Navigation infrastructure for people with disabilities

The importance of navigation support for people with disability has been demonstrated by convention on the Rights of Persons with Disabilities. This paper presents the navigation infrastructure for people with disabilities. The infrastructure includes map generation service, web interface, mobile services. Also we purpose method of target area examination by volunteers. Using a modified Openstreetmap road graph allows you to build more precise routes. Introduced classification of obstacles types allows you to identify problems in the path of a person with disabilities. Application of Dijkstra's-based algorithm with modified edge weights allows you to find safe traffic routes. The results of testing on the pilot region allow us to estimate the amount of work required to improve the quality of people's live with disabilities
