Hazard Identification of Hydrogen-Based Alternative Fuels Onboard Ships

Van Rheenen, E.S. (author), Scheffers, E.L. (author), Zwaginga, J.J. (author), Visser, K. (author)

It is essential to use alternative fuels if we are to reach the emission reduction targets set by the IMO. Hydrogen carriers are classified as zero-emission, while having a higher energy density (including packing factor) than pure hydrogen. They are often considered as safe alternative fuels. The exact definition of what safety entails is often...

Radiofrequency safety of high permittivity pads in MRI—Impact of insulation material

Brink, Wyger M. (author), Remis, R.F. (author), Webb, A. (author)

Purpose: High permittivity dielectric pads are known to be effective for tailoring the RF field and improving image quality in high field MRI. Despite a number of studies reporting benign specific absorption rate (SAR) effects, their “universal” safety remains an open concern. In this work, we evaluate the impact of the insulation material in...

Exploring the Influence of Signal Countdown Timers on Driver Behavior: An Analysis of Pedestrian–Vehicle Conflicts at Signalized Intersections

Sheykhfard, Abbas (author), Haghighi, Farshidreza (author), Papadimitriou, E. (author), Das, Subasish (author), van Gelder, P.H.A.J.M. (author)

Although signal countdown timers (SCTs) are likely to enhance efficiency at signalized intersections, there is little research on how they affect road users’ behavior. The present study explores factors associated with driver behavior through two approaches to examine how SCTs influence drivers’ actions toward pedestrians violating red lights....

Safety and Sustainable Development of Automated Driving in Mixed-Traffic Urban Areas—Considering Vulnerable Road Users and Network Efficiency

Pauwels, A.J. (author), Pourmohammadzia, N. (author), Schulte, F. (author)

Next to environmental aspects, establishing areas for safe and economically viable automated driving in mixed-traffic settings is one major challenge for sustainable development of Autonomous Vehicles (AVs). This work investigates safety in the interactions between AVs, human-driven vehicles, and vulnerable road users, including cyclists and...

‘Ladder’-based safety culture assessments inversely predict safety outcomes

Boskeljon-Horst, L. (author), Sillem, S. (author), Dekker, S.W.A. (author)

There is little empirical evidence on the predictive value of safety culture assessments (SCAs) in relation to how accident-prone an organisation might be. Recently, Antonsen not just demonstrated how a quantitative SCA mispredicted future safety outcomes, but actually showed an inverse relationship between the assessment and subsequent critical...

In this study we identify the differences in goal realisation when applying two conflicting paradigms regarding rule perception and management. We gathered more than 30 scenarios where goal conflicts were apparent in a military operational unit. We found that operators repetitively utilized certain routines in executing their tasks in an effort...
