Using different population classes

[rashidzetter]

I wonder how the script can be easily adapted to use a different population classification; instead of using workers, students, and inactive users classes, I want to see the simulation results from multiple distance classes (e.g., <5km from work/school, 5-20 km, and >20km). How hard can it be to use at least three distance classes?, wherein the time windows and other required parameters are calculated based on the distance groupings from the survey/census data.
