Energy savings of some 250000 kwh (30%) are forecast for the first year of operation of the Arlberg Tunnel with the introduction of a computer controlled lighting system. The tunnel lighting system, designed by Zumtobel Aktiengesellschaft uses 10000 fluorescent tubes set end to end in a single continuous strip giving improved visual conditions compared with spaced roof lighting. A feature of the lighting system is a ballast transformer which enables the tunnel energy requirement to be reduced from 14 w to 10 w/m. The Arlberg lighting system can be adjusted automatically to suit prevailing traffic conditions. Photometric efficiency is enhanced by use of a parabolic reflector luminaire system which is advantageous when tunnel fogging, caused by diesel fumes, becomes intense. (TRRL)
