The intensity of movement through an doorway is determined by the local density in front of the doorway, the width of the opening, and the type of people (contingent).
Additionally, the movement intensity through the doorway is limited by the maximum possible throughput capacity of the doorway. In the current version of Fenix+, this parameter is hardcoded and cannot be modified.
$q_{max}=19.6 m/min$
In addition, when high flow density forms in front of an doorway ($D>0.5 m^2/m^2$), the throughput capacity of the doorway decreases due to the “false doorway” effect.
This phenomenon is accounted for by introducing an additional multiplier $m$ into the speed–density relationship:
$m = 1,25 – 0,05·D$
When the maximum flow density is reached in front of the doorway, the movement intensity through the doorway no longer depends on the contingent of people and is determined only by the width of the doorway $W$:
