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

摘要

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 4point tiedown system, a prototype autodocking system, and a prototype rearfacing wheelchair passenger (RFWP) system. Study participants took a 15minute city ride and completed a survey. Participants responded positively to the autodocking and RFWP systems that were quicker and easier to use and allowed more independent use than the 4point tiedown system (p < 0.001). There was concern regarding the RFWP system that rearfacing travel made it more difficult to see upcoming stops and was less comfortable than a forwardfacing 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 forwardfacing travel. Participants found it undesirable, however, that a wheelchairmounted docking adaptor was needed to use the autodocking system. Study results indicate a need for improved securement systems for forwardfacing use that do not require a wheelchair adaptation and can be easily and independently used by wheelchair and scooter users.
