DESCRIPTION:This presentation will discuss the most important factors that
  influence the energy consumption of road freight transport.  These includ
 e: vehicle engine efficiency\; aerodynamic drag and rolling resistance\; v
 ehicle configuration (number of vehicle units)\; traffic congestion\; spee
 d\; payload factors and the use of regenerative braking.  In particular it
  highlights the importance of both logistical factors and vehicle engineer
 ing. \n\nThe presentation will conclude that improving engine efficiency\,
  rolling resistance and aerodynamic drag can yield relatively small improv
 ements in fuel consumption\, compared with the other factors.   Larger veh
 icles are always significantly more energy efficient than smaller ones whe
 n fully loaded and transferring freight from articulated vehicles onto sma
 ller rigid vehicles for urban deliveries typically increases fuel consumpt
 ion by approximately 35%.  Running vehicles partially loaded can increases
  the energy per unit freight task by as much as 65%.  Finally\, for urban 
 start-stop conditions\, use of regenerative braking systems can reduce hea
 vy vehicle fuel consumption by 25-35%.
