Abstract
In railway systems, the evaluation of specific operating conditions and their
impact on travel demand plays a key role both in planning and managing rail
services. In this paper, we focus on the implementation of some energy saving
strategies (ESSs) through the definition of energy-efficient speed profiles and
estimate their effects on travel demand. In particular, speed profiles for ESSs
need extra time for their implementation and hence entail a reduction in line
performance. The definition of optimal speed profiles requires the use of
optimisation procedures which can be formulated by considering motion
parameters as control variables and energy consumption as the performance to be
optimised (minimised), with respect to the available time. The proposed
methodology is applied in the case of a real metro line, showing differences in
user generalised costs, in order to provide additional information for rail
operators which may allow evaluation of the best strategies to be adopted.
Keywords: energy saving strategies, user generalised costs, rail passenger
systems, public transport management.
