People for Bikes, a large industry-sponsored advocacy org in the US has put money forward to take the concept of "Traffic level of stress" and then use OSM-data to calculate whether a specific street and intersection is low-stress or high-stress. You can find a SOTM-US talk about the "Bicycle Network Analaysis" project here: https://2017.stateofthemap.us/program/bicycle-network-analysis.html https://bna.peopleforbikes.org/#/ The bike advocacy group I'm involved with here in Madison (WI) has been using the map/data generated through the Bicycle Network Analysis process, and we're working on a validation process to a) figure out where our local knowledge disagrees with the calculated stress value and then b) figure out whether that's an issue of the underlying OSM data (spoiler alert: in many cases it is) or a different issue. Happy to answer any questions about this. Harald (formerly Montreal, and therefore still subscribed to talk-ca)
