SIMULATION AND DESIGN STUDY FOR INTERIOR ZONE LUMINANCE IN TUNNEL LIGHTING

An optimal solution for tunnel lighting designs was determined using a computer software. The road tunnel under construction 14481 m in length was selected in order to get an optimal design solution for tunnel lighting.The lighting, luminaries, and road parameters were changed and the resulting scenarios were examined in a simulation environment. The proposed approach can be applied for the illumination of interior zones in tunnels of 10 km or longer with significant reduction in energy consumption. The optimal luminance values that affect vision comfort in the tunnel were calculated in a simulation environment. As a result, the most economic lighting system and luminaries were chosen among solutions conforming to technical standards for luminance values.
