Leveraging Connected and Automated Vehicles for Speed Harmonization

This paper proposed a speed harmonization controller for partially connected and automated vehicles. It regulated the flow rate of the entire traffic by adjusting only the target cruising speed of Connected and Automated Vehicles (CAVs). To evaluate the proposed controller, a VISSIM based microscopic simulation evaluation was conducted. Sensitivity analysis was performed for CAV Penetration Rate (PR), demand level (v/c ratio) and target drop rate of demand. Results confirm that the control accuracy of the proposed controller is over 80% across all CAV PRs, demand levels and target drop rates of demand.
