The input describes
|
||
an exact number of people, who live in one zone and work in another (possibly the same) and
|
||
commute using some mode. For each of them, we just need to pick a specific home and workplace
|
||
from the zones, and use the Options to pick departure times. We’ll wind up creating people who
|
||
just take two trips daily: home -> work -> home.</p>
|
||
<p>The home and workplace may be a specific building, or they’re snapped to a map border,
|
||
resulting in trips that begin and/or end off-map. The amount of the zone that overlaps with the
|
||
map boundary determines this. If the zone and map boundary overlap 50% by area, then half of
|
||
the people to/from this zone will pick buildings, and half will pick borders.</p>
|
||
<p>Currently, zones with no overlap with the map at all are totally filtered out. We could adjust
|
||
this in the future to create more highway through-traffic.</p>
