The following retroreflectivity resolution was passed by the AASHTO Board of Directors at its Annual Meeting in December 2000.
AASHTO POLICY RESOLUTION
MINIMUM LEVELS OF RETROREFLECTIVITY FOR SIGNS AND PAVEMENT MARKINGS
Passed at the AASHTO Annual Meeting, December 2000
WHEREAS, the American Association of State Highway and Transportation Officials (AASHTO) is aware of the congressional mandate for the Secretary of Transportation to revise the Manual on Uniform Traffic Control Devices to include a standard for the minimum level of retroreflectivity that must be maintained for pavement markings and signs, which shall apply to all roads open to public travel, and
WHEREAS, AASHTO concurs that it is desirable to maintain an adequate level of retroreflectivity for both traffic signs and pavement markings to enhance safety for motorists during hours of darkness and during adverse weather conditions, and
WHEREAS, AASHTO is concerned about additional liability for transportation agencies if the Federal Highway Administration (FHWA) establishes the proposed minimum levels of retroreflectivity, and
WHEREAS, AASHTO greatly appreciates the opportunity afforded by FHWA to consider recommendations from AASHTO prior to publishing proposed rulemaking for minimum retroreflectivity for both signs and pavement markings;
THEREFORE, AASHTO established a "Task Force on Retroreflectivity Guidelines" composed of members from federal, state, and local transportation agencies, and from several transportation and industry associations, and has studied the various issues and produced a report with recommendations; and
THEREFORE, BE IT RESOLVED that based upon the findings and recommendations of the Task Force, AASHTO agrees that:
BE IT FURTHER RESOLVED, that efforts to assure adequate night visibility should not impose undue burdens on highway agencies, and to that end, AASHTO recommends that FHWA consider the following:
FURTHER, it should be noted that the AASHTO Task Force on Retroreflectivity Guides will evaluate forthcoming FHWA findings and recommendations relative to minimum retroreflectivity values for additional types of signs and for pavement markings as they become available, and will provide comments at that time.
FHWA editorial note:
The four methods in No. 4 in the resolution are for evaluation processes and are briefly described as follows:
