在审查和确定了隧道和道路地下通道照明应考虑的各种因素后，本文件提出了关于白天和夜间照明的建议。它还描述了为使该照明适应外部照明的波动，或在照明装置的正常电源发生故障的情况下，需要考虑的措施。还应注意维护，以确保装置的持久质量。还需要注意的是，虽然本出版物是旨在改善道路安全的一般活动的一部分，但安全取决于大量因素，其中照明只是一个特定的组成部分。 在这种情况下，照明的作用是通过确保物体的足够可见性，使道路使用者能够执行其视觉任务。本出版物取代CIE 88-1990《公路隧道和地下通道照明指南》。报告用英文写成，并附有法文和德文的简短摘要。它由40页组成，包括10个图表和10个表格。

After having reviewed and defined the various factors to be taken into consideration with regard to the lighting of tunnels and road underpasses, the present document sets out recommendations concerning the daytime and night-time lighting. It also describes the measures to be taken into consideration in order to adapt this lighting to the fluctuations in the external lighting or in the case of failure of the normal electrical power supply of the lighting installations. Attention is also given to maintenance which has to be carried out in order to ensure the lasting quality of the installations.It is also important to note that while this publication is part of a general activity aimed at improving road safety, safety depends on a large number of factors among which lighting is only one particular constituent. The contribution of lighting in this context is to enable the road user to perform his visual tasks by ensuring a sufficient visibility of objects.This publication replaces CIE 88-1990 "Guide for the Lighting of Road Tunnels and Underpasses".The Report is written in English, with a short summary in French and German. It consists of 40 pages with 10 figures and 10 tables.
