Santana, Ricardo (author)Low-altitude, high-density air traffic is expected to grow in the coming decades with several companies being certified to initiate urban operations for both freight and passenger transport. However, traditional human-centered Air Traffic Control operations (ATCos) are not scalable to handle the increased demand to maintain safe separation...master thesis 2023

Zhang, Lei (author), Liu, Wenjie (author), Du, Zhe (author), Du, Lei (author), Li, Xiaobin (author)Collision avoidance is a priority task for ensuring the safety of a maritime transportation system. However, for a ship towing system, which is characterized by multiple vessels and physical connections, the research works about collision avoidance is limited. Thus, this paper proposes a speed and heading control-based conflict resolution of...journal article 2023

Badea, C. (author), Morfin Veytia, A. (author), Patrinopoulou, Niki (author), Daramouskas, Ioannis (author), Ellerbroek, Joost (author), Lappas, Vaios (author), Kostopoulos, Vassilios (author), Hoekstra, J.M. (author)The use of small aircraft for a wide range of missions in urban airspace is expected to increase in the future. In Europe, efforts have been invested into developing a unified system, called U-space, to manage aircraft in dense very-low-level urban airspace. The Metropolis II project aimed to research what degree of centralisation an air traffic...journal article 2023

de Jong, Arnoud (author)The impact of delays and disturbances in railway traffic can be mitigated by advanced rail traffic rescheduling models (RTRMs) which make use of mathematical optimization models. In the past several researches have been carried out on the effectiveness of an RTRM in reducing delay and improving punctuality. However, in most of these researches...master thesis 2022

Janssens, Mathilde (author)Railway networks are to play an increasingly large role in European transportation. This has boosted the urgency of railway innovations, of which the development of decision support systems for conflict resolution is an important aspect. This research contributes to this development by formulating a suitable mathematical approach for railway...master thesis 2022

Aarts, Michiel (author)The traffic density of small aerial vehicles operating within urban environments is expected to increase significantly in the near future. This urban environment is highly constrained due to being limited to the low-altitude airspace directly above the existing road network. To increase understanding of the factors influencing the capacity of...master thesis 2021

Aydoğan, Reyhan (author), Baarslag, T. (author), Gerding, Enrico (author)Conflict resolution is essential to obtain cooperation in many scenarios such as politics and business, as well as our day to day life. The importance of conflict resolution has driven research in many fields like anthropology, social science, psychology, mathematics, biology and, more recently, in artificial intelligence. Computer science...contribution to periodical 2021

Nasrulin, B. (author), Pouwelse, J.A. (author)Decentralized systems offer alternatives to Big Tech. However, maintaining availability and correctness despite faults and manipulations in decentralized settings is challenging. In this paper, we introduce a collaborative model that is capable of exposing all observable lying, all cheating, and all faults, while only requiring merely...conference paper 2021

Hoekstra, J.M. (author), Ellerbroek, J. (author)Purpose of Review A lot of research into decentralised, state-based conflict detection and resolution, or detect and avoid algorithms has been executed. This paper explains the essential properties of state-based conflict detection and reviews the work in the context of applications for not only manned but also unmanned aerial vehicles, where...journal article 2021

Schaberg, Wouter (author)In an effort to increase airspace capacity, new methods for the decentralization of air traffic control have been a topic for research since the early nineties. The Modified Voltage Potential is a method to provide decentralized conflict detection and resolution. Through this method, aircraft can fly direct routes while resolving conflicts in a...master thesis 2020

Huang, Y. (author), Chen, L. (author), Chen, P. (author), Negenborn, R.R. (author), van Gelder, P.H.A.J.M. (author)Collision prevention is critical for navigation safety at sea. At early ages, researchers aimed at developing navigational assistance systems for enhancing situational awareness of human operators as human is at the core of collision avoidance. Recently, autonomous vehicles have gained a remarkable amount of attention with a focus on solving...review 2020

Tegginamani Shiva Kumar, Siddarth (author)The Air Traffic Management research community expects that the responsibility of maintaining a minimum safe separation distance between aircraft will move from the groundbased Air Traffic Control, a centralized system, towards the flight deck, a decentralized system. Previous research on the decentralized, also known as distributed Air Traffic...master thesis 2018

Kayal, A. (author), Brinkman, W.P. (author), Neerincx, M.A. (author), van Riemsdijk, M.B. (author)Social commitments (SCs) provide a flexible, norm-based, governance structure for sharing and receiving data. However, users of data sharing applications can subscribe to multiple SCs, possibly producing opposing sharing and receiving requirements. We propose resolving such conflicts automatically through a conflict resolution model based on...journal article 2018

Balasooriyan, Suthes (author)Currently, Air Traffic Control is responsible for the separation of air traffic in our limited airspace. To facilitate the continuing growth of air traffic, an ambitious plan is to give the responsibility of the separation task to the pilots of the aircraft. The behavior of existing conflict resolution methods within this decentralized approach...master thesis 2017
