REPORT ON PENNSYLVANIA'S AUTOMATED ACCIDENT ANALYSIS SYSTEM

THE SYSTEM, BEGUN IN 1966, IS BASED ON STATE AND MUNICIPAL POLICE REPORTS, AND DRIVERS' REPORTS OF VEHICLE ACCIDENTS. DATA ON LOCATION IS CODED, EDITED, AND FILED IN A COMPUTER. USING ADDITIONAL DATA ON HIGHWAY ROUTE LENGTH, CLASSIFICATION, ADT, SURFACE WIDTH AND TYPE THE SYSTEM GENERATES SEVERAL TYPES OF REPORTS. THE THREE MOST WIDELY USED OF THESE REPORTS ARE THE 'CLUSTER' REPORT OF HIGHWAY ACCIDENT LOCATIONS, THE 'IMPROBABLE RATE' ACCIDENT LOCATION REPORT, AND COLLISION DIAGRAMS FOR AN INTERSECTION.
