Wheeled mobility device database for transportation safety research and standards

Area of Science:

• Rehabilitation Engineering
• Biomechanics
• Transportation Safety

Background:

• Limited data exists on current wheeled mobility devices (e.g., wheelchairs) for vehicle integration.
• Safe and accessible transportation is a critical need for users of mobility devices.
• Existing vehicle access and securement methods may not accommodate diverse device designs.

Purpose of the Study:

• To establish a comprehensive characterization scheme for wheeled mobility devices.
• To develop a database for storing frame characteristics relevant to vehicle access and securement.
• To provide data for improving safety standards and assistive technologies for transportation.

Main Methods:

• Defined key frame characteristics of wheeled mobility devices.
• Developed a structured database for recording these characteristics.
• Surveyed a representative sample of current-production devices to gather data.
• Performed descriptive statistical analysis on the collected measurements.

Main Results:

• A detailed frame characterization scheme was successfully developed.
• A database containing measurements for numerous wheeled mobility devices was populated.
• Descriptive statistics highlight the variability in device characteristics relevant to securement.
• The data provides a foundation for understanding device-specific securement challenges.

Conclusions:

• The developed database and characterization scheme are essential for advancing research in accessible transportation.
• This data is actively used to inform the development of new technologies and safety standards.
• Future applications include improving vehicle design and enhancing user safety during transport.
