[Talk-transit] GTFS and the like

[Jan]

Hi,

I don't know how it work in these program, but there are too ways. The
easiest one is to get the stops and find ways from one to the next. This
is easy because you have to solve only one problem and the the next. But
its not very good. Because the next way would be much longer or
imposible if you reach the stop from the wrong site. Maybe it's better
to make indirection and have less poblems later.

These is posible if you have all stops and make a matching to all
posible points around your stops.

regards Jan
