A METHOD OF ESTIMATING TRAFFIC BEHAVIOR ON ALL ROUTES IN A METROPOLITAN COUNTY

THE ANNUAL AVERAGE DAILY TRAFFIC VOLUMES /ADT/ OF TWO ROUTES MAY BE IDENTICAL BUT THEIR TRAFFIC PATTERNS MAY BE COMPLETELY DIFFERENT. PEAK TRAFFIC VOLUMES ON RECREATIONAL ROUTES DURING SUMMER ARE TWO TO FIVE TIMES HIGHER THAN THE ADT, WHILE TRAFFIC VOLUMES ARE RELATIVELY STEADY THROUGHOUT THE YEAR ON ROUTES WITH PREPONDERANTLY BUSINESS TRAFFIC. IT IS THEREFORE IMPORTANT TO KNOW THE TRAFFIC CHARACTERISTICS OF THE DIFFERENT ROADS IN A HIGHWAY NETWORK. CRITERIA ARE GIVEN FOR CLASSIFYING ROUTES INTO TYPES BY TRAFFIC CHARACTERISTICS. THE ALLOCATION OF ROAD SECTIONS TO THESE DIFFERENT TYPES IS AN OBJECTIVE GROUPING BASED ON MACHINE TRAFFIC COUNTS IN MAY, JUNE AND AUGUST, AND INTERVIEWS ARE NOT REQUIRED. A COUNTING AND EVALUATING PROCEDURE WITH BUILT -IN STATISTICAL CONTROL HAS BEEN DEVELOPED. THE METHOD DEVELOPS FACTORS FOR EACH OF FOUR ROUTE TYPES. THE FACTORS ALLOW ESTIMATION OF ADT AND PEAK HOUR TRAFFIC WITH STATISTICALLY ESTIMATED ACCURACY. THE NUMBER OF SAMPLE COUNTS NECESSARY FOR DIFFERENT LEVELS OF ACCURACY ARE PRESENTED BY ROUTE TYPE SO AS TO MATCH THE DIFFERENT ACCURACY NEEDS OF THE ASSIGNMENT PROCEDURE.
