SUN SHADOW PATTERNS ON HIGHWAY SIGNS

WELL-KNOWN, PREDICTABLE, AND WIDELY USED SUN-TIME RELATIONS HAVE BEEN ADOPTED TO DEVELOP A COMPUTER PROGRAM THAT WILL PRODUCE VALUES WHICH MAKES EXTREMELY SIMPLE CALCULATIONS FOR SUN SHADOW PATTERNS POSSIBLE. THE PROGRAM WILL FURNISH PRECISE DATA FOR ANY LATITUTDE AND SIGN SURFACE ORIENTATION. THE RESULTS OF THIS STUDY ARE GENERAL, BUT MAY BE EASILY EXTENDED TO EMBRACE VARIOUS DESIGN PARAMETERS. IN ADDITION, STATISTICAL DATA CONCERNING CLOUD COVER AND OTHER CLIMATOLOGICAL DATA MAY BE READILY INCORPORATED INTO THE INPUT DATA FOR THE PROGRAM. /AUTHOR/
