An overpass-based map that shows wheelchair-obstacles. It can be viewed here on github.io.
It is based on the TransforMap demo Maps. It is 'forked' from this point in time.
for performance reason, the data displayed is a static file, only updated once in a while from overpass api.
Update:
wget -O normal.json --post-file=normal.query "http://overpass-api.de/api/interpreter"
wget -O athletic.json --post-file=athletic.query "http://overpass-api.de/api/interpreter"
wget -O electro.json --post-file=electro.query "http://overpass-api.de/api/interpreter"
