Chapter 3 - Recommended MUTCD Language
| < Previous | Table of Content | Next > |
This chapter describes the specific recommendations originating from the workshops for the FHWA to consider in developing the proposed rule for the Federal Register. These recommendations reflect the general opinions of the majority of the workshop participants as interpreted by the report authors. Given the range of opinions regarding minimum retroreflectivity levels for pavement markings, the participants worked together to develop recommendations for the FHWA to consider. Suggested MUTCD wording from each workshop is shown in Appendices C and D.
MUTCD Language
- A phase-in time is needed to allow agencies time to study/customize the most appropriate method to manage pavement marking retroreflectivity in their jurisdiction. This should include a time for the study of the method, and then additional time to gear up, which might require reprioritizing as well as presentations and reports to budget personnel (e.g., city council) for the funds needed to purchase equipment, survey current conditions, attain management services, etc.
- The MUTCD language should include a Standard statement requiring a method to maintain pavement marking retroreflectivity in accordance with a table to be published in the MUTCD. The requirements in this Standard statement should only apply to markings that are required by the MUTCD. The Standard statement should also require that pavement markings with retroreflectivity levels below the minimum shall be scheduled for replacement when conditions permit.
- An Option statement should be included that exempts symbols, arrows, and words, unless otherwise required by the MUTCD.
- An unambiguous measurement protocol is needed to compare marking retroreflectivity to the minimum levels developed by the FHWA.
Table of Minimum Retroreflectivity Levels
- Include classifications based on speed of the roadway.
- Provide a discount for RRPMs and lighting, but include unambiguous information concerning the working condition of RRPMs and lighting.
- Include classifications based on color of the marking.
Maintenance Methods
- List maintenance methods that the FHWA considers acceptable.
- Allow flexibility for agencies to customize their own method based on their specific needs in their jurisdiction.
- Provide a supplemental document that includes additional information.
