A framework of fire evolution simulation for expressway

It is important to quickly and accurately determine the evolution of the fire when a fire breaks out on expressway. Current fire simulation can calculate fine-grained fire evolution parameters. However, fire simulation is a systematic work, which should consider the dynamic impact of the environment and rescue measures on the fire, and the dynamic evolution of human exposure to fire. In this work, we integrate environmental models, fire-resistant models, and human damage models into a fire simulation framework, aiming to describe the evolutionary state of multiple elements in a fire. The resulting framework consists of three layers, a parameters initialization layer, a model loading or parameters calculation layer and a real-time output and visualization layer. The simulation results demonstrate the power of the framework to include the coupling evolution of fire and weather, the reverse evolution of fire, and the evolution of damage caused by human exposure to fire. The framework can simulate expressway fires under multi-element coupling and rescue measures, which helps rescuers make correct decisions in fire rescue.
