Survey found that platform blue lighting can significantly reduce the risk of jump-track suicide

According to a recent survey in Japan, the installation of blue light lighting equipment at the rail transit platform will significantly reduce the occurrence of suicide by jumping tracks.

According to the report of the Japan’s “Yomiuri Shimbun” website on the 10th, the team of Tokyo Metropolitan University’s applied econometrics professor Sawada Kukura’s team came to the conclusion.

They analyzed the data of 71 stations in the Japanese capital from 2000 to 2010, during which a total of 128 suicide jumps occurred at these stations. In the 11 stations with blue lighting equipment, after the self-related equipment was installed at the booth, there was a suicide incident during the daytime.

Excluding the impact of factors such as the number of passengers, the number of suicidal cases that jumped at each station dropped by an average of 84% after the installation of blue lighting equipment. Investigators said that this phenomenon may be due to the calming blue color. Sawada Kang Koki said that installing blue lighting is as effective as preventing the railway from committing suicide by installing platform screen doors.
