Object tracking typically relies on a dynamic model to
predict the object’s location from its past trajectory. In
crowded scenarios a strong dynamic model is particularly
important, because more accurate predictions allow for
smaller search regions, which greatly simplifies data association.
Traditional dynamic models predict the location
for each target solely based on its own history, without taking
into account the remaining scene objects. Collisions
are resolved only when they happen. Such an approach
ignores important aspects of human behavior: people are
driven by their future destination, take into account their
environment, anticipate collisions, and adjust their trajectories
at an early stage in order to avoid them. In this work,
we introduce a model of dynamic social behavior, inspired
by models developed for crowd simulation. The model is
trained with videos recorded from birds-eye view at busy
locations, and applied as a motion model for multi-people
