The problem of controlling traffic using connected automated vehicles is approached by utilizing Lagrangian traffic models. A continuum model with time delay is introduced in the Lagrangian frame in order to capture the open loop dynamics of the traffic behind a vehicle of prescribed motion. The stability of the open loop system is analyzed and compared to that of a benchmark car-following model. Finally, the Lagrangian traffic models are used to propose a longitudinal controller for connected automated vehicles that allows them to respond to connected vehicles behind to stabilize the upstream traffic in a closed loop fashion.
