    Research background: With the onset of the Covid-19 pandemic, there has been a complete collapse in demand in global markets due to restrictions on movement and market paralysis. Among the sectors most significantly affected is tourism, which is predominantly dependent on the movement of clients. The performance of the tourism industry fell to a minimum during the pandemic. Restaurants and accommodation facilities were closed almost overnight by government intervention. The restriction of free movement has also forced airlines to curb their activities. These companies can be considered as an important globalization element, enabling travel to distant destinations. Purpose of the article: The article deals with the effects of the pandemic on European Union airlines, as well as the tools adopted to restore air traffic. Based on the analysis, the development of transport flows in air transport before and during the pandemic was evaluated. Furthermore, tools and measures taken to stimulate air services were analyzed and models of possible impacts on the EU aviation industry and selected economic factors were predicted. Methods: Basic mathematical and statistical methods, correlation analysis, comparisons and predictions were used for the analysis. Findings & Value added: The situation brings problems associated with redundancies, i.e. rising unemployment, declining GDP, falling stock markets or airline bankruptcies as in the case of the British Flybe. Based on 2019 data, it can be estimated that in the period March-June 2020, the demand for EU27 passenger air transport decreased by approximately 100 million passengers.

    In this paper, a national-wide study is conducted to investigate the impacts of COVID-19 on the public transit ridership in the top twenty metropolitan areas in the U.S. At first, COVID-19 composite index was developed to qualitatively measure the level of public fear toward COVID-19 in different metropolitan areas. After that, to analyze the impact of COVID-19 and some socioeconomic factors on transit ridership reduction during the COVID-19 pandemic, a random-effects panel data model was developed and the traditional correlation analysis was also conducted. According to the results of both analyses, it was found that the areas with higher median household income, a higher percentage of the population with a Bachelor’s degree or higher, higher employment rate, and a higher percentage of the Asian population are more likely to have more reductions in public transit ridership during the COVID-19 pandemic. On the other side, the areas with a higher percentage of the population in poverty, and a higher percentage of the Hispanic population are more likely to experience smaller reductions in public transit ridership.

    During May and June 2015, an outbreak of the Middle East respiratory syndrome (MERS) occurred in Korea, which raised the fear of contagion throughout society and suppressed the use of public transportation systems. Exploring daily ridership data of the Seoul bus transportation system, along with the number of infected patients and search volume in web portals, we observe that ridership decreased abruptly while attention was heavily focused online. Then this temporal reduction recovered exponentially with a characteristic time of 3 weeks when newly confirmed cases began to decrease. We also find with the data of ranked keywords of web portals that areas with severely reduced ridership tended to cluster and spatiotemporal variations of such clusters were highly associated with general hospitals where MERS patients were treated. On the other hand, the spatial reduction in ridership relaxed algebraically with the distance from a general hospital while the outbreak was severe. We further probe the influence of the epidemic outbreak in the framework of linear response theory, which relates the responses to the epidemic outbreak (“perturbation”) with correlations in the absence of the perturbation. Indeed, the spatial correlation function of the ridership changes is observed to follow a power law, sharing the same exponent as the spatial relaxation of the response function. This new theoretical approach offers a useful tool for understanding responses of public transportation system to epidemic or accidental disasters.

    Smart Sustainable city is an emerging concept of a complex long-term vision to overcome the problems arising in the cities with the help of new technologies. Some of such problems in the transport sector include congestion, carbon emissions, and inadequate public transit service supply. One probable solution to these can be through optimum utilization of disruptive mobility, which has hit this sector like a storm. This chapter presents the scenario of App-Based Shared Mobility (ABSM) services in the city of Bengaluru and the consequent impact it is creating on the urban travel trends, travel behavior, and car ownership. These services generate city-level data, which can be utilized to judge various aspects of city-wide traffic to improve the overall mobility. Moreover, the change in consumer desire from ownership to the accessibility of goods and services has penetrated the transport sector in the form of Transport Network Companies (TNCs), which has great potential to impact the public transit ridership as well as private vehicle ownership which is further explored in the chapter.

    Starting from the relationship between urban planning and mobility management, TeMA has gradually expanded the view of the covered topics, always following a rigorous scientific in-depth analysis. This section of the Journal, Review Notes, is the expression of a continuous updating of emerging topics concerning relationships among urban planning, mobility and environment, through a collection of short scientific papers. The Review Notes are made of four parts. Each section examines a specific aspect of the broader information storage within the main interests of TeMA Journal. In particular, the Urban practices section aims at presenting recent advancements on relevant topics that underlie the challenges that the cities have to face. The present note provides an overview of the policies and initiatives undertaken in three North American cities in response to the Covid-19 outbreak: New York City (US), Mexico City (MX) and Montreal (CA). A cross-city analysis is used to derive a taxonomy of urban policy measures. The contribution discusses the effectiveness of each measures in providing answers to epidemic threats in urban areas while, at the same time, improving the sustainability and resilience of urban communities.

    The impacts of COVID-19 on travel demand, traffic congestion, and traffic safety are attracting heated attention. However, the influence of the pandemic on electric bike (e-bike) safety has not been investigated. This paper fills the research gap by analyzing how COVID-19 affects China’s e-bike safety based on a province-level dataset containing e-bike safety metrics, socioeconomic information, and COVID-19 cases from 2017 to 2020. Multi-output regression models are adopted to investigate the overall impact of COVID-19 on e-bike safety in China. Clustering-based regression models are used to examine the heterogeneous effects of COVID-19 and the other explanatory variables in different provinces/municipalities. This paper confirms the high relevance between COVID-19 and the e-bike safety condition in China. The number of COVID-19 cases has a significant negative effect on the number of e-bike fatalities/injuries at the country level. Moreover, two clusters of provinces/municipalities are identified: one (cluster 1) with lower and the other (cluster 2 that includes Hubei province) higher number of e-bike fatalities/injuries. In the clustering-based regressions, the absolute coefficients of the COVID-19 feature for cluster 2 are much larger than those for cluster 1, indicating that the pandemic could significantly reduce e-bike safety issues in provinces with more e-bike fatalities/injuries.

    This article analyzes some relevant questions as regards the impact of COVID-19-related social living conditions on spatial planning policies and practices. The proposed discussion aims at highlighting and discussing a number of outstanding topics of spatial planning which public administrative bodies, practitioners, entrepreneurs and organizations operating in the profit and non-profit sectors, and the local communities should carefully consider with reference to a new planning outset after the lockdown period. Innovative and creative approaches should be identified and implemented when dealing with collective public spaces, shopping malls, retail activities and related areas, urban and regional mobility-related infrastructure and services, food-supply changes and their implications in terms of development of local food-producing practices, spatial social control and privacy, mitigation of climate change-related negative impacts, and public awareness and commitment towards losers, especially urban losers. Each of these points presents important challenges for the future of spatial planning. Some of these challenges are synthetically described and discussed in this article.

    The COVID-19 pandemic has had a rapid and significant impact on mobility. One of the most important responses of countries worldwide to slow the spread of the pandemic has been to restrict the movement of people, which has had a considerable effect on transport systems. However, the reduction of transport is not identical for all modes of transport: public transport has seen the greatest decline by far. Understanding urban modal share developments during a pandemic situation can help cities better prepare for transport management in the future. Highlights • COVID-19 measures decreased mobility by half in Budapest, Hungary • Modal share of public transport decreased dramatically due to COVID-19 measures • Car usage increased to 65% from 43% in the modal share • Bicycle usage saw the greatest growth rate by more than doubling it's share in the modal share • Bike sharing became more popular due to rapid measure, other mobility sharing systems saw lower than average decrease

    Understanding the behavioral intentions of public transit passengers during the COVID-19 pandemic is important for transmission control interventions oriented towards public transport system travel behavior. This paper studies the relationship between passengers’ intentions to use public transport, a set of psychological variables, and the influence of transport management policies (POLs) under COVID-19. Specifically, this study presents a framework integrating the theory of planned behavior (TPB) and customer satisfaction (CS) theory and uses partial least squares structural equation modeling (PLS-SEM) applied to the survey responses of 983 residents of Tianjin, China. The empirical results support the validity of this integrated model of public transit use intentions by confirming several hypothesized relationships among the psychological variables studied. Moreover, POLs under COVID-19 are shown to enhance commuters’ intentions primarily via subjective norms (SNs), perceived behavioral control (PBC), perceived service quality (PSQ), and CS. These findings reveal the psychological mechanism through which passengers adjust their public transport travel intentions during the COVID-19 period. Based on the results, some feasible suggestions are proposed to help restore confidence in public transport after the pandemic.

    Traffic congestion has been a persistent problem in cities globally. Theoretically, commuting-related congestion can be relieved by promoting working from home (WFH). Amid the COVID-19 pandemic, WFH arrangement has been encouraged or enforced to reduce the spread of the coronavirus. Under these circumstances, it was reported that traffic congestion has been alleviated in many cities. However, changes in congestion patterns within a city have not been studied in-depth. In this study, we analysed the congestion index (CI) at peak hours, when commuting-related congestion is typically most serious, throughout different waves of the pandemic in Hong Kong. Results show that under WFH arrangement, peak-hour congestion has been alleviated. Within a day, morning peak congestion was more relieved. Spatially, significant drops in CI were found not only in the central business district and urban cores but also in some new town areas. This paper has significant implications for urban planners in creating more sustainable cities that duly consider the commuting needs of residents, and cautions against the optimism that WFH can relieve urban transport problems despite jobs-housing imbalance. While the WFH arrangement has potentials to ease commuting congestion, future e-working and transport measures need to take spatial and temporal dimensions into account.
