“…Consequently, little technological and organizational improvements are identified. Fuel and emission efficiency values have remained almost constant and the potential benefits of technological innovations were not used to satisfy public interest (reduced greenhouse gas emissions and oil imports) [42]. There is need of new advanced technologies that have the potential to improve fuel economy and emissions characteristics of new HDV [43].…”

Purpose and methodology This paper summarizes the results of a permanent road freight sample survey carried out in 1997-2003 on heavy duty vehicles in Spain. In particular, this work reviews some of the key indicators that are measuring the efficiency and the operational performance of the freight road transport. The indicators of transport are coming directly and indirectly from the survey. The survey is based on a stratified random sampling, and represents an audit of the performance of 41,600 vehicles in a yearly basis.Main results Although the study shows wide variation in absolute values between 1997 and 2003, energy and environment efficiencies improve by 0.2%. Conclusions Nevertheless, assumptions and analyses of freight road transport in Spain find significant new points of view to the problems in order to assess vehicle utilization, fuel efficiency and CO2 emissions.

“…Manufacturers have significantly improved the technology of diesel engines and transmissions, which has enhanced engine efficiency. Through the new electronic injection systems and the introduction of the automatic gear box, engine efficiency has been improved by up to 30%, which has significantly reduced fuel consumption, subsequent emissions and related external costs (Saricks et al, 2003). Similarly, advances have been made in tyre technology, and rolling drag has been reduced.…”

“…The use of the vehicle's capacity depends on the levels of occupancy and load for each individual vehicle, the relative use of each type of vehicle, and the distribution of the different types of vehicles within the fleet of vehicles as a whole (Leonardi & Baumgartner, 2004). Additionally, the concept of environmental intensity must be defined for CO 2 and each of the air pollutants, as well as for noise and accidents (Saricks, Vyas, Stodolsky, & Maples, 2003). The energy and environmental intensities are measured in terms of energy consumption, emissions of CO 2 and each pollutant per tonne kilometre using the following equations:…”

“…The fundamental factors thus far described may vary depending on the industrial sector considered (Pimentel et al, 2004), the nature of the product distribution operation (Ang-Olson & Schroeer, 2002;Browne et al, 2005), the type of freight transported (Vanek & Campbell, 1999;Vanek & Morlok, 2000) and the type of vehicle used (Saari et al, 2007;Saricks et al, 2003). This study analyses the data for the freight transport sector as a whole, which includes both road and rail.…”

a b s t r a c tThis paper studies the external costs of surface freight transport in Spain and finds that a reduction occurred over the past15 years. The analysis yields two conclusions: trucks have experienced a reduction in external costs, and rail has lower externalities. The external costs of road freight transport decrease between 1993 and 2007 (44%). The external costs of rail freight increase by 12%. During this period, the external costs of road freight related to climate increase by 16%, oppositely than those from air pollution and accidents (51 and 44%). The external costs of rail related to pollutant emissions and climate increase by 4% and 43%. Oppositely, the external costs related to accidents decrease by 27%. Road freight generates eight times the external costs of rail, 2.35 Euro cents per tonne kilometre in 2005 (5.6% accidents, 74.7% air pollution and 19.7% climate) vs. 0.28 (13.4% accidents, 53.9% air pollution and 32.7% climate).

“…In that sense, with using the Exhaust gas recirculation system, in the first decade of the 21st centur y, fuel consumption decreased by an additional 6% (Federal Railroad Administration, 2009). (Saricks et al, 2003) point out that aerodynamic devices on the vehicle can increase energy efficiency. Besides that, higher energy efficiency can be achieved by reducing the vehicle weight (Maintenance Council, 1998), as well as using wide-based tires instead of using double wheels (Federal Railroad Administration, 2009).…”

Influence of Vehicle Procurement on the Vehicle Fleet Energy Efficiency

Abstract:In this paper, the vehicle procurement is considered as a factor which influences the vehicle fleets energy efficiency. Vehicle fleet managers in transport and logistics companies with their own fleet for freight transport often make a decision to procure an appropriate vehicle. In this sense, the vehicle procurement represents a significant activity for increasing the vehicle fleets energy efficiency. During a process of decision making in order to purchase an appropriate vehicle, managers take into consideration a number of different criteria. Based on the literature review, as well as on the basis of the author's own experience, the relevant criteria that have the significance on making the observed decision are defined in the paper. It is shown how the defined vehicle procurement criteria affect the increasing of vehicle fleet energy efficiency, as well as the reduction of the transport and maintenance costs. In order to make the right decision when purchasing a vehicle, managers need to take into consideration all defined criteria. This contributes to increasing of the vehicle fleet energy efficiency and reducing transportation and maintenance costs, thereby generating greater profit in the observed companies.
