Development of Surface Roughness Standards for Pathways Used by Wheelchair Users: Final Report

Questionnaire

A full version of the questionnaire given to the subjects after traveling over each surface can be found in Appendix C. The questionnaire was developed by the study investigators. The first question, shown in Figure 4, was based on ASTM 1927-28: Standard Guide for Conducting Subjective Pavement Ride Quality Ratings. This standard, which will be described later, is used to conduct subjective ratings of roadways so it was used in the same manner to conduct subjective ratings of our engineered and outdoor surfaces.
