Solar Powered Illuminated RPMs

Status: Complete

Description: The RPMs were easily installed and relatively low maintenance. The data showed no observable change in lane distributions that could be attributed to the greater visibility of the taper after installation of the RPMs. Subjective evaluation and review of driver’s view video footage suggested that the light emitted from the units was not sufficient to effectively improve taper delineation.
