本研究的目的是分析首尔老年人交通事故的时空特征是如何随着时间的推移而变化的。采用核密度估计和热点分析方法分析老年人交通事故的空间特征，采用时空立方体、新兴热点和时空核密度估计方法分析老年人交通事故的时空特征。此外，将老年人交通事故分为驾驶员为老年人的情况和老年人为交通事故受害者的情况，使用2013年首尔的交通事故数据进行分析。主要研究结果如下：（1）老年人交通事故的热点因其是驾驶员还是受害者而异。(2)每小时的分析表明，老年驾驶员的交通事故的热点是在特定区域的汉江以北的时间从上午到下午，而老年受害者的热点分布在一个广泛的区域，从白天到晚上。(3)月度分析显示，冬季和夏季的热点较弱，而春季和秋季在首尔的徒步旅行和登山地区较强。此外，老年受害者的热点比老年司机的热点更加零星。(4)对2013年整个期间的分析表明，在汉江北岸的特定地区，涉及老年人的交通事故正在增加。我们期望这项研究的结果，有助减少日后涉及长者的交通意外。
The purpose of this study is to analyze how the spatiotemporal characteristics of traffic accidents involving the elderly population in Seoul are changing by time period. We applied kernel density estimation and hotspot analyses to analyze the spatial characteristics of elderly people’s traffic accidents, and the space-time cube, emerging hotspot, and space-time kernel density estimation analyses to analyze the spatiotemporal characteristics. In addition, we analyzed elderly people’s traffic accidents by dividing cases into those in which the drivers were elderly people and those in which elderly people were victims of traffic accidents, and used the traffic accidents data in Seoul for 2013 for analysis. The main findings were as follows: (1) the hotspots for elderly people’s traffic accidents differed according to whether they were drivers or victims. (2) The hourly analysis showed that the hotspots for elderly drivers’ traffic accidents are in specific areas north of the Han River during the period from morning to afternoon, whereas the hotspots for elderly victims are distributed over a wide area from daytime to evening. (3) Monthly analysis showed that the hotspots are weak during winter and summer, whereas they are strong in the hiking and climbing areas in Seoul during spring and fall. Further, elderly victims’ hotspots are more sporadic than elderly drivers’ hotspots. (4) The analysis for the entire period of 2013 indicates that traffic accidents involving elderly people are increasing in specific areas on the north side of the Han River. We expect the results of this study to aid in reducing the number of traffic accidents involving elderly people in the future.
