Abstract: Cooperative vehicle platooning enabled by connected automated vehicle (CAV) technology has been identified to bring energy savings and driving-effort reduction. However, the intrinsic difference of gained benefits between the leading vehicle and the following vehicles hampers the spontaneous platooning via peer-to-peer coordination. This study proposes an auction mechanism that determines the leader–follower positioning together with the associated benefits, for facilitating the formation and maintaining the behavioral stability of vehicle platoons in a distributed way. We theoretically prove that there is no mechanism to achieve an efficient outcome in an ex post equilibrium, requiring individual rationality and budget balance. In this regard, we provide a truthful ε-approximate auction mechanism that deploys a linear transfer function, which guarantees that the implemented outcome is an efficient approximate dominant strategy equilibrium.
