Work Zone Mobility and Safety Program

Conclusion

The results of the 2010 WZ SA show continued progress Nationally toward implementation of the work zone best practices identified in the WZ SA. The 2010 WZ SA National average score of 10.0 represents a 3 percent increase over the 2009 National average. This increase was experienced across the country and is based on increases in 41 agencies (80 percent). This increase continues a steady trend over the eight years the WZ SA has been conducted.

The practices asked about in the WZ SA questions are consistent with the work zone management principles promoted by the Rule. This is particularly evident as this is the third WZ SA since the compliance date for the Rule. Additionally, FHWA continues to promote sound work zone management practices that can lead to reduced congestion and delay while improving safety in and around work zones. FHWA is particularly active in promoting practices through training, workshops, guideline development, and other research studies.

In addition to the quantitative results, this report shares specific examples cited by various agencies in written comments they submitted to support their numeric ratings. FHWA encourages agencies to consider implementing some of these good practices from other agencies to enhance their own practices. As a means of sharing these good examples further, FHWA will also review these examples for possible inclusion in future outreach and guidance documents.
