Intermodal Door-to-Door Routing for People with Physical Impairments in a Web-based Open Source Platform

摘要

The needs of people with disabilities are addressed by the United Nations “Convention on theRights of Persons with Disabilities” with the intent to allow people with disabilities for equalparticipation in societal activities as people without disabilities. This research follows the aim ofthe UN convention by developing a geospatial barrier catalog and implementing a prototype of aWeb-based intermodal door-to-door routing application for people with physical impairments.Within the geospatial barrier catalog objects and structures, built in indoor or outdoorenvironments, are outlined regarding their influence on the intermodal locomotion of people withphysical, visual, and hearing impairments. The spatial representation of the catalog ismaterialized through a data model within the OpenStreetMap (OSM) framework. Based on thedata model indoor and outdoor data were collected for the inner city of Villach, Austria, as astudy area. The prototype uses a customized version of the open-source intermodal trip plannerOpenTripPlanner (OTP) which supports trip planning for walking in combination with publictransportation, including transition-free routing between indoor and outdoor environments. Thefunctionality of the trip planner is illustrated for two scenarios.
