Retroreflectivity Defined


  “A property of a surface that allows a large
portion of the light coming from a point source
to be returned directly back to a point near its
                     origin.”


     Source: MUTCD, 2009 Edition, Section 1A.13 Definitions of
             Headings, Words, and Phrases in this Manual
Minimum Retroreflectivity

Standard (i.e. mandatory practice):
“Public agencies or officials having jurisdiction shall
 use an assessment or management method that is
designed to maintain sign retroreflectivity at or above
         the minimum levels in Table 2A-3.”

             Minimum Retroreflectivity
Minimum Retroreflectivity

Assessment and Management Methods
     to maintain minimum levels
    A. Visual Nighttime Inspection
    B. Measured Sign Retroreflectivity
    C. Expected Sign Life
    D. Blanket Replacement
    E. Control Signs
    F. Other Methods

   Eliminate other milestones
     Source: Federal Register, August 31, 2011
Minimum Retroreflectivity

        What does this mean?
   Jurisdictions are expected to upgrade signs over
    time to meet new requirements utilizing a systematic
    upgrading program
   Agencies can prioritize and schedule based on
    relative safety needs, resources, etc
   Agencies can decide to wait until non-compliant
    signs reach serviceable life and replace with
    compliant signs
Meeting MUTCD Requirements

          Twofold Requirement
    Systematic approach to maintain minimum
     retroreflectivity
    Compliance with other standards in both the
     National MUTCD and NYS Supplement
