—外部亮度、晴空或阴霾等气候条件、路面潮湿或干燥、交通速度和相关的驾驶员安全停车距离，强烈影响隧道入口处所需的人工辅助光量。公路隧道辅助照明系统的设计考虑了这些参数的关键条件，这些参数决定了非常高的电力需求。为了提高驾驶员的安全性和舒适性，避免亮度过高，减轻成本和能量影响，本文提出了一种智能控制装置，能够根据外部亮度、气候条件和交通强度的输入信号自动操作和调节照明系统发出的光通量。
—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.
