Abstract

EBSF_2 is a research project led by the International Association of Public Transport and funded by the"br" European Union with the aim of increasing attractiveness and efficiency of urban bus systems. EBSF_2"br" combines experiments with research as it relies on demonstrators, i.e. innovative technologies are tested on"br" vehicles operating in 12 European bus networks and evaluated through a methodology to assess the soundness of"br" the innovations and their affordability. The innovations under test are different, but increased energy efficiency"br" is the goal for several test sites which are working to: a) advance energy management of buses, b) lower the"br" energy needed for on-board heating, ventilating and cooling; c) develop energy-efficient driver support systems."br" The paper describes how the topic energy efficiency is addressed within the EBSF_2 demonstrators. The"br" assessment methodology designed to measure the performance variations in each demonstrator and cross-case is"br" presented, together with the testing scenarios for three demonstrators and the preliminary results achieved.
