Project description

Pedestrian simulations are employed for a wide variety of applications, namely the determination of maximum evacuation times, the identification of possible conflict points or bottlenecks in buildings and surroundings, the determination of optimal evacuation routes etc.

The aim of this project is to develop a simulator that can be used for interactive training of the staff responsible for evacuation in emergency situations and perform what-if analyses of different evacuation options. For this purpose large pedestrian crowds have to be simulated in real-time or even faster.To satisfy these conditions the simulator is based on a cellular automata combined with a force model. This force model basically relies on the computation of po­ten­tial fields representing the repulsive forces of obstacles and other pedestrians and the driving term of the destination.This basic structure is extended by a visibility graph. This approach enables a faster adaptation according to online variation of the simulation scenario (e.g. closing a door during simulation). The basic idea is to generate a graph from the scenario’s topography, which represents the entire set of possible pedestrian routes.One of our objectives in this project is to identify different pedestrian way finding strategies. For the implementation of these different behaviors we use the graph by implementing different routing strategies.This project is conducted in strong collaboration with Siemens AG.
