In recent decades, injury has begun to gain prominence as a public health and societal problem. Slipperiness and slip, trip, and fall (STF) injuries are among the greatest obstacles to reducing the injury burden. One of the biggest challenges in STF is defining and measuring slipperiness. After over half a century of serious research on what slipperiness is and how it can be measured, rapid progress has been made in the decade of the 90s. Measuring Slipperiness: Human Locomotion and Surface Factors provides an overview of basic concepts and definitions of terms related to the 'measurement of slipperiness' from the onset of a foot slide to a gradual loss of balance and a fall. The book includes expert group perspectives on human-centered (biomechanical, locomotive, perceptual, and cognitive), and surface-centered (roughness, friction) aspects and approaches. It addresses the injury burden of slipperiness, globally reviews existing slipmeters, and summarizes areas of consensus in the field of slipperiness measurement. Perhaps the most comprehensive treatment of the subject ever compiled, the book contains contributions from North America, Europe, Asia, and Oceania including the National Laboratories of Finland, France, the U.K., and the U.S. A valuable, state-of-the-art textbook, it provides students with a useful starting point for understanding the many aspects of STF.

This book examines pedestrian shoe-floor slip resistance from an engineering standpoint in order to better understand friction and wear behavior. This analysis includes an extensive investigation into the surface properties of shoes and flow, and the measurement of dynamic friction and other mechanical and physical aspects of shoe-floor tribology. Lastly, the book proposes a measurement concept for the identification and classification of operational floor surfaces under a range of different conditions. Novel techniques and methods are proposed that can improve the reliability of slip resistance assessments. The current state of knowledge is critically examined and discussed from a tribological perspective, including aspects like friction, wear, lubrication and the mechanical behavior of shoes, floors and their wider environment. Further, the book reports on extensive experimental investigations into the topographical characteristics of shoe and floor surfaces and how they affect slip resistance. Slips resulting in pedestrian falls are a major cause of injuries and deaths for all age groups. This important book provides essential insights for researchers, practicing engineers and public safety officials wishing to learn about how the risk of pedestrian slips can be assessed and understood.
