Greenery may be effective in mitigating particulate matter (PM) pollution. However, most previous studies have explored the effects of greenery on air quality from a two-dimensional rather than a three-dimensional (3D) perspective. In this study, a geographically weighted regression (GWR) model was constructed to explore the effect of street greene...

Building color and harmoniousness have been regarded as critical issues in planning historic districts. Harmoniousness of building façade colors (HBFC) is an indicator to evaluate the quality of the built environment, which can be perceived but is difficult to measure quantitatively. In addition, alleviating the impact of shadows in street-view ima...

Concentrations of airborne particulate matter (PM) are influenced by land cover types. Water bodies in cities can influence the spatial distribution of air pollution by altering the microclimate. However, the influence of water bodies on PM2.5 concentrations is complex and requires further exploration, especially at the microscale. In this study, a...

The lockdown measures enacted to control the COVID-19 pandemic in Wuhan, China, resulted in a suspension of nearly all non-essential human activities on January 23, 2020. Nevertheless, the lockdown provided a natural experiment to understand the consistency of the relationship between the urban form and air pollution with different compositions of...

With the increasing demand for liveable cities, efforts to promote high degrees of street vitality have become prevalent in contemporary urban design. Nevertheless, exploring the relationship between intangible street vitality and built environment features remains a challenge. With the help of multi-sourced urban data, a systematic analysis of 14...

The COVID-19 pandemic has been argued to be the ‘great equaliser’, but, in fact, ethnically and racially segregated communities are bearing a disproportionate burden from the disease. Although more people have been infected and died from the disease among these minority communities, still fewer people in these communities are complying with the sug...

This study presents an analytical approach for measuring the degree of balance between urban and tourism development, which has been previously analyzed qualitatively and was difficult to measure. With the help of 1012 million cellular data records generated by 20 million users in two weeks, we tracked the behavior of residents, commuters, and tour...

Exposure to PM2.5 and CO has been proven to be closely related to physical health. Since 2012, they have been added to the pollutant list for national monitoring in Wuhan. However, the fine-scale variation in pollution, especially at the street level, is complex and requires further exploration. In this study, the influence of urban form on the str...

The United States is bearing the brunt of coronavirus disease 2019 (COVID-19). The spatially uneven viral spread and community inequality will jointly bring about worse consequences. The combined effects on U.S. communities remain unclear, however. Given spatially heterogeneous compliance with the stay-at-home orders and the varying timing of local...

Amid sweeping efforts to get Americans to stay at home to slow the spread of the coronavirus disease, we geovisualized how foot traffic has increased or declined in relation to six types of trips across the United States: homes, workplaces, retail and recreation establishments, parks, grocery stores and pharmacies, and transit stations. The geovisu...
