AERIAL PHOTOGRAPHIC INSTRUMENTATION SYSTEM FOR COLLECTION OF COMPLETE TRAFFIC FLOW CHARACTERISTICS DATA FOR STUDIES IN TRAFFIC FLOW AND HIGHWAY SAFETY

RESEARCHERS HAVE HAD TROUBLE OBTAINING DETAILED INFORMATION ON TRAFFIC FLOW CHARACTERISTICS, THEREFORE A SYSTEM OF INSTRUMENTATION HAS BEEN DEVELOPED FOR THE PRECISE MEASUREMENT OF TRAFFIC FLOW. THE SYSTEM EMPLOYS BOTH AERIAL AND GROUND PHOTOGRAPHIC TECHNIQUES. IT HAS BEEN USED TO STUDY THE EFFECTS OF EXIT RAMPS ON FREEWAY OPERATION AND CONTROL.
