Pedestrian pathway characteristics and their implications on wheelchair users

Area of Science:

• Biomechanics and Rehabilitation Engineering
• Human Factors and Ergonomics
• Transportation Engineering

Background:

• Wheelchair users frequently encounter uneven and rough surfaces, posing risks to comfort and physical well-being.
• Current pathway design standards may not adequately address the specific needs and challenges faced by wheelchair users.
• Understanding the impact of surface characteristics is crucial for ensuring equitable and safe mobility.

Purpose of the Study:

• To review existing research on the effects of surface roughness on wheelchair users.
• To evaluate measurement techniques for characterizing pedestrian pathway roughness.
• To identify gaps and opportunities for improving design guidelines and exposure limits for wheelchair accessibility.

Main Methods:

• A comprehensive literature search was conducted to gather relevant studies.
• Existing measurement and analysis techniques for road roughness were reviewed for their applicability to pedestrian pathways.
• Focus was placed on identifying methods suitable for characterizing surface profiles relevant to wheelchair dynamics.

Main Results:

• Several techniques exist for measuring road roughness, but systematic application to wheelchair pathways is limited.
• Rolling profilers and International Roughness Index (IRI) analysis show promise for adaptation to pedestrian surfaces.
• Frequency and wavelength analyses relevant to wheelchair dynamics are key considerations for adapted techniques.

Conclusions:

• Existing road roughness measurement techniques can be adapted for assessing pedestrian pathways for wheelchair users.
• Further research and development are needed to refine measurement protocols and establish specific design guidelines.
• Improved characterization of surface roughness will enhance the safety, comfort, and accessibility of public and private pathways for wheelchair users.
