What is Energy Efficiency Optimization in Transport?
Energy Efficiency Optimization in Transport applies genetic algorithms, dynamic programming, and reinforcement learning to minimize energy consumption in mixed traffic scenarios, with focus on regenerative braking coordination and eco-routing.
This subtopic addresses energy loss detection in electric railway vehicles (Fischer and Kocsis Szürke, 2023, 62 citations) and traction energy consumption under speed restrictions (Fischer, 2015, 24 citations). Regenerative braking and smart grid technologies in public transport power systems are key areas (Bartłomiejczyk, 2018, 21 citations; Liudvinavičius and Povilas, 2011, 9 citations). Over 10 papers from the list highlight reliability modeling and maintenance impacts on energy use.
Why It Matters
Energy efficiency optimization reduces operational costs and supports decarbonization in rail and public transport systems. Fischer and Kocsis Szürke (2023) quantify energy losses in electric railway vehicles, enabling targeted regenerative braking improvements that recover braking energy. Bartłomiejczyk (2018) demonstrates smart grid integration in public transport, cutting electricity costs amid rising prices. These advances align with EU sustainability goals by minimizing fuel use in locomotives (Fischer, 2015; Liudvinavičius and Povilas, 2011).
Key Research Challenges
Detecting Hidden Energy Losses
Energy losses in electric railway vehicles are hard to detect due to complex interactions in hauling systems (Fischer and Kocsis Szürke, 2023, 62 citations). Hidden factors like multimodal empirical distributions complicate modeling (Kozłowski et al., 2023, 42 citations). Accurate detection requires advanced simulation under variable conditions.
Optimizing Regenerative Braking
Coordinating regenerative braking in mixed traffic demands precise energy return management amid speed restrictions (Fischer, 2015, 24 citations). Electrodynamic braking regulation faces challenges from diesel integration and external factors (Liudvinavičius and Povilas, 2011, 9 citations). Reliability in recovery systems remains inconsistent.
Integrating Smart Grids
Public transport power supply systems struggle with smart grid adoption for energy saving (Bartłomiejczyk, 2018, 21 citations). Reliability-exploitation modeling of telematics devices highlights vulnerabilities (Stawowy et al., 2021, 27 citations). Variable operating conditions degrade functional reliability.
