This CEN Technical Report gives guidance on the design of the lighting of road tunnels and underpasses for motorized and mixed traffic. This guidance concerns arrangements, levels and other parameters including daylight, which are related only to traffic safety. Aspects concerning visual com¬fort should be chosen in agreement with national practice. The guidance in this report may be applied to any tunnel or underpass where the decision to provide lighting has been taken by any authority working within national legislation or other constraints. The report is based on photome¬tric considera¬tions, and all values of lumi¬nance and illuminance are maintained values.
The main body of the report covers the common aspects of Tunnel Lighting, and the various methods currently in use in Europe are detailed in the annexes. No single method is recommended.
