The "Accessible Routing" project ([1]) aims at developing an accessible web service for route planning on the web. The geocoding and routing services as well as hosting are currently provided by OpenRouteService. Contact person is the user Ant. Actually, this project only works for Germany.

Project description

"Accessible Routing" is a web portal for accessible route planning. The web site allows to generate a route description for a desired pedestrian route - in plain text or in an embosser-ready braille format. Start and end locations are entered as adresses, the output contains a description where to turn in which street and what distance is left until the next turn.

Most routing services on the web are reserved for seeing people, because they use graphical interaction, such as maps, or excluding technologies, such as JavaScript and Flash. For this reason our focus is on designing a web site for all that can be used with refreshable braille displays and screen readers.

In upcoming releases the route description shall be more detailed. They will contain hints for orientation and special points of interest for the blind, such as tactile pavings.

Another idea is the conception of a user terminal in public space that allows passersby to get route descriptions to their desired destinations immediately.

Project status


The first prototype is ready. Web:


  • calculation of any desired pedestrian within Germany
  • plain text input and output
  • text output in embosser-ready grade 1/grade 2 braille
  • black and white mode
  • multiple languages (so far only English and German)

Upcoming features

  • Routing conforming to the needs of the visually impaired
  • Visual map interface
  • ...
