Abstract

Recently, many local governments have implemented various traffic safety policies for the elderly. This paper aims to analyze the impact of regional characteristics on traffic safety by aging stage. The main results are as follows. First, as the aging stage goes up, it is analyzed that the severity of traffic accidents are increasing while the number of traffic accidents are decreasing. In addition, the factors affecting the number and severity of traffic accidents are judged to not overlap, and are assessed to change as the aging stage goes up. Second, ten generalized linear regression models which are all statistically significant are developed. Third, regional characteristic indicators are estimated to have a significant impact on traffic accidents. Finally, the differentiated traffic safety policies are required for each aging stage. Increase of crosswalk right-side walking rate and management of traffic volume in ‘aging society’, increase of turn signal usage rate and expansion of general hospital beds in ‘aged society’, and enforcements of stop line conform and other violations in ‘super-aged society’ are evaluated to be vital to the policies.

老龄化阶段区域特征对交通安全的影响

最近，许多地方政府为老年人实施了各种交通安全政策。本文旨在按老龄化阶段分析区域特征对交通安全的影响。主要结果如下:首先，随着老龄化阶段的增加，交通事故的严重程度在增加，而交通事故的数量在减少。此外，判断影响交通事故数量和严重程度的因素不重叠，并评估随着老龄化阶段的增加而变化。其次，建立了10个具有统计显著性的广义线性回归模型。第三，估计区域特征指标对交通事故有显著影响。最后，针对不同的老龄化阶段，制定不同的交通安全政策。在“老龄化社会”中增加人行横道右侧通行率和交通量管理，在“老龄化社会”中增加转向灯使用率和扩大综合医院床位，在“超老龄化社会”中执行停车线符合和其他违规行为是至关重要的政策。
