Excited to share our latest publication in IEEE Access on Real-Time Railway Traffic Management! Our paper addresses the challenges of adjusting train timetables during perturbations to minimize delays and ensure seamless passenger connections. Abstract: This paper addresses the real-time Railway Traffic Management Problem (rtRTMP), which involves adjusting train timetables during perturbations. Perturbations in railway networks often lead to significant delays, necessitating strategies to minimize their propagation. An important objective of traffic management is to facilitate passenger transfers through connecting trains, which may become difficult when traffic is disturbed. Pursuing this objective, the paper focuses on mitigating train delays by reducing connection times during transfers without compromising connections. To achieve this, we extend an existing Mixed-Integer Linear Programming (MILP) formulation for the rtRTMP by introducing two alternative enhancements. Moreover, we pursue the same delay mitigation by extending an Ant Colony Optimization algorithm for the Train Routing Selection Problem (TRSP): this problem reduces the number of alternative routes to be considered for trains, making rtRTMP instances tractable. We assess the efficiency of the proposed enhancements in reducing the total train delay while preserving passenger connections in multiple instances representing traffic in the Lille-Flandres station control area, located in the north of France. The results demonstrate that the integration of these enhancements, in both the TRSP and the rtRTMP, results in a significant reduction in delay propagation.

Shaping ETCS for the future of railway Signalling - ETCS Hybrid train detection

🔸 Something I think we can all relate to is when you can't physically see a technology, it can be easy to forget it's even there. But that doesn't mean it isn't important. 🔸 5G for rail communications is precisely one of these 'invisible' technologies that most people won't necessarily be aware of but is incredibly vital to improving rail safety, passenger experience and even sustainability. 🚆 With rail companies on the verge of a major technological shift from GSM-R to the Future Radio Mobile Communication System (FRMCS) standard, it's never been more clear how 5G can truly revolutionize train operations. 📶 The question is, how will companies be able to implement their future proofed FRMCS cost-effectively? 🤔 This article from the International Railway Journal explores the key concepts for the efficient deployment of FRMCS in depth — well worth a read if you're curious like I am: https://lnkd.in/du3sd77r 👉 Ericsson 👉 UIC - International union of railways #UICrail #️⃣ #Ericsson #FRMCS #UIC #5GRailways #UICConference #FutureofRail #5G #Technology #Innovation #RailRevolution #Railway #TeamEricsson
