The role of tire to road coefficient of friction is of major importance in accident reconstruction. Dependency of friction on relative sliding speed between tire and road surface, as well as on tire and pavement properties, must be taken into account for accurate analysis of both pre- and post-impact vehicle motion. In this paper, characteristics of energy dissipation between tire and pavement during locked-wheel sliding are discussed. Several test methods for measuring tire/pavement coefficient of friction are briefly compared. This paper then discusses an experimental procedure utilizing a test vehicle with an onboard microcomputer-based data acquisition system and instrumentation package. The signal conditioning, filtering and analysis techniques employed in this work are then presented. Results of skid tests performed at various speeds are also presented. Finally, predictability of high speed coefficient of friction curves from low speed skid tests is presented.
