Abstract
Fuel consumption (FC) is a one component of the vehicle operation costs (VOC). The FC depends on many indicators that can be sorted in to following groups: vehicle-related indicators, road-related indicators, traffic-related indicators, weather-related indicators, driver-related indicators. There’s many others indicators with minor influence on FC that not belonging to this five groups of indicators. This paper will review a literature related to all fuel consumption groups of indicators. Special attention will be on road related indicators. The road related and traffic-related Fuel Consumption models have been widely used primarily in Cost Benefit Analysis (CBA) for road projects evaluation. The road related indicators can be divided in to technical (grade, curvature, horizontal and vertical curves etc.) and exploitation (pavement condition and others). To address these issues, a systematic review of fuel consumption models and the factors that influence fuel economy is presented. The limitations and possibilities of fuel consumption modelling, as well as possibility of application in engineering are highlighted in conclusion of paper.
