We are happy to announce that the first version of the wheelchair routing profile is now available online within OpenRouteService and goes into beta testing phase. Currently, there is a separate version (http://openrouteservice.org/
In the pictures at http://giscienceblog.uni-hd.
IMPORTANT: There is a huge lack of data about sidewalks and footways/paths, such as surface, smoothness, incline and also dropped kerbs. However, this information is necessary to compute optimal routes for wheelchair users. Since the quality of the computed routes can only be as good as the underlyingOpenStreetMap data that is used, we are calling the OSM contributor crowd to help improving this situation!
If you want to know, where contributions are still needed – in fact they are needed in most areas ;) -, we highly recommend the OSM Quality Assurance Editorthat has been developed by the OSM user nitegate (aka Adrian Stabiszewski) with some extensions from our side. In the current version, this tool shows you e.g. streets that do not have any sidewalk tags yet, ways without an incline tag and also ways without surface/smoothness tags. The latter two will need to be extented to surface and smoothness tags specifically of sidewalks in the future. As you can already judge from the name, the quality assurance editor allows you to directly edit identified ways where data is still missing using your OSM account.
