THE EFFECT OF PAVEMENT SKID RESISTANCE ON WET PAVEMENT ACCIDENTS IN INDIANA

This research investigates the relationship between accidents on wet surfaces and the skid resistance of those surfaces. The research also attempts to specify a minimum level of skid resistance acceptable for driving safety. A wet accident index was formulated and used as an indicator of the relative safety in comparing sections of highway when wet. A skidding ratio was also used. Data analysis for correlation between the wet accident index and average skid number was used on Interstate, four lane, and two lane road sections. The research concludes that there are several factors involved in specifying minimum skid number values and that there is no single value which applies to all road sections. The type of road, its volume, geometry and amount of access control should all be considered in determining minimum skid number standards.
