Group dynamic behavior and psychometric profiles as substantial driver for pedestrian dynamics

Our current research lays emphasis on the extended pedestrian perception and copes with both the dynamic group behavior and the individual evaluation of situations, and hence, rather focuses on the tactical level of movement behavior. Whereas common movement models primary consider operational aspects (spatial exclusion or distance and direction related repulsion), the consideration of psychophysical concepts and intra-group coordination overcomes the idea of directed repulsion forces and derives specific movement decision with respect to the individual evaluation of situations. To provide a solid basis we analyze both data recorded at a mass event and data from a double-staged evacuation test to derive essential group dynamic behaviors and psychological related decision principles, respectively.
