  • My friend Herbie asked some excellent questions about how and how well Google's Bike There program generates bike routes on her blog. She notes,

Can we tell what Google's routing criteria are based on the routes it suggests? If they have some magic routing algorithm for bicycling I most definitely want to see it. My guess is that it (1) routes on city-designated bike lanes, paths, and routes, whenever possible, and has some tolerance for routing out-of-the-way (i.e. away from the shortest distance path) to get on them. It has some trade off between hilliness and directness built in. It knows major boulevards and avoids them. What else?
