ROUTE4ALL: a novel approach to pedestrian navigation for people with special needs

Within ROUTE4ALL project we created an extended data model of geographical information database suitable for navigation of people with special needs as well as of general population. Moreover, we provide a methodology for its interpretation and a guide for its implementation into navigation devices. The results of the project could be used by navigation device developers for creating a fully-fledged navigation for people with special needs. First, we describe the requirements for the extended data model, which rise from the research we conducted with people with special needs and from the survey of existing solutions. Second, we introduce a catalogue of geographic elements, their attributes and relationships. Finally, we discuss its benefits over the traditional approaches.
