This document describes the current practice in the design of the lighting of road tunnels and underpasses for motorized and mixed traffic. This concerns arrangements, levels and other parameters including daylight, which are related only to traffic safety. Aspects concerning visual comfort are generally chosen in agreement with national rules. The information in this report concerns any tunnel or underpass where the decision to provide lighting has been taken by any authority working within national legislation or other constraints. The design is based on photometric considerations, and all values of luminance or illuminance are maintained values.
The main body of the report covers the common aspects of Tunnel Lighting, and the various methods currently used in Europe are detailed in the annexes. No single method is recommended.
