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 drivers view video footage suggested that the light emitted from the units was not sufficient to effectively improve taper delineation.
