Singleton, Patrick A. (author), De Vos, Jonas (author), Heinen, Eva (author), Pudane, B. (author)Transportation's effects on health and well-being are widely recognized. In the near future, autonomous vehicles (AVs) are expected to revolutionize transportation options and ways of travel. Consequently, the effect of AVs on population health and well-being is a crucial topic of interest for transportation policymaking, one that has...book chapter 2020

van Wee, G.P. (author)Cycling is increasingly receiving attention in research and policy and practice, in many cities and regions in the world. The focus is mainly on cycling infrastructure and effects on travel behavior and health. The economics of cycling have not received a lot of attention yet. This chapter gives an overview of the current state of knowledge...book chapter 2021

Blokland, P.J. (author), Reniers, G.L.L.M.E. (author)When discussing the concepts of risk, safety, and security, people have an intuitive understanding of what these concepts mean and to a certain level, this understanding is universal. However, when delving into the meaning of the words and concepts in order to fully understand all their aspects, one is likely to fall into a semantic debate...book chapter 2020

van Adrichem, R.C. (author), Jovanova, J. (author)As machines and robots become a increasingly larger part of society, it is important that they are fully accepted. If the machines are not utilized as intended, it is not only a waste of time and energy, but also of valuable resources. This acceptance by humans of robots is based on how well the interaction with robots is trusted. Trust of...conference paper 2021

Kiel, Jan (author), Taale, Henk (author)In Europe, different road authorities have to face the ever increasing pressure to integrate their road network service provision with - often conflicting - different trends and conditions such as congestion, climate change, individualism, urbanization, safety, environmental issues and economic growth. There is also a need to cooperate with...conference paper 2019

Hoekstra, J.M. (author), Maas, J.B. (author), Tra, M.A.P. (author), Sunil, E. (author)In many ATM studies experiments are performed to determine the capacity. This paper looks at the effect of airspace design on the capacity. Using an algebraic approach a relation is derived between the design parameters of a layered airspace design and the capacity of the airspace. The validity of the assumptions which are used in this...conference paper 2016

Liebenwein, Lucas (author), Schwarting, Wilko (author), Vasile, Cristian-Ioan (author), DeCastro, Jonathan (author), Alonso-Mora, J. (author), Karaman, Sertac (author), Rus, Daniela (author)Recent advances in autonomous driving have raised the problem of safety<br/>to the forefront and incentivized research into establishing safety guarantees. In this paper, we propose a safety verification framework as a safety standard for driving controllers with full or shared autonomy based on compositional and contract-based principles. Our...conference paper 2017

Freese, M. (author), van Vliet, Karen (author)Organizations will go through great lengths to prevent accidents from occurring. This is shown in the implementation of safety management systems in which all procedures are captured describing how work can be done safely. Stopping the work is seen as one of the last barriers in risk management. Our theoretical analyses and conducted interviews...conference paper 2023

Chockalingam, S. (author), Pieters, W. (author), Teixeira, Andre M. H. (author), Khakzad, N. (author), van Gelder, P.H.A.J.M. (author)Because of modern societies' dependence on industrial control systems, adequate response to system failures is essential. In order to take appropriate measures, it is crucial for operators to be able to distinguish between intentional attacks and accidental technical failures. However, adequate decision support for this matter is lacking. In...conference paper 2019

Langejan, T.P. (author), Sunil, E. (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)Most Free-Flight concepts rely on self-separation by means of airborne Conflict Detection and Resolution (CD&R) algorithms. A key enabling technology for airborne CD&R is the Automatic Dependent Surveillance-Broadcast (ADS-B) system, which is used for direct state information exchange between aircraft. Similar to other communication...conference paper 2016

Zhang, Xinglong (author), Peng, Yaoqian (author), Pan, W. (author), Xu, Xin (author), Xie, Haibin (author)Distributed model predictive control (DMPC) concerns how to online control multiple robotic systems with constraints effectively. However, the nonlinearity, nonconvexity, and strong interconnections of dynamic system models and constraints can make the real-time and real-world DMPC implementations nontrivial.

Metz, I.C. (author), Mühlhausen, Thorsten (author), Ellerbroek, Joost (author), Kügler, Dirk (author), Hoekstra, J.M. (author)This paper presents a collision avoidance algorithm to prevent bird strikes for aircraft departing from an airport. By using trajectory-information of aircraft and birds, the algorithm predicts potential collisions. Collision avoidance is performed by delaying departing aircraft until they can follow a collision-free trajectory. An...conference paper 2019
