THE USE OF A DIGITAL COMPUTER WITH ELECTRONIC DISPLAY IN ROAD DESIGN

A COMPUTER PROGRAM BY THE AUTHORS, WHICH CALCULATES AND DOCUMENTS THE DESIGN OF A ROADWAY, HAS BEEN IN USE FOR SOME TIME. PART OF THE OUTPUT FROM THE PROGRAM CONSISTS OF GRAPHICAL REPRESENTATIONS OF LONGITUDINAL AND CROSS- SECTIONS OF THE ROAD. THIS GRAPHICAL OUTPUT TAKES SEVERAL HOURS TO PRODUCE ON DIGITAL GRAPH PLOTTERS. RECENT EXTENSION TO THE PROGRAM SUPPLEMENT THESE MECHANICAL UNITS WITH AN ELECTRONIC T. V. TYPE DISPLAY UNIT WHICH ENABLES THE ENGINEER TO FLIP THROUGH THE SERIES OF ROAD CROSS-SECTIONS IN MINUTES, CHECKING FOR ANY UNDESIRABLE ASPECTS OF THE DESIGN. A FURTHER FEATURE IS THE USE OF THE SAME UNIT TO DISPLAY A NUMBER OF PERSPECTIVE VIEWS OF THE ROAD AS SEEN BY A DRIVER. THESE CAN BE FILMED FOR ANALYSIS AT VARIOUS SIMULATED TRAFFIC SPEEDS. /A/RRL/
