COORDINATED DATA SYSTEM FOR HIGHWAY PLANNING

COMPUTERS HAVE NOT BEEN USED EFFECTIVELY TO PROCESS HIGHWAY PLANNING DATA ALTHOUGH COMPUTER EQUIPMENT HAS BEEN AVAILABLE TO HIGHWAY PLANNING DIVISIONS FOR YEARS. A REVIEW OF COMPUTER APPLICATIONS FOR HIGHWAY PLANNING IN 45 STATE HIGHWAY DEPARTMENTS REVEALED TWO MAJOR REASONS THAT POSSIBLY EXPLAIN THIS. FIRST, MANUAL OPERATIONS HAVE BEEN CONVERTED DIRECTLY INTO COMPUTERIZED OPERATIONS WITH LITTLE IMPROVEMENT IN THE PROCESS BECAUSE BOTH PLANNING DIVISIONS AND DATA PROCESSING DIVISIONS HAVE GIVEN INSUFFICIENT TIME TO STUDYING THE ACTUAL PROCESSING REQUIREMENTS THROUGHOUT THE PLANNING DIVISIONS. SECONDLY, THERE IS A GENERAL LACK OF KNOWLEDGE BY PLANNING PEOPLE ABOUT THE CAPABILITIES FOR LATE MODEL COMPUTERS. THE PAPER DESCRIBES A SYSTEM THAT CAN LEAD TO AN EFFECTIVE USE OF COMPUTERS IN HIGHWAY PLANNING. IN THE SYSTEM, CALLED A "COORDINATED DATA SYSTEM," THERE IS A SEPARATE DATA FILE FOR EACH OF THE VARIOUS CLASSES OF PLANNING DATA. MOST OF THESE DATA ARE RELATED TO THE ROADWAYS THROUGH A LOCATION REFERENCE SYSTEM. THE ROADWAYS ARE CONSIDERED TO BE A COMMON REFERENCE BASE TO WHICH THE RELATION OF DATA IS THE BASIS FOR CORRELATING THE DIFFERENT FILES. THE SYSTEM PROVIDES FOR LOCATIONS OF DATA VALUES TO BE RECORDED AND STORED AS THE VALUES ARE OBSERVED TO OCCUR ALONG ROADWAYS RATHER THAN AS A COMPROMISE OF SEVERAL DIFFERENT USERS' REQUIREMENTS. IT ALSO PROVIDES FOR RETRIEVAL AND PROCESSING OF DATA FROM ANY NUMBER OF FILES IN THE WAY NEEDED BY A USER AND FOR MODULAR DEVELOPMENT OF THE DATA FILES. /AUTHOR/
