A-Evac: the evacuation simulator for stochastic environment

TL;DR

A-Evac is an open-source evacuation simulator that models human evacuation in fire environments, incorporating probabilistic planning, interactions, and smoke effects, providing risk assessments and evacuation animations.

Contribution

This paper introduces A-Evac, a novel open-source evacuation simulation tool integrating probabilistic evacuation modeling, automatic route planning, and fire smoke impact analysis.

Findings

Risk values based on FED and F-N curves

Evacuation animations demonstrating scenarios

Impact of smoke on evacuation efficiency

Abstract

We introduce an open-source software Aamks for fire risk assessment. This article focuses on a component of Aamks - an evacuation simulator named a-evac. A-evac models evacuation of humans in the fire environment produced by CFAST fire simulator. In the article we discuss the probabilistic evacuation approach, automatic planning of exit routes, the interactions amongst the moving evacuees and the impact of smoke on the humans. The results consist of risk values based on FED, F-N curves and evacuation animations.
