“…5 The system is designed for sensing human movements in a large, open space and keeps the trajectory record of such movements. In addition, this system is adapted to measure movements of triage doctors and mock patients, even in outdoor environments, which is not possible with other similar humantracking systems, such as those at railroad crossings, 6 edges of railway platforms (Figure 1; available online only), 7 and the Expo Nagoya held in 2005 in Aichi Prefecture, Japan. 8 As there are high societal demands for increasing the knowledge of evacuation and disaster prevention in Japan, particularly after the event in 2011, this scientific research method of an emergency drill session, and the measured human trajectories during the session around the triage post, should be introduced.…”
