PREDICTION OF EVACUATION FROM A LARGE-SCALE ASSEMBLY FACILITIES APPLYING MULTI-AGENT MODEL: Validation study of pedestrian simulation system SimTread in practical use

The purpose of this paper is to examine the prediction performance and practical usability of Multi-agent pedestrian simulation system. As an example, evacuation flow of about 10000 people from large-scale assembly facilities is simulated. Major results are as follows; 1) At the seats lined up orthogonally to the aisle, farther seats from egress of aisle remains to the last. 2) At the point two pedestrians flow merges, the flow become more densely. 3) In case flow become densely, if there is extra space, pedestrians expand the walking area and decrease density to walk by maximum speed. Those features are described quite obviously as movies and a lot of perceptions are acquired which cannot be acquired by conventional evacuation calculation methods.
