Smart growth by design
The classical transportation problem is an important urban and regional planning and policy-making analytic tool as it has the potential to provide deep insights into the competitive advantage of locations for different activities. While the classical transportation problem and its variants have been extensively employed in commuting efficiency studies, insufficient attention has been paid to its mathematical dual. This paper aims to revisit the …
Social Vulnerability, Locational Vulnerability, and Uncertainty in Wildfire Risk Index Construction
Over the past two decades, methods to measure and account for social vulnerability, or the ability of a community to prepare for, cope with, and recover from a natural disaster, have rapidly proliferated. Recognizing the multifaceted nature of vulnerability, researchers and practitioners now seek to combine social with locational (physical) vulnerability into singular indexes designed to identify areas of high risk. Central to such efforts are co…
Exploring the effects of wildfire events on movement patterns
Social vulnerability gaps
Demographic and socio-economic omissions in social vulnerability assessments are not uncommon. However, conclusions from incomplete population characterization contribute to inequity and marginalization of at-risk segments of society, individuals who require care, resource assistance, and tailored public policy. The unsheltered homeless are considered here as an underrepresented segment of socially vulnerable people in hazard assessment. The unsh…
Locational Decision-Making and Representational Impacts
The field of location analytics has long recognized coverage and accessibility as critical problem characteristics, as reflected in the work of Weber and von Thünen, among others. Attempts to address various associated complications, assumptions, and issues abound, including uncertainty, spatial representation, discrete approximation, and heuristic and exact solution, just to name a few. This article investigates unidentified continuous demand, e…
Geographical Compactness in Shape Assessment
Geographic shape has long been an intriguing feature of observed and defined facets of an area or region. Compactness reflects a critical element of shape with important practical and policy implications. It may suggest characteristics of urban/regional form, efficiency in trade and service provision, fairness in political representation and distributional qualities of the physical environment, among others. While there has been much study of com…
Critical neighborhood evacuation area identification
Locating and orienting facilities with anisotropic coverage
Siting facilities strategically is critical to ensure system design efficiency, enhance social equity and reduce operational costs. Coverage models look to optimize facility configuration, often to minimize the number of necessary facilities or maximize demand served within established proximity standards. Existing location models, such as maximal covering, often assume facility standards to be isotropic, resulting in a perceived circular service…
Geographic Fire Response Standards Emerging from Human–Environment Interactions
Natural and man-made disasters are generally characterized in terms of their human–environment interactions. Wildfire, or simply fire, is something that has naturally occurred over millions of years, but it is the interaction, disruption, and impact on humans that often generates much interest and concern. The growth of the built environment and human reliance on fire in everyday life can be a dangerous combination, putting people and property at…
A planning support framework to enable smart mobility
Planning support approaches can play a transformative role in shaping sustainable, resilient, and equitable urban landscapes that promote efficient mobility patterns. This paper develops a prescriptive framework that integrates Geographic Information Systems with a variant of the transportation problem to evaluate planning initiatives and inform land use policies and growth management strategies aimed at enhancing commuting efficiency at both loc…

Balancing Workloads through Co‐location in Covering Problems
Total demand suitably served and facility workload balance are two important considerations in location coverage. Previous work has dealt with workload balancing issues using a number of approaches, including imposing facility capacities and the use of multiple objectives focused on workload variation. However, a facility is usually restricted to a single service unit, inconsistent with strategies that allow for increased staffing such as multipl…
Mapping 3-D classroom seats based on partial object point cloud completion
3-D classroom seating information is of great significance in a host of planning contexts including indoor navigation and facility management. Mapping classroom 3-D seats based on a single-view LiDAR scan is challenging because of occlusions and viewpoint limitations. In essence, one is left with incomplete point clouds, making object recognition difficult. The aim of this paper is to acquire complete point clouds for objects in a room based on a…
A location analytics perspective of regional science at a crossroad
Location analytics have been a mainstay in regional science since its inception. Why? Perhaps the biggest reason is the ability to tease out important spatial heterogeneity nuances, but also to communicate geographically oriented analysis, planning, management and policy issues in rigorous ways, often as mathematical models, that can be subjected to further scrutiny and evaluation. Further, addressing broad challenges facing emergency response, f…

The Art of Geographical Analysis
Professor Arthur Getis was a prominent geographical analysis researcher and proponent. His research in geographical analysis was broad, with an eye on theoretical developments and application‐oriented details. However, there was so much more. His active participation and engaged discussion at symposia and conferences, in sessions, during breaks and less formally over drinks or a meal, stand out, even postretirement. His service and mentoring in m…

Locating a facility to simultaneously address access and coverage goals
This paper introduces a bi‐objective strategic location problem to address access and coverage. While previous research in continuous location modelling considered access coverage independently, none has approached such a problem in an integrated fashion. In this paper, a new mathematical formulation considering access and coverage is derived, and a solution algorithm to find the entire set of optimal tradeoff solutions is developed. Application …

Significance Assessment in the Application of Spatial Analytics
The breadth of spatial analytics relied on in geography is remarkable. These methods are used to gain insight, typically in the context of planning, management, decision making, and policymaking. The challenge is invariably establishing meaning in obtained findings, providing insights and knowledge. This is done, however, in very different ways depending on the spatial analytic approach, with statistical notions of significance a prevailing tool …
