“…This study shows that NO 2 column density changes were not associated with public transport closure. The emphasis on social distancing in COVID-19 may foster the return of an automobile-oriented society to bring back air pollution, such as NO 2 and PM 2.5 , which is detrimental to the health of the urban population ( Loo and Tsoi, 2018 ). It is thus important to revitalize a safe and healthy environment for public transport and other active transport modes.…”

The COVID-19 pandemic has severely affected various aspects of life, at different levels and in different countries on almost every continent. In response, many countries have closed their borders and imposed lockdown policies, possibly bringing benefits to people's health with significantly less emission from air pollutants. Currently, most studies or reports are based on local observations at the city or country level. There remains a lack of systematic understanding of the impacts of different lockdown policies on the air quality from a global perspective. This study investigates the impacts of COVID-19 pandemic towards global air quality through examining global nitrogen dioxide (NO 2 ) dynamics from satellite observations between 1 January and 30 April 2020. We used the Apriori algorithm, an unsupervised machine learning method, to investigate the association among confirmed cases of COVID-19, NO 2 column density, and the lockdown policies in 187 countries. The findings based on weekly data revealed that countries with new cases adopted various lockdown policies to stop or prevent the virus from spreading whereas those without tended to adopt a wait-and-see attitude without enforcing lockdown policies. Interestingly, decreasing NO 2 concentration due to lockdown was associated with international travel controls but not with public transport closure. Increasing NO 2 concentration was associated with the “business as usual” strategy as evident from North America and Europe during the early days of COVID-19 outbreak (late January to early February 2020), as well as in recent days (in late April) after many countries have started to resume economic activities. This study enriches our understanding of the heterogeneous patterns of global associations among the COVID-19 spreading, lockdown policies and their environmental impacts on NO 2 dynamics.

“…The "Five Transformations" concept [40] indicates a way to definitively achieve sustainable transport, through the enumeration of transformations needed to promote sustainability in transport: city, economy, vehicle technology, modal division (i.e., the percentage distribution of daily average displacements by type of transport), and lifestyle. The intention is to educate the new generation so that, in the future, everyone has a more sustainable lifestyle.…”

The objective of this paper is to understand the interactions and functioning of the transportation of people and goods in the urban environment, and to propose an evaluation model in terms of sustainability and integrated transportation. Firstly, an in-depth literature review allowed us to understand the interactions and functioning of transport of people and goods in the urban environment, verifying the main initiatives to promote sustainability. The model was developed through a multi-criteria decision analysis methodology consisting of the application of Analytic Hierarchy Process (AHP) in a system specially developed for remote evaluation of the hierarchical model. The index was then applied to São Paulo, where two distinct periods were considered, and the results provided an assessment of the evolution of the city regarding the sustainability and integration of the passenger and freight systems. The conclusions indicate improve in the sustainability of the urban transport and logistics in the city, highlighting the importance of incentives to the use of active modes of transport and the communication channel with population.

“…Dense and mixed use urban development can contribute to the goal of greenhouse gas emission reductions, especially if oriented towards public transport systems (Banister, 2011;Schwanen, Banister, & Anable, 2011). Thus, consideration of land use configurations and policies is indispensable in promoting sustainable transport (Loo & Tsoi, 2018). Increased vehicle efficiency will not solve the issue of transport-related emissions if separation of urban functions, suburbanization, and car dependence prevail (Chapman, 2007).…”

Undoubtedly, climate change and its mitigation have emerged as main topics in public discourse. While accessibility planning is recognized for supporting sustainable urban and transport development in general, the specific challenge of reducing transport-related greenhouse gas emissions has rarely been directly addressed. Traditionally, accessibility is operationalized in line with the user perception of the transport system. Travel-time-based measures are considered to be closely linked with travel behavior theory, whereas CO2 emissions are not necessarily a major determinant of travel decisions. Given the changed prioritization of objectives, additional emphasis should be placed on the environmental costs of travel rather than solely the user costs. Accessibility analysis could account for this shift in perspectives by using CO2 emissions instead of travel time in the underlying cost function. While losing predictive power in terms of travel behavior compared to other implementations of accessibility, carbon-based accessibility analysis enables a normative understanding of travel behavior as it ought to be. An application in the Munich region visualizes the differences between travel-time-based and carbon-based accessibility by location, transport mode, and specification of the accessibility measure. The emerging accessibility landscapes illustrate the ability of carbon-based accessibility analysis to provide new insights into land use and transport systems from a different perspective. Based on this exercise, several use cases in the context of low-carbon mobility planning are discussed and pathways to further develop and test the method in cooperation with decision-makers are outlined.
