DISPERSION OF HIGHWAY TRAFFIC BY TIME PERIODS

THE DISPERSION OF HOURLY VOLUME OF HIGHWAY TRAFFIC FOR THE HOURS FROM 9 TO 10 IN THE MORNING TO THOSE FROM 5 TO 6 IN THE AFTERNOON IS FAR LESS THAN FOR THE REMAINING HOURS OF THE DAY. THIS IS TRUE FOR RURAL STATIONS OF SMALL TRAFFIC VOLUME AS WELL AS FOR DENSE TRAFFIC. SINCE ROUGHLY HALF OF THE TRAFFIC MOVES DURING THE OTHER HOURS, AN INCREASE IN PRECISION OF ESTIMATE CAN BE OBTAINED BY RESTRICTING SAMPLING TO THE HOURS OF SMALL DISPERSION AND BY THE USE OF TRAFFIC PATTERNS, FROM WHICH THE ERROR OF ESTIMATE OF THE MEAN IS LESS THAN FOR THE HOURS OF LARGE SCATTER. THESE RESULTS ARE PRESENTED IN SEVEN CHARTS AND TEN TABLES OF STATISTICAL MEASURES. /AUTHOR/
