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.
自 20 世纪 50 年代末发现水滑现象以来，它一直是湿滑路面上驾驶员关注的问题，因为它会影响驾驶员的安全。事实上，这种现象会导致轮胎和路面之间形成的水层完全切断轮胎与路面之间的接触，从而导致纵向和横向抓地力完全丧失。尽管水滑现象已经存在了大约 60 年，但几乎不可能找到任何关于水滑现象会导致车辆事故的频率的科学估计，尤其是在欧洲。为了弥补这一空白，著名的德国深入事故研究（GIDAS）项目协助进行了一项研究。得益于 GIDAS，人们得以在湿滑路面上识别出足够数量的案例，这些案例具有相关参数的高度准确性信息。通过对所有案例进行物理分析，可以计算出事故案例处于完全水滑状态的概率。这使得对事故发生时完全水滑状态的实际重要性进行精确估计成为可能，这表明完全水滑状态是一种比大多数驾驶员想象的更为罕见的事故原因。
