Characterizing and Predicting Wildfire Evacuation Behavior: A Dual-Stage ML Approach

arXiv:2603.02223v1 Announce Type: new Abstract: Wildfire evacuation behavior is highly variable and influenced by complex interactions among household resources, preparedness, and situational cues. Using a large-scale MTurk survey of residents in California, Colorado, and Oregon, this study integrates unsupervised and supervised machine learning methods to uncover latent behavioral typologies and predict key evacuation outcomes. Multiple Correspondence Analysis, K-Modes clustering, and Latent Class Analysis reveal consistent subgroups differentiated by vehicle access, disaster planning, technological resources, pet ownership, and residential stability. Complementary supervised models show that transportation mode can be predicted with high reliability from household characteristics, whereas evacuation timing remains difficult to classify due to its dependence on dynamic, real-time fire conditions.

arXiv:2603.02223v1 Announce Type: new Abstract: Wildfire evacuation behavior is highly variable and influenced by complex interactions among household resources, preparedness, and situational cues. Using a large-scale MTurk survey of residents in California, Colorado, and Oregon, this study integrates unsupervised and supervised machine learning methods to uncover latent behavioral typologies and predict key evacuation outcomes. Multiple Correspondence Analysis, K-Modes clustering, and Latent Class Analysis reveal consistent subgroups differentiated by vehicle access, disaster planning, technological resources, pet ownership, and residential stability. Complementary supervised models show that transportation mode can be predicted with high reliability from household characteristics, whereas evacuation timing remains difficult to classify due to its dependence on dynamic, real-time fire conditions. These findings advance data-driven understanding of wildfire evacuation behavior and demonstrate how machine learning can support targeted preparedness strategies, resource allocation, and equitable emergency planning.

Executive Summary

This study employs a dual-stage machine learning approach to characterize and predict wildfire evacuation behavior in California, Colorado, and Oregon. Using a large-scale MTurk survey, the researchers identify latent behavioral typologies and develop predictive models for key evacuation outcomes. The study reveals consistent subgroups differentiated by various household characteristics and demonstrates the feasibility of using machine learning to support targeted preparedness strategies and resource allocation. The findings have significant implications for emergency planning and resource allocation, particularly in the context of wildfires. However, the study's reliance on self-reported data and its limited geographic scope may impact the generalizability of the results. Further research is needed to validate the findings and explore the applicability of these methods to other disaster contexts.
