Article
The actual functions of a region may not reflect the intent of the original zoning scheme from planners. To identify the actual urban functional regions, numerous methods have been proposed with computational advancement. Specifically, remote sensing by image recognition, geodemographic classification, social sensing with big data and geo-text mini...

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...

Rebuilding communities requires an actionable approach to explicitly translate the concept of resilience into postdisaster recovery planning. Through clustering analysis using project titles and project summary, 940 resilience projects are grouped into infrastructure prototypes, economic development prototypes, housing prototypes, and environmental...
Article
Full-text available
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...
Article

During a natural disaster, mining messages from social media platforms can facilitate local agencies, rescue teams, humanitarian aid organizations, etc., to track the situational awareness of the public. However, for different stakeholders, the concerns about people’s situational awareness in a natural disaster event are different. Therefore, I dev...
Article
Even though exposure to urban green spaces (UGS) has physical and mental health benefits during COVID-19, whether visiting UGS will exacerbate viral transmission and what types of counties would be more impacted remain to be answered. In this research, we adopted mobile phone data to measure the county-level UGS visitation across the United States....

The transportation system, particularly the surface transportation system, has been evolving, albeit slowly. But that evolution has been exacerbated recently toward a smarter, more sustainable, and more resilient system. Connected and automated technologies enable vehicles smarter; electrical vehicles, and shared mobility, particularly shared micro...

The combined effect of global warming and the heat island effect keeps the temperature of cities rising in the summer, seriously threatening the physical and mental health of urban residents. Taking the area within the Sixth Ring Road of Beijing as an example, based on Landsat remote sensing images, meteorological stations, and questionnaires, this...
Article
Problem, research strategy, and findings. Planners need to read plans to learn and adapt current practice. Planners may struggle to find time to read and study lengthy planning documents, especially in emerging areas such as climate change and urban resilience. Recently, natural language processing (NLP) has shown promise in processing big textual...

Urban resilience efficiency is an important indicator to explore the relationship between resource consumption and urban resilience, shedding new light on the study of urban sustainable development. Based on the panel data of 2008, 2012, and 2017, this paper makes a spatiotemporal assessment on the urban resilience efficiency of 126 cities in the Y...
Article

Postdisaster recovery inevitably involves the tension between speed and quality, which are the two sides of postdisaster recovery. On one hand, speed is the key to ensure local businesses alive and provide short-term and long-term housing for residents and victims. For instance, if it takes two decades for a community to build back, residents and v...
Article
Ride-hailing has redefined vehicle access and has the potential to reduce travel difficulties for transit-poor areas and people with poor access to private and public transportation resources. Due to the lack of data, current studies lack a holistic understanding of how transportation resources serve different social groups and places in the ride-h...

Covid-19 has been recognized as a terrifying global health threat since its detection, with far-reaching consequences that are unprecedented in the modern era. Since the outbreak of the pandemic, social media and legacy media have collectively delivered health information related to COVID-19 to the public as a catalyst to community perception of ri...
Article
This paper deals with household-level flood risk mitigation. We present an agent-based modeling framework to simulate the mechanism of natural hazard and human interactions, to allow evaluation of community flood risk, and to predict various adaptation outcomes. The framework considers each household as an autonomous, yet socially connected, agent....

The rapid spread of COVID-19 has damaged the economy in the United States. To understand the resilience capacities of local businesses, we visualized the spatiotemporal patterns of permanently closed Points of Interest (POIs) after the outbreak of the pandemic. The results show that the counties with more business closures are also the counties wit...

Previous studies mainly substantiate the influence of neighborhood design on older adults’ travel behavior. This study goes beyond and examines how smart growth affects older adults’ travel behavior over time in the central Puget Sound. Using regression models for the years 1999, 2006, and 2014, we find that smart growth factors have significant bu...
Article
Social distancing and particularly staying at home are effective public health responses to the COVID-19 pandemic. The sheer scale of behavior changes across a mass population scale is unprecedented and will undoubtedly cause disproportionate hardships for certain vulnerable groups of population and marginalized communities during different periods...
Article
Citizens with different demographic characters presented varying responses and behaviors in the same disasters. Their divergent responses can impact their actual damages during crises. Previous studies have employed social media for analyzing citizens’ crisis responses. However, these studies missed the demographic dimension. To resolve this limita...
Conference Paper
Social groups are characterized by their demographic characters such as race/ethnicity and gender. Different demographic groups were found to have experienced significantly varying impacts of the same disasters. For instance, ethnic minorities were impacted more severely than the white during Hurricane Katrina. These varying impacts can be reflecte...
Article
Extreme commuters, who spend 90 min or more on one-way commuting, has been a rapidly growing group. A few studies explain extreme commuting from the socioeconomic and land-use perspectives. However, little research takes spatial variations into account, nor does it make a comparison of different transportation modes. This paper applies Geographical...

Home prices and rent prices in the USA have been growing steadily over the past decade. However, the COVID-19 pandemic has decimated entire sectors of the American economy, which makes the homebuying decision more intricate. We mapped multiple metrics to indicate the best place to buy a house amid COVID-19. For many counties in the central area of...

The rapid urbanization in China has been associated with a growing hunger for energy consumption and steadily-increasing CO2 emissions. In this paper, an integrated system dynamics model composed of four sub-models is developed to simulate the urbanization and energy consumption in China from 1998 to 2050. Three scenarios are provided: accelerated...

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...
Article
In this paper, we proposed an improved transportation network efficiency (TNE) measurement method, which is called passenger- and speed-weighted efficiency (PSWE). The new method is used to measure both origin-destination-level (OD-level) transportation efficiency and citywide transportation efficiency by integrating with the excess commuting (EC)...
Article
Considering and measuring the similarity of human activities remains challenging. Existing studies of similarity measures based on traditional edit distance (ED), specifically on activity patterns, do not reflect the spatiotemporal characteristics in the measurement model. Additionally, interdependence between activities is ignored in existing mult...
