Highlights We estimate a set of regression models to examine fuel consumption in a bus company. Fuel consumption was measured for vehicles, drivers and routes. As expected, fuel consumption is highly dependent on vehicle type. Commercial speed is the second most influential variable. Training practices have an impact on the energy efficiency of bus operator companies.

    Abstract Energy costs account for an important share of the total costs of urban and suburban bus operators. The purpose of this paper is to expand empirical research on bus transit operation costs and identify the key factors that influence bus energy efficiency of the overall bus fleet of one operator and aid to the management of its resources. We estimate a set of multivariate regression models, using cross-section dataset of 488 bus drivers operating over 92days in 2010, in 87 routes with different bus typologies, of a transit company operating in the Lisbon’s Metropolitan Area (LMA), Rodoviária de Lisboa, S.A. Our results confirm the existence of influential variables regarding energy efficiency and these are mainly: vehicle type, commercial speed, road grades over 5% and bus routes; and to a lesser extent driving events such as: sudden longitudinal decelerations and excessive engine rotation. The methodology proved to be useful for the bus operator as a decision-support tool for efficiency optimization purpose at the company level.
