LEGEND
PHV - Peak Hour Volume (afsc Design Hourly Volume equivalent)
Adjustment for Right Turns
For posted speeds at or under45 mph, PHV right turns > 40, and
PHV total < 300.
Adjusted right turns = PHV Rigit Turns - 20
I PHV is not known use formula: PHV = ADT x K x D
K = the percent of AADT occurring in the peak hour
D = the percent of traffic in the peak direction of flow
Note: An average of 11%for Kx D will suffice.
