To devise effective railway suicide countermeasures, it is necessary to identify stations where suicide is likely to occur. We explored the characteristics of stations where railway suicides have occurred and locations within the stations. (Study 1) Using suicide data from between April 2014 and September 2019 provided by a major railway company in Japan, station-specific suicide was modeled as an outcome variable in a multivariate Poisson regression model. (Study 2) With railway company staff, we visited stations where suicide frequently occurs and conducted fieldwork. (Study 1) Our estimation using a Poisson regression model revealed that railway suicides were more frequent when stations were serviced by passing trains, had a large number of passengers, and were located near psychiatric hospitals. (Study 2) Of 50 suicides, 48.0% occurred in front of benches or waiting rooms, 26.0% occurred at the front end of the platform, 24.0% occurred at the entrance to the platform, and 22.0% occurred at a blind spot for the train driver. All data were provided by one railway company in Japan, limiting the generalizability of the results. Stations where suicide occurs frequently have distinct characteristics. Focusing on suicide hotspots may aid suicide prevention.
为制定有效的铁路自杀防范措施，有必要识别可能发生自杀事件的车站。我们探究了发生过铁路自杀事件的车站特征以及车站内的具体位置。（研究1）利用日本一家大型铁路公司提供的2014年4月至2019年9月期间的自杀数据，在多元泊松回归模型中将特定车站的自杀事件作为结果变量进行建模。（研究2）我们与铁路公司工作人员一同走访了自杀事件频发的车站并开展了实地调查。（研究1）我们使用泊松回归模型进行的估计显示，当车站有过往列车服务、客流量大且位于精神病院附近时，铁路自杀事件更为频繁。（研究2）在50起自杀事件中，48.0%发生在长椅或候车室前，26.0%发生在站台前端，24.0%发生在站台入口，22.0%发生在火车司机的视线盲区。所有数据均由日本一家铁路公司提供，这限制了结果的普遍性。自杀事件频发的车站具有明显特征。关注自杀热点地区可能有助于预防自杀。
