“…Based on the specification, some of the recommended parameters that need to be implemented in the final dataset can be surface information, incline and width of the sidewalk segment. However, based on a number of other studies [29,[37][38][39], additional parameters for a disabled friendly routing network have been determined which would are later introduced in Section 3.…”

Nowadays, Volunteered Geographic Information (VGI) has increasingly gained attractiveness to both amateur users and professionals. Using data generated from the crowd has become a hot topic for several application domains including transportation. However, there are concerns regarding the quality of such datasets. As one of the most famous crowdsourced mapping platforms, we analyze the fitness for use of OpenStreetMap (OSM) database for routing and navigation of people with limited mobility. We assess the completeness of OSM data regarding sidewalk information. Relevant attributes for sidewalk information such as sidewalk width, incline, surface texture, etc. are considered, and through both extrinsic and intrinsic quality analysis methods, we present the results of fitness for use of OSM data for routing services of disabled persons. Based on empirical results, it is concluded that OSM data of relatively large spatial extents inside all studied cities could be an acceptable region of interest to test and evaluate wheelchair routing and navigation services, as long as other data quality parameters such as positional accuracy and logical consistency are checked and proved to be acceptable. We present an extended version of OSMatrix web service and explore how it is employed to perform spatial and temporal analysis of sidewalk data completeness in OSM. The tool is beneficial for piloting activities, whereas the pilot site planners can query OpenStreetMap and visualize the degree of sidewalk data availability in a certain region of interest. This would allow identifying the areas that data are mostly missing and plan for data collection events. Furthermore, empirical results of data completeness for several OSM data indicators and their potential relation to sidewalk data completeness are presented and discussed. Finally, the article ends with an outlook for future research study in this area.

“…Travelling is a laborious task for wheelchair users, especially in unfamiliar environments, because they have to overcome an array of interpersonal and environmental barriers (Ding et al 2007, Volkel et al 2008. In a study conducted by Meyers et al (2002), 28 adult wheelchair users were interviewed and it was found that the barriers frequently reported included narrow sidewalks, no ramps or steep ramps, no sidewalk curb cuts, poor sidewalk surfaces and sidewalk obstructions.…”

Wheelchair users are confronted with many outdoor obstacles in everyday travel that can make the task arduous and unsafe, especially in unfamiliar environments. However, if wheelchair users are provided with routes that can safely, accurately and efficiently guide them to their destinations, then the difficulty and danger associated with traveling might be significantly reduced. In this article, we present a routing method suitable for wheelchair users by taking into account sidewalk obstacles such as slope, steps, sidewalk condition and sidewalk traffic as are preferred by users. Our method calculates impedance scores for each sidewalk segment, which are then used to determine an optimal route between any given pair of origin-destination addresses in a sidewalk network. We first discuss sidewalk network parameters and a spatial database suitable for wheelchair navigation. Then we discuss our personalised routing approach. We also describe three methods to weight the impedance level of each sidewalk segment and compare the effectiveness of each method through experimentation using the sidewalk network for the University of Pittsburgh campus area.

“…Design considerations for personalized wayfinding and navigation technology for WCU were discussed in [31] but no comprehensive system has been developed yet. Key considerations of the design include: requirements that the map database include location-based accessibility features, such as sidewalk conditions; personalized route planning algorithms that can be accomplished based on the users functional level and preferences; and positional accuracy within 3 meters.…”

“…No validation of the accuracy of the site assessments have been performed, so the reliability of the data is unclear. Finally, the three levels of accessibility (accessible, limited accessibility and non accessible) provides only a generic assessment would does not include the level of detail commonly noted to be necessary for wheelchair route planning [31] and [42].…”

To achieve safe and independent mobility, people usually depend on published information, prior experience, the knowledge of others, and/or technology to navigate unfamiliar outdoor and indoor environments. Today, due to advances in various technologies, wayfinding and navigation systems and services are commonplace and are accessible on desktop, laptop, and mobile devices. However, despite their popularity and widespread use, current wayfinding and navigation solutions often fail to address the needs of people with disabilities (PWDs). We argue that these shortcomings are primarily due to the ubiquity of the compute-centric approach adopted in these systems and services, where they do not benefit from the experience-centric approach. We propose that following a hybrid approach of combining experiencecentric and compute-centric methods will overcome the shortcomings of current wayfinding and navigation solutions for PWDs.
