3. Empty blocks (buildings with zero levels) modelling squares, parks, etc,
which have the current unlimited restrictions.

Addition:
 From research point of view I would also like to add rescue agents halfway
a simulation, so that the teams have to be reconfigured.

Not against.
This feature is strongly related with the traffic direction acti
