Report: Minimum Retroreflectivity Levels for Blue and Brown Traffic Signs
In 2003, FHWA published research recommendations for minimum maintained retroreflectivity (MR) levels for traffic signs. The recommendations included most sign types but not white-on-blue signs or white-on-brown signs. In addition, the 2003 recommendations maintained that retroreflectivity levels were based on conditions representing dark rural environments. This report describes the research activities and consequent findings related to the development of recommendations for MR levels for white-on-blue signs and white-on-brown signs. This report also includes an investigation related to MR levels needed for complex visual conditions that include glare from oncoming headlamps and fixed roadway lighting.
