The objective of this study is to understand the spatial and temporal dynamics of suicides in commuting railway environments. Data on suicides in Stockholm commuting railway from 2006 to 2013 was analysed. The study sets out to identify significant clusters in suicides then evaluate whether commuting railway environments affect variations in suicide rates. Fieldwork inspection, spatial cluster techniques (NNHC and Getis-Ord statistics) and regression models underlie the methodology of study. Findings show no seasonality was observed in suicide cases, but winter months concentrate a larger share of events. Suicides do not occur evenly throughout the day but tend to take place more often in weekdays. Modelling findings shows that suicide rates increase with speed trains and decrease where barriers along tracks are installed. Although high speed trains are still a motive of concern for suicide prevention, findings call for a whole railway-approach to safety - one that extends maintenance beyond the platforms and stations' vicinities.
本研究的目的是了解通勤铁路环境中自杀行为的时空动态。分析了2006年至2013年斯德哥尔摩通勤铁路上的自杀数据。该研究旨在识别自杀行为中的显著聚集区，然后评估通勤铁路环境是否会影响自杀率的变化。实地考察、空间聚类技术（最近邻层次聚类法和Getis-Ord统计量）以及回归模型构成了该研究的方法基础。研究结果表明，自杀案例未呈现季节性，但冬季的自杀事件占比更大。自杀行为并非全天均匀发生，而是在工作日更为频繁。建模结果显示，自杀率随高速列车的出现而上升，在安装了轨道障碍物的地方则下降。尽管高速列车仍是预防自杀的一个令人担忧的因素，但研究结果呼吁采取全面的铁路安全方法——一种将维护工作扩展到站台和车站周边区域之外的方法。
