PT Engineering was responsible for developing the traffic operations analysis in TransModeler for the planned addition of an auxiliary lanes between NC 147 and NC 55. The analysis included developing a calibrated model for 2 miles of freeway and 2 interchanges for the 2014 existing, 2040 No-Build and 2040 Build scenarios. Additionally, an interim year analysis was developed for 2025 and 2035 due to the I-40 mainline not being able to accommodate the future year build volumes.
