A supplemental notice of proposed amendments (SNPA) addressing minimum retroreflectivity levels for pavement markings was published in the Federal Register on January 4, 2017 The SNPA modifies theApril 2010 proposal for minimum pavement marking retroreflectivity levels by offering a simplified set of standards.
At this time, there are no federally required minimum levels of retroreflectivity for pavement markings On April 22, 2010, a standard for maintaining minimum retroreflectivity of longitudinal pavement markings was published as a notice of proposed rulemaking in the federal register.
The actual service life of the pavement markings is of concern to both the NJDOT and FHWA Currently, there are no minimum pavement marking retroreflectivity requirements specified in the Manual on Uniform Traffic Control Devices (MUTCD) Consequently, the FHWA requested all the State.
Pavement markings are the primary roadway lane position guidance provided to motorists, and their function is particularly important during night-time driving conditions Maintaining minimum retroreflectivity to ensure roadways are safe to travel at night is the purpose for FHWA's proposed minimum retroreflectivity standards in the MUTCD.
