ESTABLISHMENT OF A MACROSCOPIC ESTIMATION EQUATION FOR ACTUAL FUEL CONSUMPTION OF PETROL-FUELLED PASSENGER VEHICLES

Abstract

This article aims at establishing a macroscopic equation for estimating fuel consumption of petrol-fuelled passenger vehicles by conducting multiple regression analysis. Fuel consumption figure from the actual fuel consumption database with hierarchic structure, which is based upon voluntary reported fuel consumption log data collected through the internet-connected mobile-phone system all over Japan, is adopted for dependent variable. Specifications of vehicles and macroscopic statistical indicators in which geographical and social characteristics are reflected are chosen for explanatory variables.
