IN THE FALL OF 1960 AND SPRING OF 1961 THE LOS ANGELES AREA DISTRICT AND THE SAN FRANCISCO AREA DISTRICT OF THE CALIFORNIA DIVISION OF HIGHWAYS WERE SUPPLIED WITH AN AERIAL PHOTOGRAPHIC INVENTORY AT A SCALE OF 200 FT TO 1 IN. OF MOST OF THE EXISTING FREEWAYS IN THOSE AREAS. THIS INITIAL INVENTORY ON 348 MILES OF FREEWAYS THEN EXISTING IN THESE TWO AREAS WAS OF AN EXPERIMENTAL NATURE TO DETERMINE WHETHER LARGE-SCALE AERIAL PHOTOGRAPHY WOULD BE USEFUL FOR TRAFFIC ENGINEERING APPLICATIONS SUCH AS STUDYING ACCIDENT PRONE LOCATIONS, DETERMINING VEHICLE MOVEMENT PATHS, AND IDENTIFYING SIGNING PROBLEMS. /AUTHOR/
