Average Annual Daily Traffic (AADT)
It is the average daily volume (24 hr) at a given location over a whole year.

Average Annual Weekday Traffic (AAWT)
The average 24 hour volume occurring on weekdays for a whole year (365 days).

$$AAWT = \frac{\text{vehicle passing a point}}{\text{weekdays}} $$

$$AAWT = \frac{\text{N}}{260} $$

Average Daily Traffic (ADT)
It is the average 24 hour volume at a given location over a defined time period less than a year.

Average Weekday Traffic (AWT)
The average 24 hour weekday volume at a given location over a defined time period less than a year.

Peak Hour
The single hour of the day that has the highest hourly volume is referred to as the peak hour.

Peak Hour Factor (PHF)
It is used to describe stability of volume distribution in an hour.

$$PHF = \frac{\text{Hourly Volume}}{\text{Max Flow Rate}} $$

The maximum possible value for PHF is 1.
