STUDY ON THE RELATIVE EVALUATION METHOD OF SLIPPERINESS OF FLAT AND INCLINED FLOORS AND PAVEMENTS FROM A VIEW POINT OF STRAIGHT MOBILITY OF WHEELCHAIRS

Abstract

The purpose of this paper is to present a relative evaluation method of slipperiness of flat and inclined floors and pavements from a viewpoint of straight mobility of wheelchairs. First, scales of the mobility were made by sensory test in which a wheelchair was used to run on various samples. Then, slip-resistance values of samples were measured respectively with an apparatus developed by authors in former research, an evaluation index was proposed to correspond to scales. Consequently, the relative evaluation method of slipperiness of flat and inclined floors and pavements from the viewpoint of straight mobility of wheelchairs was presented.
