Effect of Step Length and Walking Speed on Traction Coefficient and Slip between Shoe Sole and Walkway

The effect of gait parameters such as step length and walking speed on the traction coefficient and the slip between a shoe sole and a walkway was clarified experimentally, and desirable gait to reduce the chance of slipping was also suggested. The maximum peak value of traction coefficient obtained...
