Mitigating Regional Traffic Congestion via School Start Time Scheduling: A Bilevel Alternating Optimization Approach
Antonios Georgantas, Stelios Timotheou, Christos G. Panayiotou
This paper addresses morning commute congestion caused by concentrated school-related trips in urban networks. We propose a bi-level optimization framework for regulating school st…
Multi-Regional Traffic Control with Travel and Charging Demand Co-Management
Yixun Wen, Stelios Timotheou, Boli Chen
Urban traffic management is essential for reducing congestion and supporting sustainable mobility. However, the task is becoming more challenging due to the growing penetration of…
Stability of vehicular admission control schemes in urban traffic networks under modelling uncertainty
Michalis Ramp, Andreas Kasis, Stelios Timotheou
Urban transportation networks face significant challenges due to traffic congestion, leading to adverse environmental and socioeconomic impacts. Vehicular admission control (VAC) s…
On the stability properties of power networks with time-varying inertia
Andreas Kasis, Stelios Timotheou, Marios Polycarpou
A major transition in modern power systems is the replacement of conventional generation units with renewable sources of energy. The latter results in lower rotational inertia whic…
Energy Consumption Optimization for Autonomous Vehicles via Positive Control Input Minimization
Andreas Hadjigeorgiou, Stelios Timotheou
Autonomous vehicles (AVs) present a unique opportunity to improve the sustainability of transportation systems by adopting eco-driving strategies that reduce energy consumption and…
