本文分析COVID-19对交通运输业的影响，以及对全球部分选定城市的行业节能和温室气体排放的后续影响。提出了一个智能交通模型，考虑四个指标，包括运输效率，技术集成，交通拥堵率，可达性比。虽然先前的健康危机（如SARS）影响了运输业，但COVID-19疫情是前所未有的，对该行业造成了特殊影响。与正常情况相比，加拿大民用航空活动下降了71%，而军用航空活动下降了27%。截至2020年6月底，流动性指数高于50%的城市包括布鲁塞尔、新加坡、斯德哥尔摩、里昂、巴黎、莫斯科，流动性指数最高的香港为76%。截至6月底，美国城市的流动指数最低，流动指数低于20%。公众对COVID-19的反应将超过SARS，这是可以预期和合理的假设。虽然英国人和加拿大人是在COVID-19完全控制之前保持经济和企业关闭的最大支持者，但中国人，俄罗斯人，印度人和意大利人认为无论如何都必须重启经济。结果显示，世界上大多数人都处于精神困扰状态，并将在COVID-19后面临紧张和焦虑问题。这种情绪在印度、日本、中国、英国、巴西和加拿大，介于68%和78%之间。卡车运输业是加拿大运输业温室气体排放的主要贡献者，占2019年总排放量的62%以上。鉴于COVID-19的影响，加拿大运输业于二零二零年的预测温室气体排放量估计为93兆吨二氧化碳当量。
This paper analyzes the impact of COVID-19 on the transportation sector and subsequent implications on the sectoral energy savings and greenhouse gas emissions in some selected cities worldwide. A model for smart transportation is proposed by considering four indicators, including transport efficiency, technology integration, traffic congestion rate, and accessibility ratio. While prior health crises, such as SARS, impacted the transportation sector, the COVID-19 pandemic is unprecedented, resulting in exceptional impacts on this sector. Canadian Civil Aviation activities dropped by 71%, compared to business as usual, whereas military aviation activities declined by 27%. As of the end of June 2020, cities with higher than 50% mobility index include Brussels, Singapore, Stockholm, Lyon, Paris, Moscow, and Hong Kong with the highest mobility index of 76%. American cities have the lowest mobility indexes as of the end of June with mobility indexes lower than 20%. It is expected and reasonable to assume that the public's response to COVID-19 will exceed that of SARS. While Britons and Canadians are the biggest supporters of keeping the economy and businesses shut until COVID-19 is fully contained, the Chinese, Russians, Indians, and Italians find it vital to restart the economy regardless. Results show that the majority of the world is in a state of mental distress and will face nervousness and anxiety issues post-COVID-19. This sentiment is strongest in India, Japan, China, the U.K., Brazil and Canada, ranging between 68% and 78%. The trucking industry is the main contributor to the greenhouse gas (GHG) emissions of the Canadian transportation sector, accounting for more than 62% of the total emissions in 2019. Given the impact of COVID-19, forecasted GHG emissions of the Canadian transportation sector for 2020is evaluated to be 93 megatonnes of carbon dioxide equivalents.
