Investigating challenges and designing solutions for accessible public transportation for wheelchair users

Abstract

This thesis investigates the challenges and technological solutions for empowering travelers with temporary mobility impairments within the Dutch railway systems. Despite the extensive use of railways in the Netherlands, accessibility issues persist, particularly for those with temporary disabilities resulting from injuries, surgeries, or short-term health conditions. The research highlights the significant barriers and travel needs of these individuals, captured through interviews. Using a user-centered design approach that incorporates these challenges and needs, this study identified technological accessibility features to enhance perceived accessibility and independence for temporarily mobility-impaired travelers, thereby improving their overall travel experience. Key solutions include real-time updates on station crowding and elevator functionality, and a location based immediate assistance button. By implementing these features, the redesigned NS Planner aimed to provide a more accessible and autonomous travel experience. The evaluation of these features through vignette studies showed significant improvements in travel autonomy and promising enhancements in perceived accessibility and travel experience. This research not only contributes to the field of Human-Computer Interaction but also offers practical insights for developing accessible transportation systems globally, ensuring that public transport becomes more inclusive for all individuals with mobility impairments.
