Abstract |
Design challenges in wheelchair securement for fixed-route, large accessible transit vehicles (LATVs) often create difficulties for passengers who use wheelchairs and operational inefficiencies for public transit agencies. Recent innovations in wheelchair securement technology for LATVs may reduce these challenges. This study explored the usability of three commercially available wheelchair securement systems in a static laboratory environment: a four-point, forward-facing (4P-FF) securement system, a three-point, forward-facing (3P-FF) securement system, and a semi-automated, rear-facing (SA-RF) securement system. Three groups of mobility device users (manual wheelchair users, power wheelchair users, and scooter users) (n = 36) completed wheelchair securement tasks in a full-scale mock-up of an LATV. For the 19 participants who did not use the occupant restraint system (ORS), perceived usability and securement time were compared across the securement systems. Using multiple usability rating scales, most participants reported that each of the systems would be acceptable for regular use. However, the majority indicated an overall preference for the SA-RF, and most rated the SA-RF system as easier, faster, and requiring less assistance to use than the 4P-FF and 3P-FF systems. Alternatives to conventional 4P-FF wheelchair securement in LATVs may thus improve boarding efficiency and transit independence of passengers who use wheelchairs. Language: en |
