\caption{Simple staircase scenario to compare the graph-based model with the navigation mesh. The black line indicates the current position and the green line gives the estimated path until 25 or 180 steps, both using weighted average. The particles are coloured according to their height. A pedestrian walks up and down the stairs several times in a row. After 25 steps, both methods produce good results, although there are already some outliers (blue particles). After 180 steps, the outliers using the graph have multiplied, leading to a multimodal situation. In contrast, the mesh offers the possibility to remove particles that hit a wall and can thus prevent such a situation.}

To make a statement about the performance of our novel transition model presented within section \ref {},
we chose a simple scenario, in which a tester walks up and down a staircase three times.
\todo{speicherbedarf zwischen grid und treppen}
fig shows a situation in which the new transition model is able to perform better due to choosing a clever tactic in this situation.
particles hitting a wall are remove, while on grid we do not know if a wall is hit, since particles can only move on nodes and search for neaboring nodes..
at 25 can see that some particles walking nach oben both scenarios..
at 180 in grid das fehlverhalten kummuliert während bei der coolen taktik der neuen transition nicht.
of course, can be fixed adding an activiy if up or down or incorporating a barometer.
aber es ist eine gute sache wenn ein sensor für sich schon gute ergebnisse liefert.
er wird dadurch unabhängiger und kann beim ausfall der anderen sensoren tdz. gute ergebnisse liefern.
weiterhin, neue transition more continues etc pp.
der speicherbedarf von --- nach ---, voll toll und praktisch.
