PT Engineering provided NCDOT Program Management services for the development of microscopic simulation models in TransModeler. The simulation models were used to screen potential project for SPOT 5.0 and determine the travel time savings component for scoring in the NCDOT Prioritization Process. PT Engineering was responsible for overseeing the analysis of 90 projects in TransModeler, including the development of influence areas for the projects, scoping of the studies, quality control review of the models and the development of the technical approach for the program. PT Engineering also developed the procedure for analyzing ramp metering projects in TransModeler as part of the study.
