the sudden change in luminance environment can cause visual dark adapta-tion,leading to the so-called"black hole effect,"which severely reduces drivers'visual recognition ability and easily causes traffic accidents.In view of this,this paper proposes laying brightly colored pavement at the tunnel entrance to increase the brightness in the tunnel,thereby mitigating the adverse effects of the"black hole effect."Real vehi-cle tests were conducted to quantitatively evaluate drivers'visual recognition ability under colored pavement condi-tions.The results show that the obstacle detection distances for drivers under original,green,red,and yellow pave-ment conditions distance are obtained through distance measurement tests,revealing that all three colored pave-ments improved drivers'visual recognition ability to varying degrees,with the yellow pavement showing the greatest improvement.
