STANDARD DEVIATION AND COEFFICIENT OF VARIATION OF AUTOMATIC TRAFFIC RECORDER COUNTS

THIS PAPER PRESENTS A BRIEF DESCRIPTION OF THE DATA OBTAINED IN THE OPERATION OF FIXED AUTOMATIC TRAFFIC RECORDERS, AND OF THE STATISTICS READILY DERIVED FROM THESE DATA THROUGH SIMPLE TABULATION AND CALCULATION; IT DESCRIBES THE PROCEDURE USED BY IOWA STATE HIGHWAY COMMISSION FOR A MORE THOROUGH STATISTICAL ANALYSIS OF THESE DATA AND DISCUSSES THE SIGNIFICANCE OF THE STATISTICS AVAILABLE FROM THIS ANALYSIS. EMPHASIS IS PLACED ON THE SIGNIFICANCE AND UTILITY OF THE STANDARD DEVIATION AND THE COEFFICIENT OF VARIATION OF THE RECORDER COUNTS. IN THIS PROCEDURE, PROVISION IS MADE FOR THE CALCULATION OF THE STATISTICS FOR EACH HOUR OF THE DAY FOR THE WEEK DAYS OF EACH MONTH OF THE YEAR. WHEN AVAILABLE FOR A COMPLETE YEAR THE STATISTICS REVEAL THE MONTHS OF THE YEAR, THE WEEKS OF THE MONTH, THE DAYS OF THE WEEK AND THE HOURS OF THE DAY UPON WHICH THE LEAST VARIABLE AND CONSEQUENTLY MOST RELIABLE SHORT COUNTS MAY BE MADE. /AUTHOR/
