Traffic data acquisition from serial photographs by photographie image processing.

This report is based on the early work of Mr. L.M. Sista in traffic data acquisition, using image processing techniques. The author is also indebted to Messers. A.L. Fenaroli, F.A. Richell, and R.E. Ross, who continued Mr. Sista's research, and to others in traffic engineering who encouraged the effort. Valuable consultations and photographs were provided by the New York Port of Authority. A major portion of this work was performed for the Massachusetts Department of Public Works in cooperation with the United States Department of Commerce, Bureau of Public Roads.
