Abstract
The vehicle industry is always in search of breakthrough energy-saving and emission-reduction technologies. In
recent years, vehicle intelligence has progressed considerably, and researchers are currently trying to take advantage of these developments. Here we consider the case of many vehicles forming a queue, i.e., vehicles traveling at
a predetermined speed and distance apart. While the majority of existing studies on this subject have focused on
the influence of the longitudinal vehicle spacing, vehicle speed, and the number of vehicles on aerodynamic drag
and fuel economy, this study considers the lateral offset distance of the vehicle queue. The group fuel consumption savings rate is calculated and analyzed. As also demonstrated by experimental results, some aerodynamic
benefits exist. Moreover, the fuel consumption saving rate of the vehicle queue decreases as the lateral offset distance increases.
