论文摘要
Covid-19正在显着影响每个社会部门，包括人类流动性和随后的道路交通安全。在这项研究中，我们分析了大流行对使用两个城市的交通事故的影响，即美国的洛杉矶和纽约市。具体来说，我们分析了与各个人口组相关的交通事故，交通事故在时间和空间中的分布以及涉及和不涉及其他运输模式（例如行人和驾车者）的交通事故的严重程度水平。我们已经进行了以下观察：1）大流行对某些年龄段，种族和性别的影响不成比例； 2）与大流行之前的时间段相比，交通事故的“热点”在时间和空间上都发生了变化，证明了不规则性； 3）非致命事故案件的数量减少了，但在大流行期间，严重和致命的交通事故案件的数量保持不变。
COVID-19 is affecting every social sector significantly, including human mobility and subsequently road traffic safety. In this study, we analyze the impact of the pandemic on traffic accidents using two cities, namely Los Angeles and New York City in the U.S., as examples. Specifically, we have analyzed traffic accidents associated with various demographic groups, how traffic accidents are distributed in time and space, and the severity level of traffic accidents that both involve and do not involve other transportation modes (e.g., pedestrians and motorists). We have made the following observations: 1) the pandemic has disproportionately affected certain age groups, races, and genders; 2) the "hotspots" of traffic accidents have been shifted in both time and space compared to time periods that are prior to the pandemic, demonstrating irregularity; and 3) the number of non-fatal accident cases has decreased but the number of severe and fatal cases of traffic accidents remains the same under the pandemic.
