Abstract:

This research was conducted on the FHWA highway driving simulator (HYSIM) using 60 test subjects to examine driver responses to active advanced warning systems (MWS) at high-speed signalized intersections. Measures of effectiveness included identification distance, reaction time, vehicle approach speed, and vehicle lateral placement measured on the HYSIM. Driver preferences were obtained from an interview following the driving test. The MWS's examined were "PREPARE TO STOP WHEN FLASHING" with flashing beacons using both a diamond-shape sign, and a rectangular sign mounted both on an overhead structure and ground-mounted on the roadside. Also a symbolic signal ahead sign with flashing lights and a "RED SIGNAL AHEAD" sign with the "RED" flashing, were candidate test signs. The standard "SIGNAL AHEAD" and the symbolic signal ahead signs were also displayed. The results indicated the symbolic signal ahead sign with flashing beacons had the greatest identification distance among all the test signs and was preferred by most drivers. No differences could be detected between ground-mounted versus overhead signs. All the active advance warning signs were superior to the standard passive warning signs.
