INTRODUCTION The 2018 Roadway Level of Service Report is a comprehensive listing of major County and State maintained roadways within unincorporated Hillsborough County and their operating conditions based upon recent counts. The MPO conducted limited road counts May and September of 2015 and September of 2017. As counts are collected the report will be updated to include the most recent counts. State roads were are counted annually and provided by the Florida Department of Transportation (FDOT). This report uses the minimum Level of Service (LOS) standards from the Transportation Element of the adopted Hillsborough County Comprehensive Plan. The most recent version (03/14/2018) of the Florida Department of Transportation (FDOT) Generalized Annual Average Daily Volumes and Generalized Peak Hour Directional Volumes were used as a base to determine maximum service volumes (capacities) for both state and county maintained roadways within the county. The operating conditions for the State Roads was calculated using average daily volumes and capacities based on FDOT’s recommended methodology. Based on Hillsborough County’s methodology, a 95 percent adjustment factor was applied to all capacities on regulated roads in Unincorporated Hillsborough County. Roadways included in this inventory are regulated arterials and collectors as defined in the Hillsborough County Comprehensive Plan. Previous versions of the LOS Report assigned a general Level of Service (LOS) to each road segment based on where the counted AADT or peak hour/peak direction volume compared to the FDOT generalized tables described above. A better measure of effectiveness (MOE) related to the observed operations of a roadway segment is by measuring the volume to capacity (v/c) ratio. There is still a general correlation between v/c ratio and LOS that can be drawn. A v/c ratio of 1.0 or greater indicates that the counted volume exceeds the capacity of the road, which correlates to LOS F. As traffic counts, generalized service volumes, or other MOEs are updated and/or developed, the Roadway LOS Report will be updated accordingly. In accordance with Sec. 4.02.02 of the Hillsborough County Land Development Code, the FDOT Tables of Generalized Daily Level ‐ of ‐ Service Maximum Volumes will be used to determine initial highway capacities. The measurement of capacity may also be determined by substantiation in the form of engineering studies signed by a licensed Professional Engineer. Traffic analysis techniques must be technically sound and justifiable as determined by the County. Alterations to capacity on the State Highway System beyond ranges established by agreement between Hillsborough County and FDOT shall require FDOT review and approval. This report includes the inventory of all State and County collectors and arterials in unincorporated Hillsborough County, as well as support documentation.
