【摘要】 城市隧道单一的光环境条件会在不同程度上给驾驶员造成视觉疲劳,诱发行车事故,为隧道驾驶安全带来隐患。防撞侧石连续防眩引导光带是一种提升城市隧道照明安全的有效手段,可为隧道光环境营造更好的条件,保障驾驶安全。本文基于Dialux照明设计软件,结合杭州博奥隧道的特点,模拟计算不同工况下防撞侧石连续防眩引导光带照度值,该类指标可直接反映驾驶员对防撞侧石的亮度感知能力,从而分析出防撞侧石连续防眩引导光带参数对于光环境的照度不同影响,并结合隧道光环境样板段现场测试数据对防撞侧石连续防眩引导光带效果进行了验证。研究表明侧石连续防眩引导光带凸显隧道内环境边界感,并可适当辅助路面、壁面照明。因此灯具的选取建议以亮度增量指标为主,其次辅以路面和壁面亮度增量。文章就城市隧道照明安全及内环境提升关键技术难题开展研究,提出了防撞侧石连续防眩引导光带及其量化设计方法,从行车引导和侧壁空间识别角度有效提升了驾驶安全性。更多还原

【Abstract】 The single light environment condition in urban tunnel may cause visual fatigue to drivers to varying extents,induce traffic accidents and pose hidden dangers to driving safety in tunnels.The continuous anti-glare guiding light band along anti-collision curbs is an effective means to improve lighting safety in urban tunnels and can create better conditions for light environment in the tunnel to ensure driving safety.Based on Dialux lighting design software and in combination with the characteristics of Hangzhou Boao Tunnel,the illuminance values of continuous anti-glare guiding light band along anti-collision curbs were simulated and calculated under different cases in this paper.These indicators could directly reflect the driver’s brightness perception ability for anti-collision curbs,so as to analyze different effects of continuous anti-glare guiding light band parameters along anti-collision curbs on the illuminance of light environment.Moreover,the effect of continuous anti-glare guiding light band along anti-collision curbs was verified in combination with the field test data in sample section of light environment.The research results indicate that the continuous anti-glare guiding light band along curbs highlights environmental boundary feeling in the tunnel and could properly assist pavement and sidewall lighting.Therefore,it is suggested to select the lamps focusing on the brightness increment index,followed by the brightness increment on pavement and sidewall.In this paper,key technical problems of lighting safety and internal environment improvement in urban tunnels were studied to put forward the continuous anti-glare guiding light band along anti-collision curbs and relevant quantitative design method,which could effectively improve the driving safety from the perspectives of driving guidance and sidewall space recognition.更多还原
