| Abstract |
Recently, additional pedestrian passages are installed on urban tunnels in Korea. The lighting environment of the pedestrian passages should be appropriate to pedestrians. In this study, illuminance and discomfort glare where measured for determining the actual impact that pedestrians will be influenced by the tunnel lighting condition. Illuminance and discomfort glare were measured in ‘S tunnel’ which is located in Dong-Jack, Seoul, at day and night. And field survey on illuminance and discomfort glare was conducted to identify subjective responses of pedestrians. From the results of measurements and the survey, it is known that the lighting environment of the pedestrian passage in the tunnel is slightly dark especially at day time. UGR values which were measured at night were also higher than that at day. The results and methods of this study will be useful data for the ‘Environmental Improvement of Pedestrian passage in Tunnel’ project which was begun by Seoul City at 1st December 2008. |
