摘要
公路隧道入口加强段调光的精细化程度对行车安全与节能有重要影响。分析公路隧道入口加强照明调光精细化程度对行车安全的影响,利用云南楚大高速公路九顶山特长隧道及西宁南绕城高速公路隧道群LED智能化精细调光照明系统记录的洞外亮度变化曲线,换算出理论调光曲线,并与实际调光曲线进行图形化对比研究,揭示出导致亮度频繁跳变和亮度低于标准要求的形成原因,并提出通过增加调光亮度等级和减小调光间隔时间对不良调光方式进行改善。
The degree of dimming at the entrance of the highway tunnel has played an important role on traffic safety and energy saving.This paper analyzed the effect of enhanced lighting tuning at the entrance of expressway tunnel to driving safety.Based on the curve of the brightness of the tunnel recorded by the nine intelligent mountain tunnel and the intelligent lighting system outside the tunnel recorded by LED intelligent lighting tuning illumination system at Jiudingshan extra long tunnel of Yun ＇nan Chuda Expressway and tunnel cluster group of Xining South Ring Expressway,to convert the theoretical dimming curve,which is graphically compared with the actual dimming curve,so to reveal the cause of frequent brightness jump or brightness lower than the standard,and proposed improving method by increasing the brightness level and reduce the dimming interval to meliorate the poor dimming mode.
