The external luminance, the climatic conditions as limpid sky or haze, the road surface wet or dry, the traffic speed and the related safe driver stopping distance, strongly influence the quantity of artificial support light necessary at the entrance of the tunnel. The design of the support lighting system in the road tunnel takes into account the critical conditions for these parameters that determine very high demand of electric power. With the aims to improve the safety and comfort for the drivers, avoiding the excesses of luminance and mitigating the cost and the energetic impact, in the paper is proposed a smart control able to operate and tune automatically the luminous flux emitted by the lighting system according to the input signals of the external luminance, the climatic condition and the traffic intensity.
