Due to increasing environmental concerns and energy prices, what is very important but has
not been given due consideration is the energy efficiency of metro rail systems. Train energy …

Both energy consumption and travel time are important indices to evaluate the efficiency of
operations of metro rail systems. This paper proposes an optimisation method to schedule …

Since the passenger demands change frequently in daily metro rail operations, the
headway, cycle time, timetable and speed profile for trains should be adjusted …

Energy‐efficient metro operation has received increasing attention because of the energy
cost and environmental concerns. This paper developed an integrated optimization model …

Due to rising energy prices and environmental concerns, the energy efficiency of urban rail
transit has attracted much attention from both researchers and practitioners in recent years …

In this paper we propose a novel two-step linear optimization model to calculate energy-
efficient timetables in metro railway networks. The resultant timetable minimizes the total …

Energy-efficient train operation is regarded as an effective way to reduce the operational
cost and carbon emissions in metro systems. Reduction of the traction energy and …

Regenerative braking is an energy recovery mechanism that converts the kinetic energy
during braking into electricity, also known as regenerative energy. In general, most of the …

This paper formulates a two-objective model to optimize the timetables of urban rail transit
systems based on energy-saving strategies and service quality levels. With time-dependent …

Increasing attention is being paid to the energy efficiency in metro systems to reduce the
operational cost and to advocate the sustainability of railway systems. Classical research …
