I'm looking for a data-driven way to virtually assess accessibility of sidewalks in California, particularly in the Bay Area. Basically, any tools that would help with estimating a 'walkscore' type of rating for sidewalks would be ideal.

FYI - There is a group of researchers at UMD doing something similar for sidewalks in Washington DC. Here's the link: http://sidewalk.umiacs.umd.edu

If you know any tools/ resources/ contacts who would be useful or can point me in the right direction, please let me know.

Thanks in advance!

wheelmap is exactly that, built atop osm and open source.


A team at Georgia Tech did an app measuring sidewalk quality based on crowd sourced data.



Here are some resources:
