OFFICE OF SAFETY Proven Safety Countermeasures Backplates with Retroreflective Borders Backplates added to a traffic signal head improve the visibility of the illuminated face of the signal by introducing a controlled-contrast background. The improved visibility of a signal head with a backplate is made even more conspicuous by framing it with a 1- to 3-inch yellow retroreflective border. Signal heads that have backplates equipped with retroreflective borders are more visible and conspicuous in both daytime and nighttime conditions. This treatment is recognized as a safety countermeasure is to adopt human factors enhancement of it as a standard treatment for Safety Benefits: traffic signal visibility, conspicuity, signalized intersections across a 15% and orientation for both older jurisdiction or State. and color vision deficient drivers. Implementation challenges This countermeasure is also include minimizing installation time, reduction in total crashes.1 advantageous during periods of accessing existing signal heads, and power outages when the signals structural limitations due to added would otherwise be dark, providing a wind load in instances where an visible cue for motorists to stop at the entire backplate is added.

Retroreflective Border Retroreflective borders are highly visible during the night. Source: South Carolina DOT Considerations Transportation agencies should consider backplates with retroreflective borders as part of their efforts to systematically improve safety performance at signalized intersections. Adding a retroreflective border to an existing signal backplate is a very low-cost safety treatment. This can be done For more information on this by either adding retroreflective and other FHWA Proven Safety tape to an existing backplate or Signal Backplate Countermeasures, please visit purchasing a new backplate with https://highways.dot.gov/ a retroreflective border already Signal backplate framed with a retroreflective border.
