TRAFFIC DATA COLLECTION AND ANALYSIS BY PHOTOGRAMMETRIC METHOD

REPEATED STRIP AERIAL PHOTOGRAPHY WAS EMPLOYED TO OBTAIN TRAFFIC DATA WHICH WERE SUBSEQUENTLY ANALYZED IN THE TRADITIONAL FORM. A PHOTOGRAMMETRIC PARKING STUDY WAS CONDUCTED OF AN 80-SPACE CAR PARK. FROM THE SAME PHOTOGRAPHS A SPEED STUDY WAS UNDERTAKEN OF AN AREA OF APPROXIMATELY 0.5 SQ. KM, COMPRISING NEARLY 5 KM OF ROADS, WITH A 50KM/H SPEED LIMIT. A SAMPLE SIZE OF 161 PHOTOGRAMMETRIC VEHICLE-SPEED RECORDS PROVIDED A SPEED MEASUREMENT ACCURACY OF PLUS OR MINUS 0.9 KM/H FOR THE MEAN TRAVELLING SPEED OF 30 KM/H. THE SIMPLICITY OF OPERATION AND ECONOMY COMPARED WITH TRADITIONAL METHODS STRONGLY SUPPORTED THE IMPLEMENTATION OF PHOTOGRAMMETRY FOR TRAFFIC AND LAND USE/TRANSPORTATION STUDIES. /TRRL/
