THE CONTINGENCY CHECK PROGRAM

BEFORE THE GREAT WEALTH OF INFORMATION DERIVED FROM THE FIVE ORIGIN AND DESTINATION SURVEYS CONDUCTED BY THE SEWRPC AND TRANSCRIBED TO PUNCHED CARDS COULD BE USED IN PLANNING ANALYSES AND IN PLAN PREPARATION, IT IS IMPERATIVE THAT EVERY EFFORT BE MADE TO ASSURE THE ACCURACY AND RELIABILITY OF THE DATA AS RECORDED IN THE PUNCHED CARDS. A COMPREHENSIVE CONTINGENCY CHECK PROGRAM WAS DEVELOPED TO VERIFY THE ACCURACY AND COMPLETENESS OF THE DATA IN THE SURVEY CARDS. THIS PROGRAM IS DESCRIBED AND INCLUDED IS AN EXPLANATION OF THE BASIC CONTINGENCY CHECKS, A DESCRIPTION OF THE OPERATIONAL PROCEDURES, THE TYPE OF ERRORS FOUND BY EACH CHECK, AN EVALUATION OF THESE ERRORS, RECOMMENDATIONS TO ASSIST IN REDUCING THE NUMBER OF ERRORS IN FUTURE SURVEYS, AND THE COSTS OF CONDUCTING THE SEWRPC CONTINGENCY CHECK PROGRAM. THE 23 CONTINGENCY CHECKS APPLIED VERIFIED THE CODING ACCURACY OF ABOUT 4.6 MILLION ITEMS /FIELDS/ AND CHECKED THE LOGIC OF ABOUT 3.9 MILLION DIFFERENT RELATIONSHIPS BETWEEN ITEMS /FIELDS/ IN THE APPROXIMATELY 410,000 O & D SURVEY CARDS.
