Dear Stefan,

could you please keep the discussion on the list? Others could be
interested as well.

Bus stations and bus lines can be omitted. 

In contrast, the present model depends on street attributes. If you do
not give the necessary attributes of a street, the street is empty. No
one lives there. The model also needs schools to make the children have
an activity during the day.

Well, while the model considers walking, it does not generate walking
routes at present, unfortunately. This would certainly be a good
extension.

The transportation means are computed in the class AGActivity and
selected in AGWorkAndSchool. You could look there for an easy extension.

Best regards,

Simon
