A COMPUTER TECHNIQUE FOR PERSPECTIVE PLOTTING OF ROADWAYS

THE REPORT DESCRIBES THE DEVELOPMENT OF A COMPUTER PROCESS THAT WAS USED FOR PREPARING PERSPECTIVE VIEWS OF A ROADWAY. THE TECHNIQUE THAT WAS DEVELOPED WOULD CONCEIVABLY HAVE APPLICATION IN GENERAL ROADWAY DESIGN, INTERCHANGE DESIGN, AND THE LOCATION OF SIGNS AND OTHER TRAFFIC CONTROL DEVICES FOR GREATEST EFFECTIVENESS. THE NUMERICAL METHODS USED IN THE PLOTTING TECHNIQUE WERE DEVELOPED AND CHECKED ON THE IBM 7094 DIGITAL COMPUTER. THE PROGRAM PACKAGE WAS ORGANIZED AS A FORTRAN MAIN PROGRAM WHICH LINKS SEVERAL IBM 7094 SUBROUTINES TO PERFORM THE VARIOUS MANIPULATIONS REQUIRED. PERSPECTIVE PICTURES WERE PLOTTED USING THE ALGORITHMS DEVELOPED IN THIS STUDY AND DATA COLLECTED FROM TYPICAL ROADWAYS, AND ARE INCLUDED IN THE APPENDIX OF THE REPORT. A CALCOMP MODEL 565 DIGITAL PLOTTER LINKED TO AN IBM 1401 DIGITAL COMPUTER WAS USED TO DRAW THE INDIVIDUAL ROADWAY PLOTS. /BPR/
