A foot traffic model for the fire evacuation control in a building

The paper presents a model of foot traffic which is designed for using in a system of evacuation out of a building in case of fire – RINTD-Evac. The model supports the calculation of velocities and direction of people flows at each point depending on a situation in the building. The model uses experimentally established dependence of the rate of people movement from the number of people in near surroundings. The direction of motion at each point of the building is determined by the condition of minimality of achieving a safe zone. A brief description of software implementation of the model is given. A comparison of simulation results describing evacuation of people from a building, based on the model RINTD-Evac and well-known models FDS+Evac and Pathfinder is performed.
