Hey, I'm a GIS noob, but I was recently overcome with a desire to see
a bicycle directions button on the Google Maps page, so I started to
poke around to see what has been done in terms of bicycling routing,
and open source routing in general.
Hi Jessica,
I'm not sure where you're located, but my research group is working on a
fairly advanced bicycle route-planning system, focusing on
Minneapolis-St. Paul for now. We'll have community features as Rich
suggested and lots of other great stuff. We hope to be live this fall,
and it will be open source eventually.
As others have noted, the routing is easy (A* search is preferable to
Dijkstra's algorithm) but getting the data is hard. Even if you have the
locations of all the bike facilities, those aren't necessarily the best
ways to go, and a good route depends on individual purpose and
preferences as well. It's actually a rather hard problem.
If you like, I'd be happy to send you updates on our system once things
start getting interesting.
Take care,
Reid
