The verification of wildland-urban interface fire evacuation models

Area of Science:

• Environmental Science
• Computational Science
• Disaster Management

Background:

• Wildfire evacuation models are crucial for public safety but require rigorous verification.
• Multi-physics models integrate complex factors like wildfire spread and human behavior, increasing verification challenges.

Purpose of the Study:

• To introduce a comprehensive verification protocol for multi-physics wildfire evacuation models.
• To ensure accurate implementation of individual model components and their interactions.

Main Methods:

• Developed a protocol with 24 distinct verification tests.
• Tests cover wildfire spread, pedestrian movement, traffic evacuation, and trigger buffers.
• Organized tests based on core evacuation modeling components (Population, Movement, etc.).

Main Results:

• Successfully applied the protocol to the WUI-NITY platform and k-PERIL model.
• The protocol includes tests for individual sub-models and their interdependencies.
• A reporting template was created to standardize verification application.

Conclusions:

• The proposed verification protocol enhances the credibility of wildfire evacuation model results.
• This work aims to stimulate further research and development in wildfire evacuation modeling.
• Standardized verification is essential for reliable disaster response planning.
