TLDR
The data (spatial and non-spatial) requirements and a database for wheelchair navigation are discussed and the experience in constructing a spatial database of the University of Pittsburgh campus area for wheelchair Navigation is reported.Abstract:
A spatial database is an essential part of a navigation system since it provides the necessary resources to perform navigation and routing functions, among others. While generally wheelchair navigation and car navigation overlap from the functional standpoint, databases for car navigation are not suitable for wheelchair navigation. One major difference between databases for car navigation and wheelchair navigation is that operations in car navigation are centered around road networks along with road segment attributes, whereas operations in wheelchair navigation are primarily centered around sidewalk networks along with unique parameters related to accessibility information about the surrounding environment. In this paper, we discuss the data (spatial and non-spatial) requirements and a database for wheelchair navigation. We also report our experience in constructing a spatial database of the University of Pittsburgh campus area for wheelchair navigation.read more

Pedestrian network map generation approaches and recommendation
TL;DR: Three approaches, network buffering, using existing road networks, collaborative mapping, using Global Positioning System (GPS) traces collected by volunteers, and image processing, using high-resolution satellite and laser imageries, are viable for automatic pedestrian network map generation.

Personalized accessibility map (PAM): a novel assisted wayfinding approach for people with disabilities
TL;DR: Accessibility requirements published in the literature, the criteria used in existing geo-crowdsourcing services and the data used by campus accessibility maps are used to provide an optimal set of requirements for personalized accessibility map (PAM).

A fuzzy logic map matching for wheelchair navigation
Ming Ren,Hassan A. Karimi +1 more
TL;DR: A fuzzy logic-based algorithm is applied to effectively perform matching wheelchair movements on sidewalks to overcome difficulties in tracking wheelchairs in urban areas due to poor satellite availability.

TL;DR: It is suggested that efforts to facilitate social participation by wheelchair-users should focus not only on the built environment, but also on interventions in personal assistance and assistive technology, health promotion and fitness, and programs that improve civility.

Mapping for Wheelchair Users: Route Navigation in Urban Spaces
TL;DR: A Geographical Information Systems (GIS) network model for the creation of accessibility maps for wheelchair users is developed, providing a tool suitable to assist wheelchair users new to an area; to enable better navigation for existing users; and a means for planners to consider the way in which access is restricted for wheelchair Users in their designs for more inclusive urban environments.

TL;DR: U-Access, as a routing tool, provides pedestrians with the shortest feasible route with respect to one of three differing ability levels, namely, peripatetic (unaided mobility), aided mobility, aided mobility and wheelchair users.
