RESULTS FROM THE TESTING OF ELEVEN COLLISION AVOIDANCE SYSTEMS (CAS) FOR LANE CHANGE, MERGE AND BACKING ARE PRESENTED. COMPLETE SYSTEMS WERE TESTED FOR STATIC PATTERN, LATENCY TIME AND DYNAMIC RESPONSE TO POTENTIAL TARGETS. TESTING WAS PERFORMED STATICALLY, IN A CONTROLLED TEST TRACK ENVIRONMENT AND ON PUBLIC ROADS TO OBTAIN OPERATIONAL AND PERFORMANCE DATA. SENSOR SYSTEMS WERE MOUNTED ON A TEST VEHICLE EQUIPPED WITH A SELF-CONTAINED DATA ACQUISITION SYSTEM AS WELL AS CALIBRATED VIDEO CAMERAS FOR GROUND TRUTH. THERE WAS OBSERVED TO BE A WIDE SCATTER IN THE PERFORMANCE CAPABILITY OF THE VARIOUS SENSOR SYSTEMS. RESULTS FROM THE LANE CHANGE/MERGE SENSOR SYSTEMS INDICATED THAT THE MEASURE OF THE TRUE NEGATIVE (TN) RESPONSE OF THE SYSTEM COULD BE A USEFUL METRIC TO JUDGE THE RELATIVE EFFECTIVENESS OF THE SYSTEM TESTED. MOST OF THE SYSTEMS IN THIS CATEGORY WERE SIMPLE PROXIMITY DETECTORS, WHILE THOSE THAT CLAIMED TO DISCRIMINATE AGAINST NON-MOVING GROUND OBJECTS DID SO WITH ONLY FAIR RESULTS. TWO OF THE FOUR BACKING SYSTEMS PROVIDED WARNINGS TO THE DRIVER AND WERE BASED ON ULTRASONIC TECHNOLOGY. THEY PROVED TO BE EXTREMELY SENSITIVE AND PRONE TO FALSE ALARMS. VIDEO SYSTEMS FOR BACKING APPEAR TO BE QUITE CAPABLE OF EXTENDING THE DRIVER'S FIELD OF REGARD. ONE APPEARED TO BE OF LIMITED UTILITY AT NIGHT.
