Ride the City - Maps working in Open Source having impacts

Ride the City uses map data from the crowd sourced Open Street Map project — which includes bicycle paths, bike lanes, and other bicycle facility data — to generate “safer, safe, and direct” routes for bicyclists in Austin, Chicago, DC Metro, Louisville, New York City, San Diego, Seattle, and now Toronto.

Unlike Google’s One Size Fits All approach of assigning a very high preference to bike paths over direct street routes, Ride the City gives riders the choice of selecting “safer,” “safe,” and “direct” routes. “Safer” assigns a high preference for bike facilities over direct road routes; “safe” programs a moderate preference, and “direct” calculates a direct route without any consideration for bike paths and lanes. (Aside: RtC is a very cool service, but I really wish they’d use different nomenclature. Labeling bike facilities as “safe” is, at best, misleading, partly because that implies roads are unsafe and partly because facilities aren’t necessarily safer.)
