Table 350
Hourly Percentages Compiled for Total Vehicles
The following table shows hourly percentages of total vehicles sorted by Traffic Pattern Group
(TPG) for the year 2015. Factors from this table are applied to raw traffic counts of less than 24
hours, which may include volume counts (axle and loop), automatic vehicle classification (AVC),
or manual classification counts. Hourly percentages from this table are applied to the known
hour periods of the raw count, converting it to a 24-hour total.
The factors were developed using the Department’s Traffic Data System (TDS) Statistical
Analysis tool. Raw count data from 2,000 AVC counts, collected statewide and averaged over
the last five years, was assigned to the respective TPG and a summary was produced showing
the hourly percentage tables by direction (applied to divided roadways).
