摘要:

在安全运行约束下,为了分析公路隧道照明需求,提出公路隧道环境亮度安全临界阈值.构建模拟隧道环境识别实验,设计动、静2种实验模式,通过对7 020余组人眼识别时间与环境亮度实验数据的统计分析,得出环境亮度与人眼反应时间呈幂指数关系.在此关系基础上,结合驾驶员信息感知识别时间要求,得出公路隧道环境亮度安全临界阈值.选择长、中、短隧道进行实验,结果表明,隧道环境亮度安全临界阈值为5 cd/m2,远低于国际照明学会(CIE)隧道适应曲线所推荐的值,可大幅简化和降低公路隧道照明设置,节约照明运营成本.

Abstract:

To analyze the highway tunnel’s lighting in safe driving conditions, security critical threshold of the environment brightness is given. The tunnel brightness environmental recognition experiments and two kinds of experiments models, the dynamic and static ones, were designed. Base on more than 7 020 experimental data, an exponential law was found between the environment brightness and human eyes response time. Combining the driver’s traffic information identification time, the security critical threshold of the environment brightness is got. Furthermore, sources from the engineering data of three highway tunnel, long, middle and short respectively, a conclusion of the security critical threshold of the environment brightness is 0.5 cd/m2, and 0.5 cd/m2 is much less than the values recommended by the CIE adaptation curve, so the highway tunnel lights can be greatly simplified and lowered.
