INTRODUCTION The 2014 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 2014 and additional counts are to be taken May of 2015 and September of 2015. As counts are collected the report will be updated to include the most recent counts. State roads were 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 Level of Service (LOS) Generalized Tables and Highway Capacity Manual (HCM). 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. The LOS for the State Roads was calculated using average daily volumes and capacities based on FDOT’s recommended methodology. Roadways included in this inventory are regulated arterials and collectors as defined in the Hillsborough County Comprehensive Plan. These are roads located in unincorporated Hillsborough County and are regulated according to the inventory. The regulated roads in the unincorporated areas are part of the Concurrency Management System and are subject to the requirements for public facilities identified in the Hillsborough County Land Development Code. 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, and as described in the Concurrency Management System Administrative Procedures Manual. 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 in traffic studies for Concurrency Application Review. 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. 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 for use in concurrency analyses, except where indicated that a detailed analysis has been provided. As new information becomes available, this report will be updated. Determining Available Roadway Capacity - The County’s Adequate Public Facilities Ordinance, Part 4.02.00 of the Land Development Code, requires that there be sufficient roadway capacity to accommodate development before building certificates are issued. This Hillsborough County Roadway Level of Service Report will be used to determine initial highway volumes and capacities. The report does not account for all trips from projects that have received certificates of capacities, but have not received their certificates of occupancy. These trips are
