A COMPUTER-MODEL FOR THE EVACUATION OF LARGE BUILDING POPULATIONS

The computer model 'SIMULEX' is designed to simulate the escape movement of thousands of individual people through large, geometrically complex building spaces. The model is intended for use both as a research and design tool to analyse the evacuation of large populations through a wide range of building environments. The computer program assigns a variety of attributes to each individual in the building population. These attributes include a co-ordinate position, angle of orientation, and a walking speed for each person. Specific algorithms that facilitate the simulation of escape movement include distance mapping, wayfinding, overtaking, route deviation, and adjustments to individual speeds due to the proximity of crowd members. These algorithms contribute to a computer package that displays the building plan and the position and progress of individual building occupants as they walk towards, and through the exits.
