터널의 시각 순응을 위한 시설 디자인 연구

Korean roads have many tunnels, due to the unique topography of the country. The difference in brightness within the tunnel and outside the tunnel is so great that the driver may experience a visual shock, which impairs his/her driving abilities and lead to devastating accidents. So for the safety of the driver, visual adaptation facilities, using natural light, need to be installed at the entrance and exit of tunnels in order to eliminate sudden visual impacts on the driver. This research proposes the use of visual adaptation facilities at the entrance and exit of tunnels to enhance driver safety. Also the use of natural light will contribute to energy conservation and save maintenance costs, compared to using artificial lightings. Furthermore, the simple designs of conventional tunnels were dull and did not blend in with the natural surroundings. Improvements to the openings of tunnels will enhance the drivers’ visual intake. Thus, the objective of this research is to examine, derive, and analyze problems related to the visual aspect of tunnels and suggest the exterior design of visual adaptation facilities that enhances safety and takes into account the natural environment. for the construction of facilities that would enhance visual adaptation, three types of design were tested, and a final review of the simulation model that was adopted was performed
