4.0 Summary - State Practices to Reduce Wet Weather Skidding Crashes

4.0 Summary

This section provides a comparison of the five state programs and general findings on the practices used for crash reduction programs focused on wet weather skidding crashes.

4.1 Identification of Wet Weather Crash Locations

All states reviewed conduct a statewide analysis on an annual basis and consider both concrete and asphalt pavements. Table 4.1 provides a summary of the procedures and factors used by each of the five states for identifying locations with wet weather crashes to investigate further.

2.0 Components of a Wet Weather Crash Reduction Program - State Practices to Reduce Wet Weather Skidding Crashes

2.0 Components of a Wet Weather Crash Reduction Program

The review of state wet weather crash reduction programs identified four common program components: identification of wet pavement crash locations, friction testing procedures, investigation and remedial action of wet pavement crash locations, and project and program evaluations. This section describes the importance of each component and related FHWA guidance.

1.0 Introduction and Background

This section provides an overview of the wet weather crash problem, the purpose of this guide, the research methodology used, and the organization of this guide.

Speed Management Workshops

A series of pilot workshops were held around the country to provide platforms for researchers, engineers, law enforcement, educators and policy makers to address speed-setting and enforcement issues. Building on the success of these workshops, the U.S. DOT has developed a Speed Management...

Engineering Speed Management Countermeasures

A Desktop Reference of Potential Effectiveness in Reducing Speed

July 2014

This chart summarizes studies about engineering countermeasures used to manage speeds. Studies where an increase in speed were reported are also shown since this information is also relevant in selection of countermeasures.

Speeding in Rural Areas

6. Selected Speed Management Case Studies

The following four case studies show different approaches towards addressing speed management within the community. Figure 5-1 notes the variety of approaches which include:

• Community initiative.
• Rural area evaluation.
• Strategic planning.
• Engineering study.

A brief summary is provided for each case study, followed by a hyperlink to a report or other document that provides additional detail.
