THE GCARS SYSTEM FORTRAN IV PROGRAMMERS MANUAL - PART A - PROGRAMS FOR DATA COLLECTION AND EVALUATION

THE GENERALIZED COMPUTER-AIDED ROUTE SELECTION (GCARS) SYSTEM WAS DEVELOPED TO ASSIST ENGINEERS IN DEFINING OPTIMAL HIGHWAY ALTERNATIVES IN TERMS OF CONFLICTING HIGHWAY LOCATION FACTORS. THE FACTORS CONSIDERED PERTINENT TO THE ANALYSIS ARE REDUCED TO NUMERICAL MODELS. SAMPLING OF AREAL DATA PROVIDES THE DATA TO BE REDUCED TO THE NUMERICAL MODELS. THE SUBSEQUENT COMPUTER ANALYSIS DEPENDS ON THE QUALITY OF THE INFORMATION COLLECTED. THIS PROGRAMMERS MANUAL DESCRIBES THE COMPUTER ROUTINES DEVELOPED TO: (1) ASSIST IN THE DESIGN OF SAMPLING PROCEDURES FOR TOPOGRAPHIC DATA (PROGRAM VECTOR), (2) CONVERT CARD DATA TO STANDARD GCARS SYSTEM TAPES (PROGRAMS LOADS AND LOADG), AND (3) TEST SAMPLED DATA FOR ACCURACY AND LACK OF BIAS (PROGRAMS TREND AND RESMAP). THE DIGITAL COORDINATOGRAPH USED TO DIGITIZE THE MAP DATA IS PICTURED. THE MACHINE PUNCHES THE DATA ONTO CARDS THROUGH AN ATTACHED CARD PUNCH. PROGRAM LOADS ALLOWS THE CONVERSION OF LARGE UNWIELDY CARD DATA DECKS TO MORE CONVENIENT TAPES. PROGRAM LOADG PERFORMS SIMILAR FUNCTIONS FOR GIRDDED DATA ARRAYS PRODUCED LATER. THE REMAINING PROGRAMS PERFORM VARIOUS STATISTICAL AND DISPLAY FUNCTIONS DESIGNED TO ASSIST IN DATA EVALUATION.
