Free webinar on “WUI-NITY: a platform for the simulation of wildland-urban interface fire evacuation”

Blog Post created by amandakimball Employee on Oct 8, 2019

Fires in wildland-urban interfaces (WUI) are associated with severe negative consequences, such as large community evacuation, property losses social disruption, short- and long-term damage to infrastructure, injuries, and evacuee and responder fatalities. Wildland fires represent an important safety issue in many regions of the world. The future expansion and increased complexity of wildland urban interfaces (WUI) pose severe challenges to community safety from an evacuation perspective.


WUI incidents require a multi-domain approach to assess their impact and the effectiveness of any mitigation efforts implemented. A simulation framework that can establish evacuation performance ahead of time (before responses are implemented), would complement current planning and educational approaches and broaden the scope of the evidence available in a cost-effective way. Such a framework might be used to predict how an evacuation develops based on current and possible future fire conditions, given different affected populations and evacuation decisions and the access/availability of different resources (e.g., road access, public transport, traffic congestion, etc.). To achieve this, the simulation framework would need to represent the core components driving the incident; e.g., a predictive model of residential response, fire development and traffic flow.


A specification for such an integrated platform architecture was developed during a 2017 FPRF research project. The WUI-NITY project aims at developing an integrated software platform for the simulation of wildland-urban interface (WUI) evacuation scenarios that can be used both before an incident for planning and during an incident to inform decisions. The primary application of this platform is the ability to generate dynamic vulnerability maps from coupled fire, pedestrian and traffic sub-models. The webinar will discuss the outcomes from this effort. The final project report will be available on the FPRF website.
