DISPERSION OF HIGHWAY TRAFFIC BY TIME PERIODS

IT IS ASSUMED THAT IF SAMPLE RECORDS OF HIGHWAY TRAFFIC BE CONFINED TO CERTAIN HOURS OF THE DAY, DAYS OF THE WEEK, AND MONTHS OF THE YEAR, THE DISPERSION WILL BE LESS THAN IF THE OBSERVATIONS ARE TAKEN AT RANDOM THROUGH THE YEAR. FOR HOLLAND TUNNEL AND GEORGE WASHINGTON BRIDGE CALCULATIONS SHOW THAT FROM 8 TO 12 IN THE MORNING AND FROM 3 TO 7 IN THE AFTERNOON ARE THE BEST HOURS OF THE DAY. FOR THE MONTHS, JULY, JUNE, AUGUST AND MARCH ARE THE MOST NEARLY CONSTANT IN HOURLY VARIATIONS, WHILE APRIL AND MAY AND SEPTEMBER THROUGH NOVEMBER ARE MORE HIGHLY VARIABLE. OF THE DAYS OF THE WEEK WEDNESDAY AND SATURDAY ARE BEST AND MONDAY AND TUESDAY MOST VARIABLE. /AUTHOR/
