Simulation Framework for Vehicle Platooning and Car-following Behaviors Under Connected-vehicle Environment

This paper studies the traffic assistance system consisting of different kinds of vehicles (manual, Adaptive Cruise Control (ACC) and Cooperative Adaptive Cruise Control (CACC) vehicle). By using the application programming interface in microscopic-traffic simulation, the aim that constructing simulation framework of CACC platoon is achieved. Maneuvers like forming, adjusting, splitting, dismissing and joining in a platoon are implemented under the simulation platform. Then a platoon with 6 CACC vehicles is simulated to examine the interactions in a platoon and how they react to shockwaves microscopically, which in turn verify the driver model partly. Finally different market penetration and platoon size of CACC are tested. Results illustrate the lane capacity increased significantly when market penetration of CACC vehicles added, however platoon size have little impact on traffic capacity. These preliminary working will be a foundation for our future work in this area.
