“…The second group of reviewed studies considers the analysis of variables determining air quality improvement during COVID-19 confinement, which is particularly relevant for a better understanding of how those variables can be crucial for air quality improvement within the context of urban regions [8,11,17,26,52,58,59]. A third group of studies focuses on analyzing air quality improvement stimulated by different transport policies at urban regions learning from the COVID-19 scenarios developed to restrict mobility, with particular interest in reducing car traffic [13,14,27,[60][61][62]. As observed in this study, there is a need to explore the effects of COVID-19 pandemic on transport use and modal shift since, several empirical analysis has been previously conducted (Table 6).…”

“…From the beginning of the quarantine in the State of São Paulo, there was a decrease in the movement of people and vehicles on the streets, caused by the closing of several public establishments such as parks, shopping malls, bars, restaurants and by the implementation of remote work in several companies [11]. Improvements on air quality were observed in several urban centers around the world caused by the closing of non-essential activities [12][13][14]. This situation offered an unprecedent opportunity to analyze the relationship between the social isolation, measures applied to contain the transmission of the new Coronavirus, and the air quality of the Metropolitan Region of São Paulo (MRSP).…”

Effects of the COVID-19 Pandemic on the Air Quality of the Metropolitan Region of São Paulo: Analysis Based on Satellite Data, Monitoring Stations and Records of Annual Average Daily Traffic Volumes on the Main Access Roads to the City

This paper presents an analysis of the effects of the COVID-19 pandemic on the air quality of the Metropolitan Region of São Paulo (MRSP). The effects of social distancing are still recent in the society; however, it was possible to observe patterns of environmental changes in places that had adhered transportation measures to combat the spread of the coronavirus. Thus, from the analysis of the traffic volumes made on some of the main access highways to the MRSP, as well as the monitoring of the levels of fine particulate matter (PM2.5), carbon monoxide (CO) and nitrogen dioxide (NO2), directly linked to atmospheric emissions from motor vehicles–which make up about 95% of air polluting agents in the region in different locations–we showed relationships between the improvement in air quality and the decrease in vehicles that access the MRSP. To improve the data analysis, therefore, the isolation index parameter was evaluated to provide daily information on the percentage of citizens in each municipality of the state that was effectively practicing social distancing. The intersection of these groups of data determined that the COVID-19 pandemic reduced the volume of vehicles on the highways by up to 50% of what it was in 2019, with the subsequent recovery of the traffic volume, even surpassing the values from the baseline year. Thus, the isolation index showed a decline of up to 20% between its implementation in March 2020 and December 2020. These data and the way they varied during 2020 allowed to observe an improvement of up to 50% in analyzed periods of the pollutants PM2.5, CO and NO2 in the MRSP. The main contribution of this study, alongside the synergistic use of data from different sources, was to perform traffic flow analysis separately for light and heavy duty vehicles (LDVs and HDVs). The relationships between traffic volume patterns and COVID-19 pollution were analyzed based on time series.

“…People's lifestyles during the COVID-19 pandemic have been largely affected by policy measures and individuals' risk perceptions, due to adjustments in daily life needs and resulting activity-travel schedules and behaviors Ding and Zhang, 2021). Many studies have been conducted with respect to remote-work, online study, travel frequency, family life, time use, energy consumption, social networking, and physical activities (Parady et al, 2020;Shamshiripour et al, 2020;Guzman et al, 2021;Pérez-Rodrigo et al, 2021;Zhang et al, 2021).…”

“What should be computed” for supporting post-pandemic recovery policymaking? A life-oriented perspective

The COVID-19 pandemic has caused various impacts on people’s lives, while changes in people’s lives have shown mixed effects on mitigating the spread of the SARS-CoV-2 virus. Understanding how to capture such two-way interactions is crucial, not only to control the pandemic but also to support post-pandemic urban recovery policies. As suggested by the life-oriented approach, the above interactions exist with respect to a variety of life domains, which form a complex behavior system. Through a review of the literature, this paper first points out inconsistent evidence about behavioral factors affecting the spread of COVID-19, and then argues that existing studies on the impacts of COVID-19 on people’s lives have ignored behavioral co-changes in multiple life domains. Furthermore, selected uncertain trends of people’s lives for the post-pandemic recovery are described. Finally, this paper concludes with a summary about “what should be computed?” in Computational Urban Science with respect to how to catch up with delays in the SDGs caused by the COVID-19 pandemic, how to address digital divides and dilemmas of e-society, how to capture behavioral co-changes during the post-pandemic recovery process, and how to better manage post-pandemic recovery policymaking processes.

“…For this purpose, a novel method of accessibility analysis is put forward that is based on this new approach of the proximity of urban social functions, more specifically, those covered by activities and services. Furthermore, although in recent years there has been a boom in theoretical reflections revolving around the concept of FMC and hyperproximity [5,[9][10][11], there is a lack of studies aimed at applying a systematic criterion to the practical analysis of the FMC [6,[12][13][14].…”

Barcelona under the 15-Minute City Lens: Mapping the Accessibility and Proximity Potential Based on Pedestrian Travel Times

Many academics, urban planners and policymakers subscribe to the benefits of implementing the concept of the 15-Minute City (FMC) in metropolises across the globe. Despite the interest raised by the concept, and other variants of chrono-urbanism, to date, only a few studies have evaluated cities from the FMC perspective. Most studies on the subject also lack a proper well-defined methodology that can properly assess FMC conditions. In this context, this study contributes to the development of an appropriate FMC-measuring method by using network analysis for services and activities in the City of Barcelona (Catalonia, northeastern Spain). By using network analyst and basing our analysis on cadastral parcels, this study is able to detail the overall accessibility conditions of the city and its urban social functions based on the FMC perspective. The resulting spatial synthetic index is enhanced with the creation of partial indexes measuring the impact of education, provisioning, entertainment, public and non-motorized transport, and care facilities. The results show that most residents of this dense and compact city live in areas with proximity to services, that can clearly be labeled as FMC, although there are some shortfalls in peripheral areas. Results validate the FMC methodology as a viable method to highlight spatial inequalities at the microscale level, a valuable tool for the development of effective planning policies.
