Problem ID: A1CC-89C3-E0EF-7B06
Your report:The directions suggest a route that is much more unsuitable for biking than an alternative route just near the one google suggests. I am not sure if this is out of the scope of your capabilities, but average daily traffic on Olympic (the road suggested) is much, much more than ADT on 9th, which is just North of Olympic. If I were giving bicycling directions I would suggest 9th.
Thanks for your help,

Do folks out there know of other crowdsourced bike route databases? I'm intrigued by the idea, since lots of bicyclists I know choose their routes based on word-of-mouth. The complexity of the route data seems to resist an internet platform: for example, I'll get word that a certain street is good to ride on, except during rush hour; or vice versa - some streets aren't bad to ride on during rush hour because they are so congested; or I'll get word that I should avoid a street at night, etc. Nonetheless, I think crowdsourcing has been both effective and self-reinforcing in Google's case. I've noticed an uptick on Carmelita Ave. (near UCLA, parallel to the much crappier Santa Monica Blvd through Beverly Hills) in particular, and at least one rider told me she learned about the street through Google biking directions. But Google's routes are not openly crowdsourced, they're controlled internally. When I have time I want to learn more about true and open crowdsourced bike route programs and how they perform. Thoughts?
Also, how do folks out there think Google's "Bike There" option is performing in LA? What are places where Google really gets it right? Or wrong?
Hmm... and: 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?
