Traffic Stream Parameters[edit]

Daily Volumes[edit]

It is the average daily volume (24 hr) at a given location over a whole year.^[1]

The average 24 hour volume occurring on weekdays for a whole year (365 days).^[2]

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

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

It is the average 24 hour volume at a given location over a defined time period less than a year.^[3]

The average 24 hour weekday volume at a given location over a defined time period less than a year.^[4]

The single hour of the day that has the highest hourly volume is referred to as the peak hour.^[5]

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.
