ABSTRACT

The present study examines the impact of lockdown measures taken to control the spread of COVID-19 on road fatalities. The study is based on the data collected over the duration of six months for fifteen countries based on severity of COVID-19. Lockdown stringency and six daily mobility measures were selected to study the change in road mobility patterns due to lockdown measures. The fifteen countries were categorized into two clusters (C1 and C2) and generalized linear mixed model was considered for analysis. The model results revealed that stringent lockdown measures and high residential mobility reduced Crash Fatality Ratio (CFR) by 0.36% and 1.84%, respectively in cluster C2. Further, in cluster C1, travel restrictions on workplace and recreational activities decreased CFR up to 0.31% and 0.26%, respectively. Thus, overall model results specified that stringent law enforcement and appropriate compliance from the road users can effectively lessen traffic-related fatalities in unprecedented times.

摘要

本研究调查了为控制 COVID-19 传播而采取的封锁措施对道路死亡人数的影响。该研究基于根据 COVID-19 的严重程度在 6 个月内收集的 15 个国家/地区的数据。选择了封锁严格性和六项日常流动措施来研究由于封锁措施导致的道路流动模式的变化。这十五个国家被分为两个集群（C1 和 C2），并考虑使用广义线性混合模型进行分析。模型结果显示，在集群 C2 中，严格的锁定措施和较高的住宅流动性使撞车死亡率 (CFR) 分别降低了 0.36% 和 1.84%。此外，在集群 C1 中，对工作场所和娱乐活动的旅行限制分别将 CFR 降低至 0.31% 和 0.26%。因此，
