“…Therefore, we refer to the structure of traffic control as virtual ring. The concept of virtual ring appeared in the experiments of [3] and the analysis of [4,37]. Below we build on these works and give a more detailed analysis.…”

“…The concept of virtual rings have been introduced in the experiments of [3] where three vehicles performed car following on a straight highway, with the first vehicle responding to the last one. This concept was further discussed in the context of traffic control in [4,37], and also utilized in [54] where the so-called leading cruise control was introduced for high-connectivity penetration scenarios.…”

“…Here we further elaborate the concept of virtual rings and Lagrangian traffic control by CAVs. As opposed to previous works [37,54], we put more emphasis on the stability analysis of traffic flow, focus on low-automation and low-connectivity scenarios, and incorporate time delays associated with the response of vehicles, their controllers and the human drivers. We first introduce strategies for vehicle and traffic control, then highlight the benefits of connectivity-enabled feedback loops via simulations, and finally give a comprehensive stability analysis.…”

This work gives introduction to traffic control by connected automated vehicles. The influence of vehicle control on vehicular traffic and traffic control strategies are discussed and compared. It is highlighted that vehicle-to-everything connectivity allows connected automated vehicles to access the state of the traffic behind them such that feedback can be utilized to mitigate evolving congestions. Numerical simulations demonstrate that such connectivity-based traffic control is beneficial for smoothness and energy efficiency of highway traffic. The dynamics and stability of traffic flow, under the proposed controllers, are analyzed in detail to construct stability charts that guide the selection of stabilizing control gains.
