It also needed to be one that could be used by a person in a mobility aid with little or no assistance from the bus driver. Next, a survey was conducted of existing securement systems. Several problems were identified with existing securement technology. The data indicated that, even with training, it takes several minutes to properly apply standard belt securement systems. What they found was the users and the drivers were uncomfortable with the strap systems.
Straps are cumbersome and often require assistance to secure.
Both user and driver wanted a system that most passengers could secure themselves. Baseline requirements were developed from the research, which like the OSU project, clearly pointed to a docking approach as the only feasible universal securement methodology. It is a term borrowed from the space program. According to Reger, the same idea is behind wheelchair docking. Any kind of wheelchair can make contact and become attached solidly to the mother device.
