Expert system to calculate the coefficient of friction - an approach to enhance traffic safety

Abstract

Ahsiract -Friction plays a key role in causing slipperiness as a low coefficient o f friction on the road may result in slippery and hazardous conditions. Analyzing the strong relation between friction and accident risk on winter roads is a difficult task. Many weather forecasting organizations use a variety of standard and bespoke methods to predict the cocfticient o f friction on roads. This article proposes an approach to predict the extent of slipperiness by building and testing an expert system, I t estimates the coefficient of friction on winter roads in the province of Dalarna, Sweden using the prevailing weather conditions as a basis. Weather data from the Road Weather Information System, Sweden (RWIS) was used. The focus o f the project was to use the expert system as a part of a major project in VITSA, within the domain of Ihtclligent Transport Systems.
