The regional existing year 2015 scenario was updated to validate the regional model to actual 2015 conditions. The overall modeling efforts included reviewing and updating the base year 2015 land use, roadways, and reviewing the base year 2015 traffic counts and locations.
The 2015 AADT counts in the D1RPM are reviewed using historical AADT data obtained from FTO. For the model validation, the 2015 AADT counts are compared with the model output volumes for validation.
The model parameters were reviewed in this validation process.
The travel demand model forecasts future year auto and truck trips, and travel patterns, congestion and delay on along US 27. Forecasted demand and the associated Level of Service is used in identifying the proposed strategies are most effective in reducing future year congestion and delay on US 27 in the Highlands County.
The analysis of corridor needs will go through a structured process of characterizing existing and projected corridor conditions, evaluate improvement options and its performance measures such as level of service, and evaluate potential corridor improvements against these performance measures to develop a set of recommended improvements.
