Interstate Wet Pavement Hot-Spots
Wet Pavement Hot-spots are determined to help law enforcement officers know where crashes are more likely to occur during and shortly after wet weather. This will enable them to prevent crashes by law enforcement presence, which tends to slow the traffic and make the drivers more attentive. It will also be useful to positions law enforcement as first responders to areas during heavy or extended rainfall that have had a history of more than expected wet pavement crashes.
This document is in three parts:
- A preliminary mile-posted analysis that walks the reader through the methods used in determining the wet pavement hot-spots,
- The hot-spot analysis itself, and
- A CARE IMPACT analysis to provide insight into how collectively the wet pavement hot-spot subset compares to Interstate crashes in general.
It is expected that this third section will be useful in training law enforcement and engineers on what to look for to remediate the problems of high wet pavement crash areas.
