Abstract : A two-week sample of the statistical data now being accumulated from the San Francisco Harbor Advisory Radar system was examined and analyzed. Errors and limitations of the existing data and data reduction processes are determined and analysis procedures are explored. The existing data and data reduction processes are determined and analysis procedures are explored. The existing data base consists of computer cards, unit logs, and films from the radar. The principal results of the analysis indicate that detailed origin-destination information is readily available while ship tracks and analysis of traffic conflicts is expensive to obtain. An analysis of data errors was made and techniques were developed to profile vessel speeds and miss distances. (Modified author abstract)
