TRAFFIC FLOW INVESTIGATIONS BY PHOTOGRAMMETRIC TECHNIQUES

A METHOD DESIGNED TO MEASURE TRAFFIC MOVEMENT IN A MANNER WHICH IS APPROPRIATE FOR THE TESTING AND VALIDATION OF MOST OF THE PRESENT THEORIES OF TRAFFIC FLOW HAS BEEN DEVELOPED. DETERMINATION OF THE VEHICLE SPACING AND SPEEDS FOR A PLATOON OF VEHICLES AT RELATIVELY SHORT INTERVALS OF TIME IS OF PRIMARY IMPORTANCE. THE BASIC PROCEDURE CONSISTS OF PLACING A VEHICLE IN THE TRAFFIC STREAM AND FOLLOWING IT BY A HELICOPTER FROM WHICH PHOTOGRAPHS WERE TAKEN AT FIXED INTERVALS OF TIME. THE EQUIPMENT USED AND DATA REDUCTION TECHNIQUES ARE DESCRIBED AND SAMPLES OF RESULTANT DATA ARE SHOWN.
