SPR-5021: Traffic Signal Freight Prioritization via Vehicle to Infrastructure (V2I) Communications

This project will development and evaluate traffic signal freight prioritization utilizing third party in-cab alerts provider. This V2I application will communicate with the signal controller to extend green time for slower moving freight entering the decision zone with the objective of reducing hard braking and slower start-ups at intersections along the corridor. The communication latency (and needs) will be evaluated. This project will use and evaluate, commercial cellular infrastructure for both the communication to the trucks (in cab devices provided by Drivewyze) and communication to the traffic signal cabinets (INDOT cellular modems).
