INTRODUCTION The 2017 Roadway Level of Service Report is a comprehensive listing of major roadways and their operating conditions, which provides the current levels of service of roadways 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 peak hour, peak direction Level of Service (LOS) standards from the Transportation Element of the adopted Hillsborough County Comprehensive Plan; and has been generated using the current guidelines of the 2012 edition of the FDOT (LOS) Generalized Tables and Highway Capacity Manual (HCM). The LOS 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 peak hour peak direction volumes and 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. This current edition of the Hillsborough County LOS Report will provide a basis for Average Annual Daily Traffic (AADT). These counts are to be used for general infrastructure planning purposes. Any counts, especially those older than two years, can be updated using the above mentioned acceptable traffic analysis techniques, which may include more detailed analysis involving peak hour counts. 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 makes extensive use of statewide default values and is intended for generalized analysis and initial problem identification. It should only be used as a guide and reference, and should be supplemented with a more detailed study to more accurately determine LOS.
This report consists of County Roads, State Roads, and Appendices:
County Roads:
Provides the LOS for all the major roadways within Unincorporated Hillsborough County as well as several major County
maintained roadways located in the cities of Tampa, Plant City, and Temple Terrace. State Roads:
Provides LOS for all roadways that are part of the State Highway System within unincorporated Hillsborough County.
Appendices:
Appendix A – Legend of Variables Used in the Roadway LOS Report Appendix B – Definition of Level of Service (LOS) Appendix C – Level of Service (LOS) Standards, High Transit Roadways and Updated Regulated Roads
Appendix D – Community Planning Areas Appendix E – FDOT 2012 Generalized Tables
