The COVID-19 pandemic has given rise to a major impact on traffic mobility. To implement preventive measures and manage transportation, understanding the transformation of private driving behavior during the pandemic is critical. A data-driven forecasting model is proposed to estimate daily charging demand in the absence of the COVID-19 pandemic by leveraging electric vehicle (EV) charging data from four cities in China. It serves as a benchmark for quantifying the impact of the COVID-19 pandemic on EV charging demand. A vector autoregressive (VAR) model is then used to investigate the dynamic relationship between the changes in charging demand and potential influencing factors. Potential influencing factors are selected from three aspects: public health data, public concern, and the level of industrial activity. The results show that the magnitude of the decline in EV charging demand varied by city during the pandemic. Furthermore, COVID-19 related factors such as daily hospitalizations and national confirmed cases are the primary causes of the decline in charging demand. The research framework of this paper can be generalized to analyze the changes in other driving behaviors during the pandemic. Finally, three policy implications are proposed to assist other countries in dealing with similar events and to stimulate the recovery of the transport system during the post-pandemic period.
新冠疫情对交通出行产生了重大影响。为了实施预防措施并管理交通运输,了解疫情期间私人驾驶行为的变化至关重要。通过利用中国四个城市的电动汽车充电数据,提出了一种数据驱动的预测模型,用于估计在没有新冠疫情情况下的每日充电需求。它作为量化新冠疫情对电动汽车充电需求影响的基准。然后使用向量自回归(VAR)模型来研究充电需求变化与潜在影响因素之间的动态关系。潜在影响因素从三个方面选取:公共卫生数据、公众关注度和工业活动水平。结果表明,疫情期间电动汽车充电需求下降的幅度因城市而异。此外,与新冠疫情相关的因素,如每日住院人数和全国确诊病例数,是充电需求下降的主要原因。本文的研究框架可推广用于分析疫情期间其他驾驶行为的变化。最后,提出了三项政策建议,以协助其他国家应对类似事件,并在疫情后时期刺激交通系统的恢复。
