摘要:

摘要:  为实现安全舒适的隧道入口段光环境,从驾驶员视觉功能及需求出发,提出了基于驾驶安全视认的隧道入口段光环境评价方法.以色温5 700 K、显色指数70的隧道入口段光环境为研究对象,对小客车驾驶员进行不同运行速度的实车视认试验,得到驾驶员动态视认特性规律;采用驾驶员驾驶过程中对小目标物的视认距离作为入口段光环境安全视认评价指标,应用MATLAB数学统计软件建立了不同运行速度下视认距离与入口段亮度折减系数定量逻辑关系模型;最终得到不同设计速度下能够满足驾驶视认需求的亮度折减系数阈值,与现行规范值相比略高.研究方法和结论可为实际隧道入口段光环境设置、监控及运行管理提供技术参考.

Abstract:

Abstract: In order to achieve safe and comfortable threshold zone light environment of tunnels, from the point of the driver’s visual function and requirement, a threshold zone light environment evaluation method was proprosed based on the driving safety of visual cognition. Taking the color temperature of 5 700 K, and the color rendering index of 70 threshold zone light environment as the research object, car drivers were chosen for visual cognition testing with different running speed, to get the drivers’ dynamic visual characteristics. The visual cognition distance was selected as the evaluation index of tunnel threshold zone safety visual cognition. The Matlab mathematical statistics software was applied to establish the logistic regression model of visual cognition distance and luminance reduction coefficient. Different design speed luminance reduction coefficients which could meet the demand of driving visual cognition, and slightly higher than the current specification values were obtained. The research method and conclusions is this paper can provide technical reference for actual tunnel environment setting, monitoring and operation management.

Key words: tunnel threshold zone, light environment, driving visual demand
