Analyzing teen drivers’ exposure to crash risk: An activity space-based approach
Teen drivers’ exposure to crash risk depends on where and how much they drive. Of the few published studies examining driving patterns and crash exposure, none focused on teen drivers, the highest crash risk group of all ages. This study used activity space measures to analyze everyday driving activities, resultant crash exposure, and associated factors for teen drivers aged 16–17. Using driving-related GPS-trajectory data collected from 76 teens…
Accessibility derivative: Measuring the accessibility contribution of public transit routes
Accessibility is one of the most essential objectives of public transit systems as the transit service’s useability and service quality. The accessibility of transit systems as a whole is well understood; however, it is still unclear how each route contributes to the system-wide accessibility. Meanwhile, with a higher risk of disruptions and more uncertainties from climate change and other disruptions, there is an urgent need to systematically st…

Understanding the spatiotemporal evolution of opioid overdose events using a regionalized sequence alignment analysis
The proposed methodology provides a new framework for understanding the spatiotemporal evolution of opioid overdose events, enabling policymakers and health researchers to develop effective interventions and policies to address this growing public health crisis
Inclusive Accessibility: Integrating Heterogeneous User Mobility Perceptions into Space-Time Prisms
Travelers’ day-to-day mobility depends on their perceptions, experiences, and personal characteristics. Many accessibility measures overlook perceptual factors and mainly consider space–time limitations of mobility, overestimating travelers’ potential mobility. We introduce a novel inclusive accessibility concept that advances time-geographic accessibility measures in light of travel behavior theories. We conceptualize inclusive accessibility as …

How does street space influence crash frequency? An analysis using segmented street view imagery
Road crashes in metropolitan areas are challenging to prevent because they stem from the interactions of drivers and other system users in intricate built environments. Recent theories indicate that features of the built environment may induce unsafe driving by shaping users’ expectations and behaviors. The availability of street view imagery and methods of scene parsing create new possibilities for understanding how features of the built environ…

What Is Essential Travel? Socioeconomic Differences in Travel Demand in Columbus, Ohio, during the Covid-19 Lockdown
The COVID-19 pandemic has profoundly reshaped urban mobility. During the lockdown, workers teleworked if possible and left home only for essential activities. Our study investigates the spatial patterns of essential travel and their socioeconomic differences during the COVID-19 lockdown phase in comparison with the same period in 2019. Using data from Columbus, Ohio, we categorized travelers into high, moderate, and low socioeconomic status (SES)…

Who Counts? Gender, Gatekeeping, and Quantitative Human Geography
How academic disciplines are represented and reproduced is a charged issue. In geography in particular, the challenge is not only who counts, especially with regard to gender and other factors, but also how the boundaries of the discipline are drawn and which subfields are acknowledged. This article contributes to both aspects of the discussion by extending recent research on gender, internationalization, and academic gatekeeping to additional su…
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…
Measuring risk of missing transfers in public transit systems using high-resolution schedule and real-time bus location data
The emergence of urban Big Data creates new opportunities for a deeper understanding of transportation within cities, revealing patterns and dynamics that were previously hidden. Public transit agencies are collecting and publishing high-resolution schedule and real-time vehicle location data to help users schedule trips and navigate the system. We can use these data to generate new insights into public transit delays, a major source of user diss…
The impacts of Covid-19 pandemic on public transit demand in the United States
The COVID-19 pandemic and related restrictions led to major transit demand decline for many public transit systems in the United States. This paper is a systematic analysis of the dynamics and dimensions of this unprecedented decline. Using transit demand data derived from a widely used transit navigation app, we fit logistic functions to model the decline in daily demand and derive key parameters: base value , the apparent minimal level of deman…
Robust accessibility: Measuring accessibility based on travelers' heterogeneous strategies for managing travel time uncertainty
Accessibility planning in American metropolitan areas: Are we there yet
Transportation-planning researchers have long argued that the end goal of a transportation system is increasing accessibility, or opportunities for individuals to meet their daily needs, but that US practice tends to focus on increasing mobility, or opportunities to travel farther and faster. This study finds evidence that the gap between theory and practice may be closing when it comes to accessibility, but that significant barriers still exist …
Measuring the Geometric and Semantic Similarity of Space-Time Prisms Using Temporal Signatures
Well-established techniques exist for measuring the similarity of space–time paths. These measures support clustering and aggregation of space–time paths as well as moving objects database queries based on similar movement patterns or semantics. Little attention has been paid, however, to the analogous problem of measuring space–time prism (STP) similarity, despite comparable applications. This article presents and evaluates a method for measurin…
Geographic information science III: GIScience, fast and slow – Why faster geographic information is not always smarter
The growing maturity and deployment of low-cost georeferenced sensors, navigation systems, fast wireless communication, cyberinfrastructure and the Internet of Things (IoT) is accelerating the speed of geographic data flowing from the environment and our capabilities for reacting quickly to geographic information, often automatically and in real-time. This is leading to the rise of real-time GIS and smart cities technologies. While reacting quick…
Time Geography and Space–Time Prism
Time geography is a constraints‐oriented approach to understanding human activities. Time geography highlights the necessary (though not sufficient) spatial and temporal conditions required for human activities. It also provides an elegant framework for incorporating these conditions into individualistic and ecological analyses and models of human behavior. Two central concepts in time geography are the space–time path and prism. The path represe…
Analyzing walking route choice through built environments using random forests and discrete choice techniques
Walking is a form of active transportation with numerous benefits, including better health outcomes, lower environmental impacts and stronger communities. Understanding built environmental associations with walking behavior is a key step towards identifying design features that support walking. Human mobility data available through GPS receivers and cell phones, combined with high resolution walkability data, provide a rich source of georeference…

Measuring segregation using patterns of daily travel behavior: A social interaction based model of exposure
Recent advances in transportation geography demonstrate the ability to compute a metropolitan scale metric of social interaction opportunities based on the time-geographic concept of joint accessibility. The method we put forward in this article decomposes the social interaction potential (SIP) metric into interactions within and between social groups, such as people of different race, income level, and occupation. This provides a novel metric of…
Place-Based versus People-Based Geographic Information Science
Geographic information science and technologies are revolutionizing basic and applied science by allowing integrated holistic approaches to the analysis of geographic locations and their attributes. However, the increasing mobility and connectivity of many people in the world means that the relationships between people and place are becoming more subtle and complex, rendering a place-based perspective incomplete. This article discusses the need t…
The Social Interaction Potential of Metropolitan Regions: A Time-Geographic Measurement Approach Using Joint Accessibility
We put forward a method for measuring the social interaction potential of a metropolitan region based on the time-geographic concept of joint accessibility. The metric is sensitive to prevailing land use patterns and commuter flows in the metropolitan region, time budgets, and the spatial distribution of joint activity locations. It is calculated via a geocomputation routine in which a representative subset of after-work, space–time prisms are in…
User‐centred time geography for location‐based services
Location‐based services assist people in their decision‐making during the performance of tasks in space. They do not consider the user's individual preferences, time constraints and possible subtasks to be performed. In order to account for these important aspects, a user‐centred spatio‐temporal theory of location‐based services is required. We propose such a theory by combining classical time geography with an extended theory of affordances. It …
Representation and Spatial Analysis in Geographic Information Systems
A common—perhaps modal—representation of geography in spatial analysis and geographic information systems is native (unexamined) objects interacting based on simple distance and connectivity relationships within an empty Euclidean space. This is only one possibility among a large set of geographic representations that can support quantitative analysis. Through the vehicle of GIS, many researchers are adopting this representation without realizing…
A Field-Based Theory for Time Geography
Classic time geography is powerful but rigid, admitting only uniform travel velocities. Computational time geographic methods that resolve the uniform velocity assumption through transportation networks or isochrones only partially address this weakness and do not have a rigorous theoretical foundation. This article develops an analytical time geographic theory for the case where travel velocities vary continuously across space. Using the continu…

Geographic information science II: Mesogeography
The 20th century witnessed the rise of social physics: the application of models and techniques developed for physical processes to social phenomena. Social physics left an enduring legacy in human geography via its stepchildren, spatial analysis and GIS, shifting geography from microgeography (description-seeking) and towards macrogeography (law-seeking). Social physics is back in the 21st century, and its renaissance with a concurrent rise in c…

Properties and Estimation of a Production-Constrained Alonso Model
The Alonso spatial interaction framework encompasses a wide variety of movement phenomenon models; most notably, the 'family' of spatial interaction models. The production-constrained formulation of the Alonso framework incoporates a destination-related relative accessibility effect and therefore generalizes the traditional production-constrained interaction model. In this paper, the properties and estimation procedures for a production-constrain…

Oral History: A Tool for the Study of Mexican American History in the Lower Rio Grande Valley of Texas
Scholars of Chicano history have been negligent in using oral history as a research tool whereas colleagues in other disciplines (e.g., Manuel Gomio, Paul Taylor, Oscar Lewis, and Americo Paredes) have used the technique extensively. The growing list of oral history projects since the early 1970's argues well for the greater use of oral history collections in writing on Chicano folklore, immigration, farm labor, political movements, and border hi…
Modelling accessibility using space-time prism concepts within geographical information systems
The space-time Of time geographical framework is a powerful perspective from which to analyse human behaviour. One of the central concepts in this framework is the space-time prism, which models individual accessibility to an environment. In this paper, the derivation and manipulation of space-time prism concepts within a geographical information system (GIS) are discussed. The required system inputs and desired outputs are identified and a gener…

Probability-Based Models of Spatial Search
The author develops and explores probability-based decision strategies for the consumer spatial search problem. These strategies extend experimental and analytical work in psychology on repeated choice among alternatives with varying reinforcement rates. Normative models postulate that the searcher attempts to maximize the frequency with which the lowest acquisition cost will be achieved over a multiple-trip horizon. A behavioral model postulates…

The Politics of Religion in an Age of Revival: Studies in Nineteenth-Century Europe and Latin America
This brief volume is a welcome challenge to the traditional interpretation of Catholic Church politics in nineteenth-century Europe and Latin America. The traditional view has liberals espousing rationality, modernity and progress in opposition to the church and its conservative allies, opposing the creation of a modern state. The authors of this work see a Catholic revival that frequently embraced Liberal goals of democracy and scientific progre…

A Measurement Theory for Time Geography
Hägerstrand's time geography is a powerful conceptual framework for understanding constraints on human activity participation in space and time. However, rigorous, analytical definitions of basic time geography entities and relationships do not exist. This limits abilities to make statements about error and uncertainty in time geographic measurement and analysis. It also compromises comparison among different time geographic analyses and the deve…
