• Abstract:
  This project executed a preliminary experiment of vehicle-to-infrastructure (V2I)-based speed harmonization in which speed guidance was communicated directly to vehicles. This experiment involved a set of micro-simulation experiments and a limited number of prototype field runs. The simulation experiments produced mixed results in terms of system-wide benefits. The field runs demonstrated that connected and automated vehicles can successfully implement V2I-based speed harmonization and significantly reduce speed oscillations in their vicinity but do not have a significant impact on aggregate average speeds or travel times.
