摘　　要：针对公路隧道照明节能研究中较少考虑照明方式与小目标可见度之间关系的现状,通过隧道照明仿真实验,分别得到逆光照明、对称照明和顺光照明条件下中间段的路面平均亮度、亮度总均匀度、车道中线亮度纵向均匀度等指标值,并探讨了3种照明方式下的小目标可见度取值情况。结果表明,逆光照明时阈值增量TI值最高,顺光照明时小目标可见度STV值最高。The relationship between tunnel lighting modes and small target visibility(STV)was poorly considered in the current research on energy-saving of highway tunnel lighting.The tunnel lighting modes include counter-beam lighting,symmetrical lighting and pro-beam lighting.Through tunnel lighting simulation experiments,this paper aimed to obtain the road surfaceaverage luminance,the total uniformity of luminance and the longitudinal uniformity of the middle lane luminance under the three tunnel lighting modes.Meanwhile,the small targetvisibility was discussed under the counter-beam lighting,symmetrical lighting and pro-beam lighting.The results showed that the value of threshold increment(TI)was the highest in counter-beam lighting.The value of small target visibility was the highest in pro-beam lighting.
