This paper presents a method for obtaining airfield capacity estimates, using historical data from the Federal Aviation Administration’s Aviation Systems Performance Metrics (ASPM) database. The process first involves merging individual flights and quarter-hour airport runway operations datasets...

A changing climate is placing significant strain on urban environments as communities are contending with intensifying and more frequent hazards. Communities are simultaneously facing ongoing and new societal challenges that centre around a need for critical services and resources. To help people...

Resilience hubs are facilities located within communities designed to improve residents' quality of life and increase the community's ability to respond to emergencies and disasters (Baja, 2016, 2018, 2019; Ciriaco & Wong, 2022). These hubs provide essential services and resources that are...
