Protective action triggers have been used in different types of applications in wildfire evacuation. However, little research has been conducted on developing a computational framework for modeling triggers in wildfire evacuation. Based on a review of relevant research on the use of triggers in wildfire evacuation, we propose a computational framework for modeling triggers. Our proposed computational framework covers the following aspects of trigger modeling: 1) data model and spatial representation; 2) algorithms; 3) model coupling; 4) data; and 5) applications. Lastly, we summarize the challenges and opportunities in trigger modeling based on existing research and recent technological developments. This line of research will help evacuation researchers and practitioners develop a better understanding of how to model triggers and use triggers to improve public safety in wildfire evacuation.
