Highlights The importance of full hydroplaning as a main cause of traffic accident is badly known in the scientific literature. German In-Depth Accident Study (GIDAS) enables to get relevant objective data from accidents. Associated to a physical analysis, an evaluation of the share of full hydroplaning as accident main cause was conducted. It appears that full hydroplaning accident exists, but they are much rarer than most driver think.
Abstract Since its discovery at the end of the 1950′s, hydroplaning has been a matter of concern for drivers on wet roads because it can affect driver safety. Indeed, this phenomenon can lead to a complete loss of contact between the tire and the road caused by the layer of water that develops between them, resulting in a complete loss of longitudinal and lateral grip. Although the phenomenon of hydroplaning is about 60 years old, it is almost impossible to find any scientific estimation of how frequently vehicle accidents can be caused by hydroplaning, especially in Europe. To cover this gap, the well-known German In-Depth Accident Study (GIDAS) project has assisted to conduct a study. Thanks to GIDAS, it was possible to identify a sufficient number of cases on wet roads including a high accuracy of information about relevant parameters. With a physical analysis of all the cases, it was possible to compute the probability for an accident case to be in a full hydroplaning situation. This allowed for a precise estimate of the real importance of full hydroplaning situations on accident occurrence, which appears to be a much rarer accident cause than most drivers think.
