Determine Drainage Basin Mapping and Estimation of Hydroplaning
| 项目名称： | Determine Drainage Basin Mapping and Estimation of Hydroplaning |
| 摘要： | Research project 0-6896, Proper Selection of Ride Quality Pay Adjustment Schedule and Re-Evaluation, used mobile LiDAR to map surface features of the highway network. Many of these surface features included drainage related elements such as ditch depth, ditch slope, and paved surface area drainage mapping. During the project, a method was developed to use the mapped drainage basins to calculate water film thickness and subsequently estimate hydroplaning potential using formulas from literature. With drainage basin information, the Receiving Agency can identify roadway sections with geometry that could have poor wet weather performance. Using the surface measurements from mobile LiDAR, the Receiving Agency can home in on the exact location of the poor geometry and craft a solution that is more precise and specifically targets the geometric attributes that need to be improved. In addition, because mobile LiDAR can be collected at the network level, this provides the Receiving Agency the opportunity to be proactive and address poor geometric conditions that can lead to wet weather crashes, even if they do not currently exist. |
