Florida Department of Transportation (FDOT) recently developed and implemented a new hydroplaning prediction (HP) program for predicting the traveling speed at which a vehicle would start hydroplaning. The tool was developed as part of the effort to reduce hydroplaning accidents and is being used during the roadway design phase to evaluate the hydroplaning potential of Florida’s roadways. This paper presents an overview of FDOT’s HP program and demonstrates how it may be used. The tool incorporates a total of four water film thickness models and three hydroplaning speed models developed in the past, allowing for a total of 12 model combinations for the hydroplaning analysis. The tool also offers different analysis options that may be used to meet a variety of FDOT’s needs. As demonstrated in this paper, the primary use of the new HP tool is for checking the final geometric roadway design parameters for hydroplaning potential. In addition, the HP program can also be used as a forensic investigation tool for identifying specific locations that exhibit higher potential for hydroplaning.

佛罗里达运输部（FDOT）最近开发并实施了新的滑水预测（HP）程序，用于预测车辆开始滑水的行驶速度。该工具是为减少滑水事故而努力开发的一部分，并在道路设计阶段用于评估佛罗里达州道路滑水潜力。本文概述了FDOT的HP程序，并演示了如何使用它。该工具总共包含了四个水膜厚度模型和三个过去开发的滑水速度模型，总共可以对滑水分析进行12种模型组合。该工具还提供了可用于满足FDOT各种需求的不同分析选项。如本文所示，新HP工具的主要用途是检查用于滑水潜力的最终几何巷道设计参数。此外，HP程序还可以用作法医调查工具，以识别具有较高滑水潜力的特定位置。
