I know there is a bikeability and walkability score online, but when I move to those places I find mostly recreational biking paths and unprotected bicycle lanes doing most of the heavy lifting, they don’t have very many bike lanes that actually go anywhere like businesses, public transportation, hospitals, gyms, or entertainment facilities.
Is there a metric for that or a website that tracks actual usability of bike and walk routes and maybe even their safety features?
Seconding the openstreetmap recommend, because there are multiple types of cycling facility definitions in the OSM spec that can more specifically describe the quality of the infrastructure.
