This project is focused on enhanced modeling, continued monitoring, and assessment of a large work zone project in Raleigh, North Carolina. The work zone project covers work to be completed under TIP numbers I-5311/I-5338: I-40 and I-440 Re-Construction Work from Exit 293 to I-40 Exit 301 and I-440 Exit 14. Through this project, the ITRE team will use current performance data extracted from Traffic.Com, Inrix, and overhead video cameras to collect and analyze performance data for key corridors across the network, including the primary work zone corridor and critical diversion routes. These data will be used to calibrate simulation models to the observed conditions, which will enable the team to offer assistance in responding to observed choke points in the network.
