Abstract
VEHICULAR TRAFFIC VOLUME IS ESTIMATED THROUGH A SERIES OF GRAPHIC ANALYSES OF VEHICULAR TRAFFIC CYCLES OF DIFFERENT LENGTHS (MONTHLY, DAILY, AND HOURLY), DEPICTED SCHEMATICALLY BY MEANS OF TRAFFIC PATTERNS WHICH REFLECT MOTORISTS' TRAVEL HABITS. CONCLUSIONS INCLUDE THE FOLLOWING: (1) TRAFFIC VOLUMES FOR MAY AND OCTOBER WERE FOUND TO BE CLOSEST TO THE AVERAGE FOR THE YEAR; (2) MONTHLY TRAFFIC VOLUMES REFLECTED THE EFFECTS ON TRAFFIC OF THE ECONOMIC DEPRESSION AND SUBSEQUENT BUSINESS RECOVERY, THE EFFECTS OF NEW ALTERNATE ROUTES, AND ADVERSE WEATHER CONDITIONS; (3) WEEKDAY TRAFFIC VOLUME IS NO INDICATION OF WEEKEND VOLUME; AND (4) THE TRAFFIC VOLUME ON WEDNESDAY IS THE AVERAGE FOR THE WEEK. /AUTHOR/
