Google Biking

Google Maps gets biking directions: http://googleblog.blogspot.com/2010/03/biking-directions-added-to-google-maps.html

Dark green routes are dedicated bike trails and sidepaths; light green are bike lanes, and dashed green lines are "recommended" roads for biking.

I haven't explored it much yet to see what I think of the actual routes it suggests.  It seems to recommend bike paths and lanes strongly over other roads, which is fine, but of course it can't really take things like road surface quality into account.

If people with phones that have accelerometers and GPS were willing to share the data, you might be able to estimate bumpiness of ride.

Oh, good point. I was thinking of GPS logs mostly as a source of what routes and turns people chose to follow in practice, but it probably could track bumpiness too.
