Abstract:The purpose of this document is to describe the research, including simulations and a field experiment, involving the operation of connected and automated vehicles (CAVs) on managed lanes. The scenarios associated with this concept were chosen and designed to facilitate rapid and successful deployment of a solution that is not yet in use. The proposed operation involves deploying platoons of CAV-equipped vehicles that are governed by an integrated set of speed-harmonization, cooperative-merge, and cooperative-adaptive-cruise-control (CACC) applications. The concept accounts for CACC-vehicle behaviors in the vicinity (both upstream and downstream) of managed-lane entry ramps. The concept further addresses platooning and cooperative merging on the managed lane. The concept was simulated, and potential improvements were quantified. The results were then implemented in a small number of real vehicles and tested on a real roadway under controlled conditions and in mixed traffic.
