While the discussion on this urban development paradigm has revolved around the intensive use of technologies, the academic literature increasingly calls for shifting the focus to the people living in the cities. This paper argues that to achieve a people-centred smart city, cities should include the perspectives of all the local stakeholders. Under this assumption, this paper provides the views of the local stakeholders in a medium-sized city in Tennessee, Chattanooga. Particularly, this study explores their perceived smart city concept, the ethical standards that should guide smart city projects, the desired future projects in their community, and the barriers to implementing them. The data was collected using a combination of participatory budgeting, five focus groups, and twenty-eight interviews with city dwellers, entrepreneurs, university faculty, non-profit members, and government officials. The results suggest that, far from the image of a highly technological city, the stakeholders envision a city dedicated to improving the quality of life and environmental sustainability. Furthermore, to achieve this smart city, the projects need to be based on full transparency and the promotion of social inclusion. In contrast to the dominant trend towards the privatization of urban space, this study finds that the stakeholders prefer public based smart city projects such as ICT-based public transport services. However, its successful implementation will have to overcome the barriers caused by funding constraints, public acceptance, and political interests. Cities may use the results of this study to design more responsible smart city projects that strike an optimal point between citizen engagement and technological applications and innovations while supporting all stakeholders’ needs.

This study concerns the relationship between urbanization and climate change vulnerability. Specifically, it investigates the spatial aspect of the relationship between climate change vulnerability and urbanization in Nigeria. The study is vital because the relationship between urbanization and climate change in Africa has remained unclear. An exploration and comprehension of country-specific relationships in Africa have remained scarce. In Nigeria, efforts to research climate change vulnerability (CCV) have not looked at its connection with urbanization. Via an integrated vulnerability assessment and based on secondary data, the paper examines the effect of urbanization on climate change vulnerability. It argues that urbanization does not significantly increase CCV in Nigeria. It shows that urbanization and CCV have a significant negative relationship in Nigeria, suggesting that more urban states have lower levels of CCV than relatively more rural states. However, it indicates that relatively more urban states in Nigeria tend to have lower sensitivity and higher adaptive capacity to climate change, but there is no clear rural-urban difference in exposure to climate change. It follows that while there is a rural-urban disparity in CCV, individual components of vulnerability may exhibit a different relationship with urbanization. Thus, it concludes that the impact of climate change is dynamic and complex. Hence, there is a need to open the urbanization-climate change nexus to a lively debate to further climate change scholarship. Thus, while taking an all-inclusive approach to addressing climate change is desirable, it is vital also to explore the impacts of individual elements that comprise vulnerability.","PeriodicalId":46464,"journal":{"name":"International Journal of Urban Sciences","volume":"26 1","pages":"582 - 603"},"PeriodicalIF":2.9,"publicationDate":"2021-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12265934.2021.1956365","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47208145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Not only the medical footprint of this pandemic was enormous, also its mental-health fallout will take us many more years to understand in full detail. Also the societal impacts and behavioural patterns of the post COVID-19 era are still hard to foresee. Several scholars believe that the fallout of the crisis is expected to fundamentally change business industries and customers’ needs. With this in mind, the International Journal of Urban Sciences has launched a special issue related to the behavioural change of activities and travel in response to the pandemic disease. Indeed, mobility patterns and transport are simply a derived demand, i.e. derived from activities we do, and if society is to change fundamentally, also mobility will follow this evolution without any doubt. We are proud to present to you in this special issue a selection of seven papers, which went through a rigorous blind review process, nicely illustrating the aforementioned societal and behavioural changes due to COVID-19. A summary of the different contributions is mentioned below. In a first paper, Abbas Ziafati Bafarasat conducted a meta-analysis of COVID-19 lessons to primarily characterize the application of anticontagion strategies that are situated in their contextual specifications. To guide prior preparations for future application of pandemic management strategies, this paper nicely consolidates lessons learned in implementation of situated strategies and proposes preparations at the national level for elimination, at the local/community level for suppression, and at the regional level for mitigation. After that, the paper by Muhammad Ahsanul Habib and Md Asif Hasan Anik examined the long-term impacts of COVID-19 using an integrated transport and land-use modelling system. Specific behavioural attributes of households associated with and without a COVID-19 scenario are modelled and simulated up to year 2030 within an integrated transport, land-use and energy model. Apart from the metrological and technical contributions, the results of this study will offer transport and land-use planners insights into how households’ long-term decision making may evolve in the future due to the COVID-19 crisis and help develop policies to continue focusing on the sustainability goals for communities. In a first study from the United States, Hakan Yilmazkuday investigated the welfare costs of staying at home due to COVID-19 across socio-economic and demographic groups using daily census block group level data from the U.S.A.

For that, it first develops two possible scenarios, which are, (i) without COVID-19 pandemic, (ii) with COVID-19 pandemic. Specific behavioural attributes of households associated with each scenario are modelled and simulated up to the year 2030 within an integrated transport, land-use and energy (iTLE) model. iTLE is an agent-based microsimulation model developed for Nova Scotia, Canada. Results show that, if COVID-19 persists, most people who do not own a car will continue restraining themselves from purchasing one up to the year 2027. Most households having heads aged between 30 and 75 years and a yearly income above $100,000 will purchase new vehicles in year 2022, making the vehicle purchase rate doubled in the province. In terms of vehicle type choice decision, the use of SUVs will increase by 25% and 27% by 2025 and 2030, respectively, compared to year 2020. The pandemic will cause a 0%–74% increase in vehicle ownership in suburban areas by 2030. Additionally, the ability to ‘work from home’ and online school facilities may influence people to live further away from downtown. The results of this study will offer transport and land-use planners insights into how households’ long-term decision making may evolve in the future due to the COVID-19 crisis and help develop policies to continue focusing on the sustainability goals for communities.","PeriodicalId":46464,"journal":{"name":"International Journal of Urban Sciences","volume":"25 1","pages":"323 - 346"},"PeriodicalIF":2.9,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12265934.2021.1951821","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43412813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite these orders, however, people still have to make trips for work or to acquire essential goods. To better understand how these necessary trips influenced changes in individual mobility due to the pandemic, this study focused on the relationship between trip frequency and distance to median incomes, as well as between trip frequency and distance to supermarket density. We made use of the University of Maryland COVID-19 Impact Analysis Platform as our primary source for GPS travel data to study mobility changes at the county-level across the U.S.A. Results showed that trip frequency and distance were significantly different before the outbreak of COVID-19 and during three peak periods of COVID-19 infection. Specifically, we found the reduction of both frequency and distance of trips is negatively correlated to both median income and supermarket density. Thus we conclude that individual choice in adherence to staying-at-home is less dependent on the lockdown measures and more influenced by financial capacity and access to necessary goods and services. These findings could help inform policy development and programmatic responses to help people reduce their mobility. For example, government authorities might consider monthly stimulus or other financial support programs that would allow people greater access to delivery services. In the future, urban planners and policymakers should address the root causes that lead to such economic disparities and food insecurities, in order to build resilience in the face of possible future pandemics.","PeriodicalId":46464,"journal":{"name":"International Journal of Urban Sciences","volume":"25 1","pages":"366 - 385"},"PeriodicalIF":2.9,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12265934.2021.1952890","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46216758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While current urban transit policies and plans aim at higher public transit ridership, the negative perception that transit is unsafe increases in line with the spread of Coronavirus Disease 2019 (COVID-19) because of its higher risk in cases in which so-called 3C conditions are met: crowded areas, close-contact settings, and closed places. Thus, this study empirically examines how the perception of urban spaces changed by COVID-19 and how it influenced the choice of travel modes, accordingly, in the Seoul Metropolitan Area, South Korea. A structural equation model presents that changes in individual cognition and positive perception of policy changes during COVID-19 changes their perception of multi-use facilities negatively compared to before the COVID-19 outbreak. The negative perception is found to result in changes in travel mode choices by decreasing public transit ridership. Analytical findings show that intrinsic utility (i.e. risk perception) is revealed as a major determinant to understand travel mode choice. Also, in relation to the limitations of the current metropolitan transit system, the findings provide policy implications in the aspect of preventive measures and promoting micro-mobility for post-COVID-19 transit. Highlights The behavioural change under the pandemic is caused by fear of infection. Risk perception on public transit is affected negatively due to COVID-19. The increased risk perception leads to a reduction in public transit use. Risk perception is a major determinant to understand travel mode choice. Promoting micro-mobility will enhance the city's resilience during a pandemic.","PeriodicalId":46464,"journal":{"name":"International Journal of Urban Sciences","volume":"902 ","pages":"437 - 454"},"PeriodicalIF":2.9,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/12265934.2021.1951823","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41310053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through a multi-state comparison, the statistical linkage between the frequency of crashes related to DD and the influential factors was examined using county-level data for the period 2013-2017 in six states in the U.S. The results show that the frequency (relative risk) of crashes caused by DD tends to be higher in certain built environments, such as areas with high population density, whereas it is relatively lower on freeways and areas of a high level of traffic intensity. In addition, the influence of contributing factors such as urbanicity and age cohorts on the relative risks of crashes appears to vary among different states as well as severity levels. Such a discrepancy may reflect differences in driving behaviours and levels of urbanization across states. These findings provide important policy implications for transportation planners and decision-makers to customize targeted policy considerations to improve transportation safety and public health in response to distracted driving.
