  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.
