CHICAGO ACCIDENT REPORTING SYSTEM. PART 1: SYSTEM DESCRIPTION

THE CHICAGO ACCIDENT REPORTING SYSTEM IS A COMPUTERIZED INFORMATION STORAGE AND RETRIEVAL SYSTEM FOR USE BY THE BUREAU OF STREET TRAFFIC. ITS GOAL IS TO PROVIDE TIMELY DATA USEFUL TO THE BUREAU STAFF IN THE REDUCTION OF VEHICULAR ACCIDENTS IN ITS JURISDICTION. THE SYSTEM'S DATA BASE INCLUDES TEN FILES, WHICH STORE AND LOGICALLY INTERRELATE APPROXIMATELY A HALF MILLION RECORDS DESCRIBING VIRTUALLY EVERY MOTR VEHICLE ACCIDENT OCCURRING IN CHICAGO IN THE LAST FOUR YEARS. BESIDES THE CONSTRUCTION AND MAINTENANCE OF ITS FILES, THE SYSTEM'S CAPABILITIES INCLUDE PROVIDING SUMMARIES AND REPORTS, YIELDING ACCIDENT INFORMATION RELATED TO A VARIETY OF SPATIAL, TEMPORAL AND ACCIDENT CHARACTERISTICS, AS WELL AS DETAILED DATA DISCLOSURE. THE SYSTEM ALSO HAS THE MECHANISM FOR SEEKING OUT THOSE LOCATIONS IN CHICAGO WHOSE ACCIDENT HISTORY IS SUFFICIENTLY ALARMING TO MERIT IMMEDIATE EXAMINATION AT THE DETAIL LEVEL. AS DELIVERED, THE SYSTEM COMPRISES EIGHT PROGRAM MODULES WRITTEN FOR THE IBM SYSTEM 1360 COMPUTER. FOR EASE OF MAINTENANCE AND PORTABILITY, MOST OF THE CODE IS COBOL. PROGRAM CONSTRUCTION AND FILE FORMATS ARE DESIGNED TO FACILITATE THE ADDITION OF FUTURE MODULES AS NEW REPORTING OR ANALYTICAL CAPABILITIES BECOME DESIRABLE. /AUTHOR/
