This paper analyzes the relation between COVID-19, air pollution, and public transport mobility in the Mexico City Metropolitan Area (MCMA). We test if the restrictions to economic activity introduced to mitigate the spread of COVID-19 are associated with a structural change in air pollution levels and public transport mobility. Our results show that mobility in public transportation was significantly reduced following the government's recommendations. Nonetheless, we show that the reduction in mobility was not accompanied by a reduction in air pollution. Furthermore, Granger-causality tests show that the precedence relation between public transport mobility and air pollution disappeared as a product of the restrictions. Thus, our results suggest that air pollution in the MCMA seems primarily driven by industry and private car usage. In this regard, the government should redouble its efforts to develop policies to reduce industrial pollution and private car usage.

Until recently, addressing the environmental externalities associated with the use of the private car and single occupancy vehicles has been the focus of the airport ground access policies worldwide. However, with the emerging unprecedented challenges of the COVID-19 pandemic, which have already changed the way we live, work, and travel, encouraging a change in commuter behavior has become even more important. This has necessitated that existing strategies be reconsidered in favor of adapting to a highly uncertain “COVID-19 world.” Historically, there has been a dearth of literature relating to airport employees’ ground access even though as a group employees represent an important segment of airport users with complex access requirements. This paper therefore focuses on airport employee related airport ground access strategies considering an emerging understanding of the future impacts of COVID-19 on global air travel. Pre-COVID strategies are investigated by conducting a documentary analysis of the most recent ground access strategies of 27 UK airports. The findings reveal that airport ground access strategies were mainly focused on setting targets and producing policy measures in favor of reducing car use and increasing the use of more sustainable transport modes including public transport, car sharing, and active travel (walking, cycling). However, measures encouraging public transport and car sharing will be more difficult to implement because of social distancing and fear of proximity to others. Instead, initiatives encouraging remote working, active travel, and improved staff awareness will be at the forefront of the future ground access strategy development.

This chapter examines the experiences and responses of Arab Palestinians, Ethiopian Jews, and Mizrahi Jews in Israel to stigmatization and discrimination. It first explains the historical and socioeconomic context for the three groups, taking into account the legacy of Zionism that shapes their experiences, the status of Arab Palestinians in the Jewish polity, and questions of ethno-national identity, exclusion, and inclusion affecting Mizrahim and Ethiopians in Israel. It then provides an overview of the Tel Aviv–Jaffa metropolitan area, the research site, before discussing the role of national belonging, race, and ethnicity in the formation of groupness among the respondents, with emphasis on self-identification and group boundaries. It also analyzes the groups' experiences of stigmatization and discrimination, and especially assault on worth, before concluding with an assessment of their reactions to such incidents as well as their views about the best ways to deal with social exclusion.

Impetuous multiplication of mobility and road traffic proliferation lead to concerns for increasing the attractiveness of urban public transport. Compared to private car use, urban public transport attractiveness is conditioned, in particular, by travel times and certainty of respecting the transport schedules, meaning planned traffic stability. Traffic schedules are considered to be more stable as the primary delays from the announced schedule have low probabilities and values and their propagation as repeated delays is least noticed in time and space. Solutions for assuring traffic stability must take into consideration contradictory aspects, because introducing time reserves in the schedules means time travel extensions. In order to assure the stability of planned traffic, present paper develops studies of various models and methods that aim to reduce inherent primary delays. Thereby, for studying repeated delays on a complex network, a mathematical model adequate to a Discrete Event Dynamic System (DEDS), that in MAX-PLUS algebra becomes a linear system, was used. The paper concludes with a case study on an integrated network resulted from the superposition of Bucharest’s existing suburban rail network with the underground network designed for 2030, being identified measures for improving the stability indicators. Traffic stability is assessed on the basis of two indicators: instability coefficient and delay elimination rate. Main measure for improving stability indicators is the growth of time reserves taking into consideration the quality requirements resulting from the condition of maintaining a reduced planned travel time.

This article assesses airport ground access by public transport in China. Recent literature has highlighted the economic, environmental and social significance of airport ground access. Existing studies on airport ground access have predominately centred on North America and Europe and, to date, limited attempts have been made to assess the emerging Chinese market. Studies of urban and transport geography have detailed the shifting air connectivity of Chinese cities and the economic impacts, but have paid little attention to ground access to airports. We, therefore, assess the ground accessibility to major Chinese airports based on online map services. Specifically, we characterise airport ground access across entire cities, as well as comparing time and monetary costs for travelling between airports and city centres by private car and public transport. We conclude with suggestions for future research, and call for more systematic data collection related to airport ground access.
