need in several local comprehensive plans, long-range transportation plans and expressway authority master plans. As a result, the parkway extension and remaining portions of the Osceola County Expressway Authority (OCX) 2040 Master Plan was incorporated into the CFX 2040 Master Plan. CFX recently completed a Concept, Feasibility and Mobility Study for the Poinciana Parkway Extension that concluded the project may be viable under CFX policy. The CFX Board accepted that study's findings and approved a Project Development & Environment (PD&E) project at their Board meeting on March 8, 2018.
2045 Cost Feasible Model w/ Base Year Model Calibration was used for the future year AADTs. The NCHRP smoothing method was applied to the projected volume. After the AADTs were established, the K-factors and D-factors recommended for the project were applied to calculate the demand in the peak hour according to the existing peak direction. The K-factor and D-factor are same as those used in the base year volume development. The AADTs ranged from 17,500 to 63,000 along US 27 within Highlands County. Highest AADTs were observed around Sebring area, south of SR 66, Avon Park and Highlands/Polk County line.
Figure 8-4 depicts the ranges of AADTs along US 27 within the study area in Highlands County. Figure 8-5 shows the peak hour LOS along US 27 and Figure 8-6 shows the daily truck volume. 2045 Daily Truck Volume is calculated by multiplying 2045 AADT from D1RPM and 2023 T-factors from FTO. Table 8-3 shows the peak hour LOS for sections along US 27 for No-Build 2045.
Segments are divided based on the number of lanes, functional classification of roadways and the resulting LOS. Segments of US 27 operate with volume-to-capacity (V/C) ratio over 1.0 in 2045 indicating a congested transportation system. FDOT Topic No. 525-000-006 provides LOS targets for the State Highway System (SHS). For US 27, acceptable Level of Service Standard is "D". The AADTs in the No-Build alternative ranged from 17,500 to 63,000 along US 27. Additional capacity or alternative route(s) are needed to address this increase in demand and growth of the region.
