The Evolution and Future Trends of Tunnel Design: Enhancing User Experience and Safety

Abstract

With the rapid development of transportation infrastructure, ultra-long high-speed tunnels are increasingly used in complex terrain areas, but their closed environment poses new challenges to driving experience and safety. This study takes the ultra-long high-speed tunnel in Nujiang Prefecture, Yunnan Province as the object, and analyzes "the consideration of user experience in tunnel design and its development trend". Through literature review, case study and interviews, the evolution of tunnel visual landscape design and the key factors affecting user satisfaction are summarized. The results show that light environment adaptation, spatial perception, visual guidance and cultural element integration are the core factors affecting user experience. The research results provide a theoretical basis and practical guidance for the design of ultra-long tunnels.
