Comparing the Spatial Querying Capacity of Large Language Models: OpenAI’s ChatGPT and Google’s Gemini Pro
Since the launch of ChatGPT in 2022 and Gemini in 2023, there has been growing interest in the potential application of generative artificial intelligence (AI) in geography and GIScience. As the need for geospatially capable generative AI tools increases, an empirical investigation of generative AI tools’ performance in spatial querying is urgently needed. To fill this gap, we conducted experiments to assess ChatGPT and Gemini regarding their abi…
Spnaf: An R package for analyzing and mapping the hotspots of flow datasets
This paper introduces {spnaf} (spatial network autocorrelation for flows), an R package designed for the hotspot analysis of flow (e.g., human mobility, transportation, and animal movement) datasets based on Berglund and Karlström’s G index. We demonstrate the utility of the {spnaf} package through two example analyses by data forms: 1) bike-sharing trip patterns in Columbus, Ohio, USA, using polygon data, and 2) U.S. airports’ passenger travel p…
Understanding inequalities in geographic accessibility to emergency cyclone shelters in Bangladesh under climate change
This research aims to explore inequalities in geographic accessibility to emergency cyclone shelters in Bangladesh, a country in the Global South that is prone to natural disasters. We begin by quantifying the walking time to the nearest cyclone shelters as a basic measure of accessibility. Additionally, we compute a more practical measure of accessibility by considering crowding effects in shelters due to the interactions between supply (e.g., s…
Bridging the gap: A social equity analysis of intra-city transit access to inter-city rail in Canada
Place identity: A generative AI’s perspective
Do cities have a collective identity? The latest advancements in generative artificial intelligence (AI) models have enabled the creation of realistic representations learned from vast amounts of data. In this study, we test the potential of generative AI as the source of textual and visual information in capturing the place identity of cities assessed by filtered descriptions and images. We asked questions on the place identity of 64 global citi…

Evaluating accessibility benefits and ridership of bike-transit integration through a social equity lens
The cost of climate change: A generalized cost function approach for incorporating extreme weather exposure into public transit accessibility
Public transit offers urban populations physical accessibility to resources and opportunities. However, at the same time, transit trips often expose users to extreme environmental conditions, such as extreme heat and cold since transit journeys usually include out-of-vehicle trip segments including walking and waiting. Such exposure can be considered as environmental health costs because exposure to weather extremes can lead to adverse health out…
The proposal of a 15-minute city composite index through integrating GPS trajectory data-inferred urban function attraction based on the Bayesian framework
Factors associated with Covid-19 vaccination rates in countries with different income levels: A panel analysis
Vaccination rate and their associated factors differed across income levels. There is no universal strategy for boosting vaccination rates during a pandemic. Consequently, country specific approaches, including promotional programs to raise awareness and interest in vaccination, are essential for preparing for future pandemics
Evaluating the impacts of supply-demand dynamics and distance decay effects on public transit project assessment: A study of healthcare accessibility and inequalities
Measuring exposure and contribution of different types of activity travels to traffic congestion using GPS trajectory data
Echoes of Home: Mapping Vulnerable Places for Cantonese‐Speaking Immigrants Seeking Family Doctors in the Greater Toronto Area
Family doctors serve as the initial contact for individuals seeking regular medical service like routine physical exam, diagnosis, and treatment of illness. Nonetheless, immigrant population who do not speak the official language usually prefers receiving healthcare in their own mother tongues. Past studies have focused on exploring accessibility to family doctors speaking Mandarin Chinese, which is not mutually intelligible with another major Ch…
Examining the socio-spatial patterns of bus shelters with deep learning analysis of street-view images: A case study of 20 cities in the U.S
Exploring Spatial Mismatch between Primary Care and Older Populations in an Aging Country: A Case Study of South Korea
With the rapid growth of aging populations in South Korea, it is important to assess spatial accessibility to healthcare resources as older adults may need frequent visits to hospitals. Healthcare spatial accessibility is measured based on available resources (e.g., physicians, beds, services), demands (e.g., population), and travel costs (e.g., distance or time). In this study, we employed an Enhanced Two-Step Floating Catchment Area (E2SFCA) me…
Job Accessibility as a Lens for Understanding the Urban Structure of Colonial Cities: A Digital Humanities Study of the Colonial Seoul in the 1930s Using GIS
This study examined the urban structure of colonial Seoul in the 1930s, the capital city of Korea under the rule of the Japanese empire, by adopting quantitative geographical methods. We utilized a job accessibility index to operationalize the urban structure. We also used geographic information science (GIScience) analysis tools to digitize neighborhood-level sociodemographic and parcel-level business location information from historical materia…

The Role of Distance‐Dependent Versus Localized Amenities in Polarizing Urban Spatial Structure: A Spatio‐Temporal Analysis of Residential Location Value in Columbus, Ohio, 2000–2015
This study examines the relative effects of distance‐dependent versus localized amenities in changing urban spatial structure of residential location values within urban areas. We also investigate the spatio‐temporal patterns of neighborhood value , which is the sum of distance‐dependent and localized amenity effects, at a local community scale. We use a hedonic housing price model that controls for residential property characteristics to disting…

Initial analysis suggests differences exist in dental outcomes according to neighborhood-level sociodemographic variables, even when access to dental care is similar
Measuring the Differentiated Impact of New Low-Income Housing Tax Credit (LIHTC) Projects on Households’ Movements by Income Level within Urban Areas
Social mixing is one of the key objectives of the housing policy in OECD countries. The Low-Income Housing Tax Credit (LIHTC) program, the largest affordable housing construction program in the US since 1986, has recently set creating mixed-income communities as one of the standards. As a project-based program, LIHTC developments are likely to influence residential mobility; however, little is known about its empirical effects. This study investi…
