Tire Wet-Pavement Traction Management for Safer Roads

The first part of this paper includes a summary of the most relevant studies on the relationship between accidents and indicators of tire-pavement traction. The results of this research are the basis for the design standards in various Countries in the world for the management of road surface and for defining threshold levels of skid resistance. The second part of this work proposes a review of levels of skid resistance for an existing road and introduces a relationship between the SFC (Sideway-Force Coefficient) parameter and road geometry (radius of curves, superelevation, design speed), and, consequently, with the demand of traction.
