The case for heavier goods vehicles – some new evidence [PDF]
The Armitage Inquiry found that an increase in maximum gross vehicle weights to 34 tonnes on 4 axles, 38 tonnes on 5 axles and 44 tonnes on 6 axles would permit a reduction in the size of the heavy articulated vehicle fleet of some 13%.

Heavy Vehicles: Distributed Hybrid Power System and Vehicle
This research focuses on the development of a distributed hybrid power system and vehicle for heavy vehicles. The dynamical system comprises a power plant module, a drive module, an energy-storage module, and an entire car controller. The power plant module consists of one or more auxiliary power units that provide power to the heavy vehicle's power ...

Cooperative look-ahead control for fuel-efficient and safe heavy-duty vehicle platooning [PDF]
The operation of groups of heavy-duty vehicles (HDVs) at a small inter-vehicular distance (known as platoon) allows to lower the overall aerodynamic drag and, therefore, to reduce fuel consumption and greenhouse gas emissions.
