WHAT THIS IS ABOUT

The Federal Highway Administration revised its Manual on Uniform Traffic Control Devices (MUTCD) in 2008 to establish minimum retroreflectivity levels that must be maintained for traffic signs. These changes have required many state and local roadway agencies across the nation to significantly revise their approach to traffic sign materials, maintenance, and service life. This workshop will detail the 2008 changes to the MUTCD, discuss subsequent revisions to the MUTCD that affect traffic sign retroreflectivity standards and compliance dates, and identify real-world examples of sign retroreflectivity management and measurement techniques. The workshop will discuss several different sign assessment, measurement, and management techniques, including: nighttime inspection, calibration signs, measured sign retroreflectivity, expected sign life, blanket replacement, and control signs.

WHO SHOULD ATTEND?

This workshop will provide useful and important information for any transportation official responsible for the purchase, installation, or maintenance of traffic signs. Ideal participants include highway superintendents and public works directors, engineering consultants, maintenance foremen, and sign shop employees. This workshop may also be helpful for elected officials or administrators who oversee local street and highway budgets.
