  We investigate the possibility to use macroscopic information to improve
control performance of a vehicular platoon composed of autonomous vehicles. A
general mesoscopic traffic modeling is described, and a closed loop String
Stability analysis is performed using Input-to-State Stability (ISS) results.
Examples of mesoscopic control laws are provided and shown to ensure String
Stability properties. Simulations are implementedin order to validate the
control laws and to show the efficacy of the proposed approach.
