POSADA HENAO, John Jairo  e  GONZALEZ-CALDERON, Carlos A.. FUEL CONSUMPTION IN VEHICLES FOR HIGHWAY TRANSPORTATION - PREDICTIVE MODELS. Rev. ing. univ. Medellín [online]. 2013, vol.12, n.23, pp.35-46. ISSN 1692-3324.

This article deploys models intended for estimating fuel consumption in vehicles for highway transportation, based on literature specialized in this topic and vehicle operation costs which include the fuel needed for reaching vehicle locomotion. Fuel consumption has been associated to variables such as vehicle characteristics, transported load, and circulation highway, so fuel consumption is deemed as a variable component within the vehicle operation costs structure, accounting for 20% and 60% of such costs. For its quantification, there are direct and indirect methods which can be used which allow creating some prediction models which, with a certain degree of accuracy, may predict consumption for specific operation conditions of vehicles which should be adjusted to certain conditions of each site.

Palavras-chave : Fuel consumption; vehicle operation costs; prediction models; project evaluation.
