1 Roadway (From/To): The common name assigned to the road segment (street name), the cross street or location at which the segment begins, and the crossing street or location at which the segment ends. 2 Reg (Regulated Roadways): Roadways that are considered as part of the Concurrency Management System and defined in the Adequate Public Facilities Ordinance (“Y”- Yes, “N”- No). 3 FC (Functional Classification): The assignment of roads into systems according to the character of service they provide in relation to the total road network. The abbreviations used for the FC are: PA – Principal Arterial MA – Minor Arterial MAC – Rural Major Collector C – Collector MIC – Rural Minor Collector F – Limited Access 4 Road Type (Existing Road System/Type): Existing number of lanes and whether the facility type is Divided (D), Undivided (U), One Way (O), or Freeway (F). 5 Spd Lmt (Speed Limit): Speed limit currently posted for the roadway. 6 LOS Std. (Level of Service (LOS) Standard): The LOS Std. 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. The LOS standards in this report may differ. See Appendix C - Level of Service (LOS) Standards.
7 Len (mi): The Length of the roadway segment specified in miles. 8 Sig/Mi (Number of Signals per mile on the Segment): The number of signalized intersections per mile on a roadway analysis segment as identified in this report. 9 AADT (Annual Average Daily Traffic): The AADT is the number of vehicles that travel on a specified segment of a road on an average day. For aggregated segments, traffic counts may be weighted according to the length of each individual link and may not match a specific count. 10 Daily Cap (Daily Capacity): The Daily 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 daily (AADT) period. 11 Peak Hr Dir Vol (Peak Hour Directional Volume): The 100th highest hour traffic volume determined by (AADT x K 100 x Directional Factor). 12 Peak Hr Dir Cap (Peak Hour Directional 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.
