User evaluation of three wheelchair securement systems in large accessible transit vehicles

Abstract

Ease of use, comfort, security, and independent use of three types of wheelchair securement systems were evaluated in a large accessible transit vehicle by 20 wheelchair and scooter users. The securement systems included a 4-point tie-down system, a prototype autodocking system, and a prototype rear-facing wheelchair passenger (RF-WP) system. Study participants took a 15-minute city ride and completed a survey. Participants responded positively to the autodocking and RF-WP systems that were quicker and easier to use and allowed more independent use than the 4-point tie-down system (p < 0.001). There was concern regarding the RF-WP system that rear-facing travel made it more difficult to see upcoming stops and was less comfortable than a forward-facing ride and that the system may damage wheelchair wheels during use. The majority of participants preferred using an autodocking system because it allowed secure and independent forward-facing travel. Participants found itundesirable, however, that a wheelchair-mounted docking adaptor was needed to use the autodocking system. Study results indicate a need for improved securement systems for forward-facing use that do not require a wheelchair adaptation and can be easily and independently used by wheelchair and scooter users.
