Standard Level of Service for the particular roadway as adopted and documented in the Hillsborough County Comprehensive Plan. The LOS for roadways within incorporated areas is governed by the jurisdiction’s Comprehensive Plan and may differ from this report. Local Functional Class - The assignment of roads into systems according to the character of service they provide in relation to the road network. The abbreviations are: PA - Principal Arterial, A - Arterial, C - Collector.

10 PkHrDir Vol
Peak Hour Peak Direction Volume - The 100th highest hour traffic volume determined by (AADT x K100 x Directional Factor).
Maximum Service Volume (Daily Capacity) - The maximum rate of flow at which vehicles can traverse a point or uniform segment roadway and maintain the performance standard as measured by speed for interrupted flow facilities and V/C ratio for uninterrupted flow facilities during the daily (AADT) period. Peak Hour Peak Direction Maximum Service Volume (Capacity) - The Peak Hr Dir Cap is the maximum rate of flow at which vehicles can traverse a point or uniform segment roadway and maintain the performance standard as measured by speed for interrupted flow facilities and V/C ratio for uninterrupted flow facilities during the peak hour period for the peak direction. Volume over Capacity - PM Peak Hour Directional Volume to capacity of the roadway. V/C greater than 1.0 indicates a roadway exceeds the available capacity.
