The U.S. Department of Transportation Volpe National Transportation Systems Center conducted a study of the effectiveness of LED-enhanced R8-8 signs in reducing incidents of vehicles stopping on the tracks. The researchers captured video at the Brighton Street crossing in Belmont, MA before and after LED-enhanced signs were installed. The signs were standard R8-8 panels that read “DO NOT STOP ON TRACKS,” except that they had flashing white LEDs. Signs manufactured by two different companies were tested. Results showed the signs produced a 41 percent reduction in frequency of vehicles stopping on the tracks.
