PASSING PERFORMANCE WITH IN-CAR DISPLAYS

PASSING AID SYSTEM II (PAS II), A TRAFFIC MONITORING SYSTEM CURRENTLY UNDER DEVELOPMENT, IS DESIGNED TO ADVISE DRIVERS ON 2-LANE ROADS WHETHER IT IS SAFE TO PASS IN A SIGHT-LIMITED SITUATION. THE PRESENT STUDY COMPARES THE EFFECTS OF ALTERNATE PASS II IN CAR DISPLAYS ON DRIVER PERFORMANCE IN A HIGHWAY DRIVING SIMULATOR. THE 3 DISPLAYS TESTED WERE AN ALPHAMERIC READOUT, A FLASHING-COLOR INDICATOR, AND AN AUDITORY SIGNALING SYSTEM; ALL 3 DISPLAYS INDICATED THE TIME BEFORE AN ONCOMING CAR WOULD BE MET. THE APLHAMERIC DISPLAY WAS RELATED TO CONSISTENT AND CONSERVATIVE PASSING UNDER NORMAL CIRCUMSTANCES. DRIVERS DID NOT RESPOND TO EMERGENCY SITUATIONS AS WELL WITH THE ALPHAMERIC AS WITH THE FLASHING DISPLAY. THE AUDITORY DISPLAY, WITH A REPETITIVE RATE OF SOUND, WAS CONFUSING TO DRIVERS. DRIVERS PREFERRED THE ALPHAMERIC DISPLAY AND RATED THE AUDITORY LOW. BASED ON BOTH THROUGHPUT AND SAFETY MAXIMIZATION, THE FLASHING DISPLAY WAS RECOMMENDED. /AUTHOR/
