Due to overemphasis on landscape in highway tunnel landscape lighting construction,a series of problems in the aspects such as safety, economy and so on are caused. This paper first introduces the road tunnel landscape lighting and the research status at home and abroad. Through analyzing the current trend and main problems of landscape lighting, it is considered that the lack of scientific and reasonable design process is one of the main causeswhich induced problems in some projects. Then, referring to the thought and process system of urban landscape lighting design, the particularity of highway tunnel is integrated into the design process and analysis steps of urban landscape lighting, and the design system of highway tunnel landscape lighting is proposed. In the introduction of the design process, the common problems of highway tunnel landscape lighting are deconstructed and analyzed from different angles such as landscape lighting and traffic engineering, and the specific solutions and suggestions are put forward. Finally,it proposes the attitude of respecting the actual needs, treating the road tunnel landscape lighting rationally, and standardizing and guiding the benign development of the industry with scientific and reasonable planning and design system and process.
