The Cooperative Adaptive Cruise Control (CACC) system has been regarded as an effective solution to increasing the traffic flow efficiency. Today, more and more focus has been concentrated on the environmental sustainability of a CACC system, but very few of them have explored the system-wide strategies to optimize the global environmental sustainability performance of a CACC system, e.g. how to determine the most energy-efficient sequence of vehicles during the lifecycle of a platoon. In this research, we synthetically analyze the platoon-wide impact of the disturbances when vehicles join and leave the Eco-CACC system. A bi-level model is developed to investigate the optimal intra-platoon vehicle sequence (i.e. position in the platoon) when each vehicle joins the platoon to minimize the total of all acceleration, deceleration and cruising maneuvers of the entire platoon. In the lower level, we formulate sub-problems for platoon joining and splitting to figure out minimal energy consumption for gap closing and opening. In the upper level, the set of vehicles' positions when joining the platoon is optimized to determine the most energy-efficient vehicle sequence during the lifecycle of a platoon. Simulation studies of different scenarios are conducted using MATLAB/Simulink. As shown in the numerical results, the optimal solution leads to 51–77% saving on incremental energy consumed from gap opening and closing.
