This paper discusses possible long-term effects of COVID-19 on activity-travel behaviour. Making use of theories and concepts from economics, psychology, sociology, and geography, this work argues that lasting effects can be expected, and specifically that peak demand among car and public transport users may be lower than if the pandemic would never have happened. The magnitude of such effects at the aggregate level in terms of the total travel time of all inhabitants of a country or state is likely limited. Such lasting effects imply that additional infrastructure extensions to reduce congestion on roads and crowding in public transport might have a lower benefit-cost ratio than would be the case without these impacts. The paper discusses avenues for future research, including work on the role of attitude changes, the formation of new habitual behaviour, new social norms and practices, well-being effects, and the role of Information and Communication Technologies (ICT).

本文讨论了 COVID-19 对活动-旅行行为可能产生的长期影响。这项工作利用经济学、心理学、社会学和地理学的理论和概念，认为可以预期会产生持久影响，特别是汽车和公共交通用户的高峰需求可能低于大流行永远不会发生的情况。就一个国家或州所有居民的总旅行时间而言，这种影响在总体水平上的程度可能是有限的。这种持久的影响意味着，与没有这些影响的情况相比，为减少道路拥堵和公共交通拥挤而进行的额外基础设施扩建可能具有较低的效益成本比。本文讨论了未来研究的途径，包括关于态度改变的作用的工作，
