The research was conducted on the FHWA highway driving simulator (HYSIM) using 60 test subjects to examine driver responses to active advanced warning systems (AAWS) 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 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.
