DISPERSION OF HIGHWAY TRAFFIC VOLUME BY TIME PERIODS-NINE STATIONS IN MICHIGAN

THE RELATIVE STATISTICAL DISPERSION OF HIGHWAY TRAFFIC FOR THE HOURS FROM 9 TO 10 IN THE MORNING TO 5 TO 6 IN THE AFTERNOON IS MUCH LESS THAN FOR THE REMAINING HOURS OF THE DAY. THIS DAY PERIOD IS ALSO CONVENIENT FOR TRAFFIC COUNTING, AND THE GREATER THAN AVERAGE CONSTANCY OF FLOW OF TRAFFIC MAKES INCREASED PRECISION OF ESTIMATE FEASIBLE. IN RESORT AREAS AND OTHER AREAS OF WIDE DISPERSION ON WEEKEND DAYS, IT MAY ALSO BE DESIRABLE TO USE ONLY MIDWEEK DAYS FOR ESTIMATION OF TRAFFIC VOLUME. AMONG THE MONTHS, JUNE, JULY, AND AUGUST HAVE THE MOST NEARLY CONSTANT FLOW OF TRAFFIC, BUT AMONG THE OTHER MONTHS THERE IS LITTLE CHOICE FOR SAMPLING PERIODS. /AUTHOR/
