Jülich scientist Ann Katrin Boomers explains the test procedure of the large-scale experiment to its participants. Each green cap worn by the participants is printed with an individual code. This allows ceiling cameras to create individual movement profiles.
As we see it
With green caps and pink dot stickers: in the name of science, 1,500 volunteers dressed this way strolled, crammed and waited in the Mitsubishi Electric Hall in Düsseldorf for four days in the service of science. They were participating in the large-scale experiment as part of the CroMa project for which researchers from Jülich, Wuppertal and Bochum are investigating crowding effects on railway platforms. Cameras recorded the participants’ movements; sensors collected further data such as stress and heartbeat. The extensive experiment aims to develop new concepts for getting a large number of passengers to, on and off trains safely and efficiently. The Federal Ministry of Education and Research is funding the project.
