Slipperiness

Slippery warning sign in New Taipei, Taiwan.

Slipperiness is the degree of risk of slippage or falling when walking on a wet surface such as a pathway, boat deck or roadway. Road slipperiness is a major area of road safety, but various means have also been developed to measure walkway and deck slipperiness in order to develop health and safety standards.[1] Energy loss over a measured distance of movement across a surface is called the "anti-slip" coefficient.[2][3]

Human subjects seem to be capable of differentiating the slipperiness of floors (Yoshioka et al. 1978, 1979, Swensen et al."

The design is based on the premise that, in the process of ordinary Walking, slipping is most likely to occur when the rear edge of the heel contacts the walkway surface. The value obtained by this machine, the energy loss in a measured distance of movement across the surface, is called the "anti-slip" coefficient."
