The restrictive measures implemented in response to the COVID-19 pandemic have triggered sudden massive changes to travel behaviors of people all around the world. This study examines the individual mobility patterns for all transport modes (walk, bicycle, motorcycle, car driven alone, car driven in company, bus, subway, tram, train, airplane) before and during the restrictions adopted in ten countries on six continents: Australia, Brazil, China, Ghana, India, Iran, Italy, Norway, South Africa and the United States. This cross-country study also aims at understanding the predictors of protective behaviors related to the transport sector and COVID-19. Findings hinge upon an online survey conducted in May 2020 (N = 9,394). The empirical results quantify tremendous disruptions for both commuting and non-commuting travels, highlighting substantial reductions in the frequency of all types of trips and use of all modes. In terms of potential virus spread, airplanes and buses are perceived to be the riskiest transport modes, while avoidance of public transport is consistently found across the countries. According to the Protection Motivation Theory, the study sheds new light on the fact that two indicators, namely income inequality, expressed as Gini index, and the reported number of deaths due to COVID-19 per 100,000 inhabitants, aggravate respondents’ perceptions. This research indicates that socio-economic inequality and morbidity are not only related to actual health risks, as well documented in the relevant literature, but also to the perceived risks. These findings document the global impact of the COVID-19 crisis as well as provide guidance for transportation practitioners in developing future strategies.

COVID-19 pandemic has heavily impacted the global community. To curb the viral transmission, travel restrictions have been enforced across the world. The dataset documents the mobility disruptions and the modal shifts that have occurred as a consequence of the restrictive measures implemented in ten countries: Australia, Brazil, China, Ghana, India, Iran, Italy, Norway, South Africa and the United States. An online questionnaire was distributed during the period from the 11st to the 31st of May 2020, with a total of 9 394 respondents. The first part of the survey has characterized the frequency of use of all transport modes before and during the enforcement of the restrictions, while the second part of the survey has dealt with perceived risks of contracting COVID-19 from different transport modes and perceived effectiveness of travel mitigation measures. Overall, the dataset (stored in a repository publicly available) can be conveniently used to quantify and understand the modal shifts and people's cognitive behavior towards travel due to COVID-19. The collected responses can be further analysed by considering other demographic and socioeconomic covariates.

As largely documented in the literature, the stark restrictions enforced worldwide in 2020 to curb the COVID-19 pandemic also curtailed the production of air pollutants to some extent. This study investigates the perception of the air pollution as assessed by individuals located in ten countries: Australia, Brazil, China, Ghana, India, Iran, Italy, Norway, South Africa and the USA. The perceptions towards air quality were evaluated by employing an online survey administered in May 2020. Participants (N = 9394) in the ten countries expressed their opinions according to a Likert-scale response. A reduction in pollutant concentration was clearly perceived, albeit to a different extent, by all populations. The survey participants located in India and Italy perceived the largest drop in the air pollution concentration; conversely, the smallest variation was perceived among Chinese and Norwegian respondents. Among all the demographic indicators considered, only gender proved to be statistically significant.

The dataset deals with the air quality perceived by citizens before and during the enforcement of COVID-19 restrictions in ten countries around the world: Australia, Brazil, China, Ghana, India, Iran, Italy, Norway, South Africa and the United States. An online survey conveniently translated into Chinese, English, Italian, Norwegian, Persian, Portuguese collected information regarding the perceived quality of air pollution according to a Likert scale. The questionnaire was distributed between 11-05-2020 and 31-05-2020 and 9 394 respondents took part. Both the survey and the dataset (stored in a Microsoft Excel Worksheet) are available in a public repository. The collected data offer the people's subjective perspectives related to the objective improvement in air quality occurred during the COVID-19 restrictions. Furthermore, the dataset can be used for research studies involving the reduction in air pollution as experienced, to a different extent, by populations of all the ten countries.

The issues encompassing planning and management of the urban space are directly related to the transport system, of which the flow plays a central role. Therefore, an interdependence among urban tissue, space structuring, and demand for mobility are taken into account. The objective of this work, using the data taken from the last two Origin and Destination surveys (2002 and 2012), is to assess the possible reduced power of attraction of the Central Area of Belo Horizonte by means of the motorized flows as a result of the process of induction of power of attraction of new urban centralities through planning and management policies. The results presented in this work generally indicate that the spatial structure of Belo Horizonte has remained concentrated in the Central Area, though new flows seem to converge to the consolidation of new municipal centralities. Even if additional care in the interpretation of results is necessary due to the limited time cuts and the database used, besides the specific features of Belo Horizonte, the empirical evidence translated in the proposed indicators allow a more accurate reflection on the recent urban space configuration, with the connections established through the space mobility of the population.

En la ciudad de Belo Horizonte (Brasil), observamos un importante avance en el proceso de envejecimiento de la población. Este proceso plantea desafíos para la investigación sobre los impactos de estas transformaciones en la configuración de la vida urbana. Nuestra investigación busca establecer la relación entre el envejecimiento y las prácticas de movilidad en términos de motivos, modos y frecuencias, así como con las centralidades creadas sobre la base de la práctica de desplazamiento de la población mayor. Para ello, se desarrolló un Index of elderly Centrality (IeCf) utilizando los flujos del grupo estudiado como proxy de centralidad. En cuanto a los viajes, observamos una reducción en la frecuencia y relevancia de los desplazamientos en transporte público y a pie, especialmente entre las mujeres. Además, identificamos áreas de concentración de viajes más dispersas, en centralidades diferentes a las ya consolidadas en el municipio, las cuales configuran nuevas áreas centrales que atienden demandas más específicas relacionadas con la población mayor.
