area comparing the model volumes and the observed traffic counts and Streetlight Data. Scatter plots comparing the traffic counts to the model volumes for the subarea along with the R-squared value.
Review the 2045 Cost Feasible model for planned roadway improvements, anticipated regional growth of population and employment. BEBR projections for County data will be compared for the limits that are within the subarea model network. In addition, TAZs within the land use study area will be reviewed and updated as necessary to reflect projected 2045 conditions. Known Development of Regional Impact (DRIs) or other regional significant developments within the study area will be analyzed to ensure that they were properly accounted for in the SE data based on their build-out capacities and dates. For the limits that are within the subarea model network, any adjustments necessary to the total population and employment growth by TAZ between 2015 and 2045 will be updated in coordination with the review agencies.
The No-Build and two (2) Build forecast alternatives (Widening of US 27 general-purpose lanes, and Limited-access toll facility alternative on US 27) will be coded and run. Coordinate with FDOT to determine the appropriate access points and the toll rates to be utilized for the project corridor as part of the alternatives analysis development. A toll plan including the toll lane access points will be developed along the existing corridor for illustration. Results will be reviewed and summarized.
Model AADT values will be used to estimate daily volume along corridors. Base year DDHVs will be developed using K and D values recommended from the 2019 Traffic Forecasting Handbook. Model-derived hourly volumes will be compared to traffic counts to identify any necessary adjustment (diurnal) factors.
A base year capacity analysis will be conducted using FDOT Quality Level of Service (QLOS) Handbook Generalized Service Volumes Tables (GSVT) with hourly base year link volumes.
The 2045 Cost Feasible model will be compared against BEBR projection within subarea. Subarea daily traffic (2045) will be compared for reasonableness. 2045 bidirectional peak hour volumes (DHVs) will be estimated by applying diurnal factors to 2045 model AADT values. Any further adjustments necessary to either daily or peak hour traffic volumes will be coordinated with FDOT. Traffic projections will be provided comparing 2045 No-Build and 2045 Build scenarios.
Design year capacity analysis will be conducted using FDOT Quality Level of Service (QLOS) Handbook Generalized Service Volumes Tables (GSVT) with hourly design year link volumes. Alternatives will also be compared by calculating volume/percent change. Corridors including US 17, Sebring Parkway/Panther Parkway, SR 17, CR 671, and MLK Jr Blvd/Power Line Road will be evaluated to determine whether the existing facilities can accommodate anticipated demand. Any ongoing studies will be taken into consideration and are not expected to be affected by this study.
Based on the results of the No-Build analysis, improvement alternatives will be developed and evaluated in coordination with other engineering and environmental sections. The evaluations will identify potential impacts associated with various alternatives, including impacts to other regional facilities in the project.
