METHODOLOGY FOR ESTABLISHING FRICTIONAL REQUIREMENTS

The nature of the wet-pavement skidding accident problem is briefly discussed. A cursory review of the traffic accident literature is given to highlight the roadway geometric and driver maneuver performance specific nature of the problem. A conceptual methodology to establish cost-effective frictional requirements is presented. This methodology is based upon the calculation of a margin of safety (MOS) defined as the difference between available tire-pavement friction and the level of driver demand for friction. Models to calculate the level of available tire-pavement friction and the level of frictional demand as a function of site specific traffic operational characteristics, roadway geometry, and surface characteristics are discussed, and an example is given for the case of two-lane passing. /Author/
