2. EXISTING CONDITIONS
III. Traffic Volumes and Characteristics Traffic data and characteristics for the study area were obtained from available sources [i.e., FDOT Florida Traffic Information & Highway Data (2016)] and Hillsborough County 2017 Level of Service Report. A facility inventory within the study corridor was compiled from existing conditions. The data compiled in Table 2-2 includes the Level of Service (LOS) standard, maximum service volumes (MSVs), and the 2017 Annual Average Daily Traffic (AADT), among other metrics. The LOS is determined using the Generalized Service Volume Tables from FDOT’s 2013Quality Level of ServiceHandbook. It should be noted that the results shown in Table 2-2 are for general planning purposes only. Historical traffic characteristics for E. 131 st Avenue can be found in Appendix VI . The latest version of the Tampa Bay Regional Planning Model (TBRPM v8.2) was utilized to review the future year daily traffic projections. The TBRPM is based on the Florida Standard Urban Transportation Model Structure (FSUTMS)
and is recognized by both FDOT District Seven, as well as the Tampa Bay Area Metropolitan Planning Organizations (MPO) as the accepted travel demand forecasting tool. The roadway network used reflects the latest available adopted Cost Affordable LRTPs for all counties in the region. The Peak Season Weekday Average Daily Traffic (PSWADT) volume obtained from the 2040 year model was converted to the respective AADT volumes through multiplication by a factor of 0.96, which is the Model Output Conversion Factor (MOCF) for Hillsborough County. The model volumes were validated based on 2010 TBRPM data. NCHRP Report 765 was used to adjust the future traffic forecast. The FSUTMS model plots and other documents are attached in Appendix VI . Table 2-3 provides a summary of the projected volumes along the corridor.
