[Freegis-list] city bus routes

The following message is a courtesy copy of an article
that has been posted to sci.geo.cartography as well.

Here's a note I sent to the GRASS-GIS mailing list:
Just curious if I'm barfing up the wrong tree or can Grass be used to
find what buses should I consider from going from point A to point B?

Say for Taibei, Taiwan we program in all the spaghetti of routes and
even maybe the position of their bus stops.  Then we say "please find
which routes pass within 500 meters of both point A and B".  This
might give 3 or 4 routes for the rider to then select from based on
non GIS criteria.

Actually I think the best way to deal with this problem is not via
computer at all, but with close up maps where the user can match route
numbers.  Nothing as high tech as a cross referencing index involved.
And certainly no "need a computer to catch a bus".  If they were
computer savvy they wouldn't be on the bus in the first place... [ok,
yes, even Einstein took buses probably, never mind.]
