Operational Performance Evaluation of the Managed Lane Strategy for Early Deployment of Cooperative Adaptive Cruise Control

This study examines the potential for improved operational performance in terms of increased throughput and capacity resulting from the deployment of connected and automated vehicles (CAV) equipped with cooperative adaptive cruise control (CACC) on managed lane facilities (CAV-ML). Despite the low projected market penetration of CAVs during the next decade, the use of managed lane facilities has the potential to support the realization of increased mobility benefits by their very nature. The goals of this study are to 1) estimate capacity shifts under different high-occupancy vehicle/high-occupancy toll and CAV traffic mixes, providing operational insights and guidance for traffic management centers to control the volume on the managed lanes to maintain desired speed; 2) evaluate the impact of on/off ramp density on operational performance, giving recommendations under different traffic conditions; and 3) evaluating the impacts of the CACC strategy on the I-66 managed lane network.
