City Lights which Facilitate Evacuation to Higher Ground : The Improvement Design Started from Social Lighting Experiments(<Special Issue>City Lights Supporting Security, Safety and Pleasant)

Abstract

The importance of evacuation to higher ground away from a tsunami safely at night has been recognized right after the Great East Japan Earthquake in 2011. One of principal methods of the evacuation lighting to higher ground is visualizing geographical features and the characteristics of evacuation areas by lights. The reasonable and energy efficient lighting could be realized by designing according to the required performances for each location. The improvement of evacuation lighting would lead regional development in disaster areas. It does not require a long period of time and a big budget as compared with other infrastructure constructions. This paper has reported the achievement of lighting social experiments in which evacuation lighting equipment was placed to disaster areas.
