| Pavement-tire friction provides the grip that is required for maintaining vehicle control and for Shopping in emergency situations. Statistically significant negative correlations of skid resistance values and wetpavement accident rates have been found in previous research. Skid resistance measured with SCRIM and crash data fromover 1750km of two-lane rural roads in the Spanish National Road Systemwere analyzed to determine the influence of pavement conditions on safety and to assess the effects of improving pavement friction on safety. Both wet- and dry-pavement crash rates presented a decreasing trend as skid resistance values increased. Thresholds in SCRIM coefficient values associated with significant decreases in wet-pavement crash rates were determined. Pavement friction improvement schemes were found to yield significant reductions in wet-pavement crash rates averaging 68%. The results confirm the importante of maintaining adequate levels of pavement friction to safeguard traffic safety aswell as the potencial of pavement friction improvement schemes to achieve significant crash reductions. | |
