高速公路特长隧道内注意力维持光环境设计

Attention-maintaining Light Environment Design in Super-long Tunnels on Highways

本文根据在医学领域内光对人注意力影响的研究成果,在特长隧道顶部设计了维持驾驶员注意力的光环境,采用特定光谱及辅助图案,在洞顶形成相应注意力唤醒段,用来维持驾驶员的注意力,提高隧道内行车安全系数,降低隧道内交通事故的发生率。本成果在北京冬奥会重大交通保障项目——延崇高速公路特长隧道内应用并得以验证,为我国的交通基础设施建设和隧道照明系统的升级改造提供了良好的借鉴。

According to the research findings on the impact of light on human attention in the medical field,a light environment is designed on the top of the super-long tunnel to maintain the driver attention.A specific spectrum of light and auxiliary patterns are employed to create an attention awakening segment on the tunnel ceiling.This design aims to sustain driver attention,enhance the safety factor of driving in tunnels,and reduce the occurrence of traffic accidents inside the tunnels.This achievementhas been applied and verified in the special long tunnel of Yanchong Expressway,a critical transportation project for the Beijing Winter Olympics.It provides valuable reference for the construction of transportation infrastructure and the upgrading of tunnel lighting system in China.
