Our mission: map and assess the world's sidewalks using remote crowdsourcing, artificial intelligence, and online satellite & streetscape imagery. Let's make the world more walkable, rollable, and bikeable! Join us: https://projectsidewalk.org/
We're now working on incorporating RampNet into Project Sidewalk. Let's go! 🚀 Shoutout to the whole team, including John, @jaredhwang.bsky.social, Zeyu Wang, and @ismikey.bsky.social. CC @uwcse.bsky.social

Curb ramps are critical for mobility—for wheelchair users, parents with strollers, travelers with luggage. But detecting them automatically in images is an open problem. We've been working on automatic curb ramp detection for over 10 years, and RampNet significantly outperforms our prior work!

to use this unprecedented data to design, develop, and evaluate next-generation mapping tools.

We have mapped sidewalk accessibility in 28 cities across 8 countries including the US, Canada, Mexico, Ecuador, Netherlands, & New Zealand covering nearly 20,000km. Join us: projectsidewalk.org
