In order to achieve the goal of energy-saving and safety driving in tunnel, this paper proposes an energy-saving fuzzy control system for highway tunnel lighting. Firstly, a control system for highway tunnel lighting based on IoT technology is constructed. Then, by considering tunnel exterior environmental luminance, traffic volume and vehicle speed as inputs and tunnel interior luminance as output, a fuzzy control model is designed. Based on experts’ experience and “Guidelines for Design of Lighting of Highway Tunnels (China)” (JTG/T D70/2-...
