Abstract With the development of autonomous bus (AB) technology, flexible marshaling strategies based on platooning with different numbers of buses have been proposed. However, the environmental benefits of platooning have been ignored or set to a fixed value. Therefore, a methodology is proposed to measure the AB energy consumption considering platooning. First, the lattice Boltzmann method (LBM) is used to explore the impact of platooning on aerodynamics. Second, vehicle specific power (VSP) is introduced to quantify the environmental characteristics of the AB in a single-bus scenario. Third, an energy consumption model that considers platooning is developed. Finally, the environmental benefits of AB platooning are discussed under different conditions while considering speed, acceleration, and spacing. The results show that platooning can significantly improve the environmental benefits of ABs under conditions of close spacing and high speed. This study supports the further development of platooning control algorithms and AB operation strategies.
