COVID-19 (Coronavirus disease 2019) brought about a huge change in the behaviour and mobility of citizens in all parts of the world. This change was mainly a consequence of the strong measures of isolation and social distancing taken by the different governments in most countries through the world. The specific measures adopted in each country, in combination with the particular characteristics of the spread of the virus, generated differentiated, although similar, behavioural changes. This article presents the analysis of a survey carried out in Spain in March 2020, where citizens were asked about their mobility preferences before, during and after the lockdown due to the virus. In turn, questions were asked about the preferred modes of transport in each of the situations and the perception of safety on public transport in their current conditions. The mobility questions were differentiated between commuting to work or studies, shopping and leisure. The results show that public transport was the most affected transport mode, with a considerable increase in the use of the bicycle and walking trips. At the same time, changes were observed in the behaviour of shopping trips, including a considerable decrease on the use of large supermarkets. Citizens perceived great uncertainty in planning leisure trips, the consequence of which could be that a higher proportion of people not being able to carry out their planned trips.

COVID-19（2019 年冠状病毒病）给世界各地公民的行为和流动性带来了巨大变化。这种变化主要是世界上大多数国家不同政府采取强有力的隔离和社会疏远措施的结果。各国采取的具体措施，结合病毒传播的特点，产生了虽相似但有所差异的行为变化。本文介绍了 2020 年 3 月在西班牙进行的一项调查的分析，该调查询问了公民在因病毒而封锁之前、期间和之后的出行偏好。依次询问了每种情况下首选的交通方式以及当前条件下对公共交通安全的看法。出行问题分为上班或学习、购物和休闲。结果显示，公共交通是受影响最严重的交通方式，其中自行车和步行出行的使用量大幅增加。与此同时，购物行为也发生了变化，其中大型超市的使用量大幅减少。公民在计划休闲旅行时感受到很大的不确定性，其后果可能是更高比例的人无法进行计划的旅行。
