Abstract
Current sustainable policies, adopted by most of the world’s governments, have shown the necessity to promote the use of public transportation systems which provide lower external costs (such as congestion, accidents, air and noise pollution) compared to road transportation systems. In this context, the rail and metro systems allow to achieve further two objectives: the increase in efficiency (i.e. operational costs for real/potential carried passengers) and the delocalization of energy production centres (i.e. large industrial plants out of population centres). The above-mentioned positive aspects may be further increased by applying suitable energy-saving and energy-recovery strategies, generally based on the on the adoption of suitable driving profiles and/or installation of on-board/lineside storage devices. In this context, our proposal is based on the investigation of the effects of rolling-stock failures (for breakdowns, maintenance or under-sized fleet) on the effectiveness of energy-saving/energy-recovery measures within a multi-objective framework which combines the reduction in energy consumption with a passenger-oriented perspective. A regional rail line in the south of Italy has been analysed as case-study in order to show the feasibility of the proposed approach.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
