      abstract     = {Force-based models describe pedestrian dynamics in analogy
                      to classical mechanics by a system of second order ordinary
                      differential equations. By investigating the linear
                      stability of two main classes of forces, parameter regions
                      with unstable homogeneous states are identified. In this
                      unstable regime it is then checked whether phase transitions
                      or stop-and-go waves occur. Results based on numerical
                      simulations show, however, that the investigated models lead
                      to unrealistic behavior in the form of backwards moving
                      pedestrians and overlapping. This is one reason why
                      stop-and-go waves have not been observed in these models.
                      The unrealistic behavior is not related to the numerical
                      treatment of the dynamic equations but rather indicates an
                      intrinsic problem of this model class. Identifying the
                      underlying generic problems gives indications how to define
                      models that do not show such unrealistic behavior. As an
                      example we introduce a force-based model which produces
                      realistic jam dynamics without the appearance of unrealistic
                      negative speeds for empirical desired walking speeds.},
