Beschreibung
Increasing number of visitors at large-scale events combined with the increasing complexity
of modern buildings set a major challenge for planners, operators and emergency services.
Examples include multi-purpose arenas, large railway stations and airports. In this dissertation
the use of modern parallel hardware in combination with optimised algorithms are for the first
time used on site to speed up the simulation of large crowds. The aim is to perform real-time
forecasts of pedestrian traffic. For this purpose, special neighbourhood lists and a two-stage
hybrid parallelisation are used. The second part of this dissertation deals with route choice in
complex structures, which plays an important role in achieving realistic computer simulations of
pedestrian flows. The developed route choice process is based on visibility and perception of the
local environment by the simulated agents. It has as basis a navigation graph. The generation of
the graph, especially in complex structures, has also been performed within the framework of this
thesis. The work is closed with an empirical study in which the route choice profiles of spectators
during various football games and concert performances are analysed and compared with
the proposed model.The runtime optimisation strategies and route choice algorithms have been
successfully tested in the ESPRIT arena in Düsseldorf (Germany), where they have been
integrated in an evacuation assistant.
