Perceived slipperiness rating (PSR) has been widely used to assess walkway
safety. In this experiment, 29 participants were exposed to 5 floor types under
dry, wet and glycerol conditions. The relationship between their PSR and
objective measurements, including utilized coefficient of friction (UCOF), gait
kinematics and available coefficient of friction (ACOF), was explored with a
regression analysis using step-wise backward elimination. The results showed that
UCOF and ACOF, as well as their difference, were the major predictors of the PSR
under wet and glycerol conditions. Under wet conditions, the participants
appeared to rely on the potential for foot slip to form their PSR. Under glycerol
conditions, some kinematic variables also became major predictors of PSR. The
results show how different proprioceptive responses and ACOF contributed to the
prediction of PSR under different surface conditions.
