摘要
隧道出入口区域亮度悬殊,历来是交通事故的多发区。在隧道接近段采取一定的减光措施,形成一个光过渡带,可优化行车环境,保证行车安全,本文通过对国内公路隧道入口的减光措施相关研究的分析,论述了减光措施的类型、优缺点及适用范围。针对国内减光措施的应用现状,简要论述了隧道洞口的减光措施在实际工程中应注意的应用要点。
Due to tremendous differences of brightness, the tunnel portal is always the place where high incidences of traffic accidents occur. If some light reduction measures were taken in the section close to the tunnel portals, it would form an optical transition zone which could optimize driving environment and ensure traffic safety. Through analyzing related researches of light reduction measures applied in highway tunnel portals, this paper introduces and summarizes the types, merits and demerits, and application scope of light reduction measures. In addition, combining with the domestic application status of light reduction measures utilized in highway tunnel portals, the paper briefly generalizes some considerable factors of light reduction measures in practice.
