摘要:Worldwide, many different actions have been taken by local and national governments to control the spread of COVID-19. The impact of these measures can be seen in different areas, especially in passenger transport and travel behaviour. This study examines the changes that have occurred in travel behaviour, using the example of the capital city of Warsaw, Poland, in relation to measures undertaken to control the spread of COVID-19 and the sense of safety among passengers that was supposed to be provided by public transport organisers. Data were collected through an online survey questionnaire that included questions about past (before COVID-19) and present (during COVID-19) travel behaviour, mode choice and the frequency of trips by public transport users in Warsaw. The results showed significant changes in mobility and travel behaviour along with most common threats seen by public transport users. There was a major shift from public to individual modes of transport in the city area. The outcomes of this study could play a significant role in transport planning in the case of any other situation that affects public transport on such a level as the COVID-19 pandemic has. In particular, local and national authorities could use this knowledge for better planning for any type of lockdowns.
