This is an animation to support a contribution to the 92nd edition of the Transportation Research Board meeting (TRB 2013) titled "Multi-Directional Flow as Touch-Stone to Assess Models of Pedestrian Dynamics".

00:09 Part I: Three animations of simulation runs with identical parameter settings but different random number generator seed value. The particularly relevant parameters g and h here have values of g=1.0 and h=1.0. It can be seen that with these parameters randomly left-turning and right-turning rotation occur, but occasionally the simulation also does not develop a visible rotation direction.

00:51 Part II: Three animations of simulation runs with identical parameter settings but different random number generator seed value. The particularly relevant parameters g and h here have values of g=1.0 and h=1.0. The left animation shows a run with a pronounced rotational movement, but - against the general correlation - with rather high average and maximum walking times. The center shows a simulation run exhibiting the opposite: weakly pronounced rotational movement, but rather small average and maximum walking times. The right side shows a simulation run where measure A is positive, while measure P is negative.

01:33 Part III: The left side shows what happens if the value of parameter g is set to g=0.0. The center shows a simulation run with g=1.0 and h=0.0 and the right side shows a simulation run with the parameter choice which has been mainly investigated in the paper: g=1.0 and h=1.0.
