Computational tools that can predict hydroplaning risk are invaluable to departments of transportation for drainage designs associated with new pavements or lane expansions. PAVDRN is a computer software package developed under NCHRP sponsorship to determine threshold hydroplaning speeds on a given section of a highway during adverse weather conditions. This study evaluated the reliability of the PAVDRN software in predicting dynamic hydroplaning by using past statistics on dynamic hydroplaning accidents in the state of Florida. Two approaches, based on (a) estimated travel speed and (b) posted speed, were used to assess PAVDRN%26apos;s effectiveness in accurately predicting hydroplaning accidents. Both approaches showed that this software had a reasonable degree of reliability. A third effort was also used to provide upgraded and realistic hydroplaning risk estimates when PAVDRN was used. This effort was facilitated by using additional information from the Florida Department of Transportation crash database to account for extraneous factors associated with hydroplaning that were not considered in PAVDRN%26apos;s analytical models.
