Code of practice for the design of road lighting - Lighting of tunnels Ingestion-build-177197 Aspects not covered by thisRoad and traffic conditions in tunnels can differ considerably from those that prevail on the open road. The design of tunnel lighting installations should take these different conditions into account, particularly with regard to traffic safety. The object of installing lighting in a road tunnel is to enable traffic to flow through it with the same speed, degree of safety and comfort as on the approach roads.
