REPKA - Regional Evacuation: Planning, Control and Adaptation

Inhaltsbereich / Content

REPKA - Regional Evacuation: Planning, Control and Adaptation

Motivation

One of the basic rescue measures in the case of attacks, attack threats, large-scale accidents and natural disasters is the evacuation of the affected buildings and regions. In this context, the overarching goal is to evacuate affected persons as fast and reliable as possible. This project is primarily concerned with regional evacuation. In particular, it will examine the situation that occurs when a large crowd has alread left a building and must be brought further away to safety. The research hinges on the results of building evacuation, thereby bridging an important security gap.

Our Contribution to REPKA

We generate data, such as pedestrian velocity (free-flow and in groups) and the utilization of routes after a soccer match around the stadium. Video analysis, several exercises and surveys are conducted to yield these necessary information. Developing a mathematical node-arc-model from the map of the area Betzenberg is another important step. To the resulting graph we apply dynamic network flow algorithms, e.g. a quickest flow algortihm. The solution of this algorithm is the minimum time needed to lead people to safe places. It further gives information about potentially overcrowded roads or critical junctions. To visualize our solutions we project the network onto the map again thereby coloring each arc depending on its load.
