Abstract

Cities have experienced different realities during the COVID-19 pandemic due to its impacts and public health measures undertaken to respond to and manage the pandemic. These measures revealed significant implications for municipal functions, particularly emergency services. The aim of this study is to examine the spatiotemporal distribution of emergency calls during different stages/periods of the pandemic in the City of Vaughan, Canada, using spatial density and the emerging hotspot analysis. The Vaughan Fire and Rescue Service (VFRS) provided the dataset of all emergency calls responded to within the City of Vaughan for the period of 1 January 2017 to 15 July 2021. The dataset was divided according to 11 periods during the pandemic, each period associated with certain levels of public health restrictions. A spatial analysis was carried out by converting the data into shapefiles using geographic coordinates of each call. Study findings show significant spatiotemporal changes in patterns of emergency calls during the pandemic, particularly during more stringent public health measures such as lockdowns and closures of nonessential businesses. The results could provide useful information for both resource management in emergency services as well as understanding the underlying causes of such patterns.

新冠肺炎大流行期间紧急呼叫的时空分析——以沃恩市为例
在2019冠状病毒病大流行期间,由于其影响以及为应对和管理大流行而采取的公共卫生措施,城市经历了不同的现实。这些措施对市政职能,特别是应急服务产生了重大影响。本研究的目的是利用空间密度和新兴热点分析,研究加拿大沃恩市在大流行不同阶段/时期紧急呼叫的时空分布。沃恩消防和救援局(VFRS)提供了2017年1月1日至2021年7月15日期间沃恩市响应的所有紧急呼叫的数据集。数据集按照大流行期间的11个时期进行划分,每个时期都与一定程度的公共卫生限制有关。利用每个呼叫的地理坐标将数据转换成形状文件进行空间分析。研究结果显示,在大流行期间,特别是在采取更严格的公共卫生措施(如封锁和关闭非必要企业)期间,紧急呼叫模式发生了显著的时空变化。研究结果可以为应急服务的资源管理以及理解这种模式的根本原因提供有用的信息。
