PRESENTATION OF EVALUATION INDEX AND EVALUATION METHOD OF SLIPPERINESS OF FLOORS AND PAVEMENTS FROM A VIEWPOINT OF SAFETY ON RIDING A BICYCLE : Study on a relative evaluation method of floors and pavements from a viewpoint of slipperiness on riding a bicycle (Part 3)

Abstract

This paper presents a method to evaluate the slipperiness of fioors and pavements from a VieWpoint of safety on riding a bicycle ， which is based on the relation between the evaluating scales of slipperiness and Slipperiness ． index (C． S． R − BIKE)， measured with developed Slip meter reported in part2 ． The outl e of this study is as follows． The first ， the evaluating scales of safety of SlipPeriness Were made by sensory test by means of 且oors and bicycle ． Then ， the C ． S． R − BIKE of floors was m6asured with the developed slip meter ， Based on the relation between the evaluating scales and the C ， S， R − BIKE， evaluat 童 oll index and evaluation method of Slipperiness of floors and pavements from a VieWpoint of safety on dd g bieycle was presented ． Keywords ' Bicycfe， Siip ρetiness of fioors a η ゴ P ∂ μθ叨 θη 齲 Safety ． Evaluation method ． Evaluation index
