Effect of Heavy-Truck Platooning Fuel-Efficiency Gains on Overall Fuel Efficiency
Transportation Research Record: Journal of the Transportation Research Board, 2019 Many studies addressing the fuel-efficiency gains derived from heavy-truck platooning operations have shown that it is possible to achieve increases in fuel efficiency of 10% or more. These studies focus only on the gains realized while traveling under platooning conditions (i.e., highway speeds sustained for sizable intervals of time). However, heavy-
