Abstract

A baseline in fuel economy is the indicator from which to start to evaluate consumption and raise awareness of the current state. Since what is not measured cannot be improved, the determination of a baseline helps to locate a starting point to establish further goals and best practices based on actual behavior. This paper explores and reviews the studies for fuel economy to determine the measurement and analysis methods that aim to the construction of fuel consumption and/or gas emission baselines by conducting a systematic literature review (SLR). The overview of literature published globally in the last ten years shows hardly any research focused on HDVs, as well as few investigations reporting gross and load weight values. Studies committed to measuring fuel consumption and/or gas emissions show small sample sizes due to limitations in scope related to the methods used, explaining the tendency to make estimates through statistical and estimation tools. Furthermore, it is important to emphasize that by abounding in the methods and the literature itself, the recent interest in expanding the sample sizes in line with the precision of the data, has presented new techniques for the measurement and estimation.
