Landslide activity in the Andes remains an ongoing natural hazard with significant implications for regional development. Slow-moving landslides, while not typically resulting in catastrophic outcomes, can still cause substantial damage to critical infrastructure, including roads, buildings, crops, and hydropower dams. In southeast Ecuador, slow...

Future Mars exploration missions require safe and controlled landing on the planet’s surface. Conventional entry, descent and landing (EDL) technologies, such as parachutes and rigid aeroshells, face limitations in meeting increasing demands for heavier payloads, harsher entry conditions, and desired landing locations due to their limited...

Although much research is done on speed and gaze behaviour inside curves, there is little understanding of which cues drivers use to anticipate and slow down while approaching curves. Therefore, an on road experiment was conducted in which 31 participants drove through six freeway curves in their own car. During the experiment, look-ahead...

The reason for this choice of topic is a life-long bewilderment towards the self-destructive potential of humankind. Supposed continuous accumulation of value is nurturing some of the most destructive and unvaluable events that this globe has ever seen. In many cases, the driver for what we do - our idea of what is valuable - seems to be leading...

Slow-moving landslides move downslope at velocities that range from mm year<sup>−1</sup> to m year<sup>−1</sup>. Such deformations can be measured using satellite-based synthetic aperture radar interferometry (InSAR). We developed a new method to systematically detect and quantify accelerations and decelerations of slowly deforming areas...

An important question in the development of automated vehicles (AVs) is which driving style AVs should adopt and how other road users perceive them. The current study aimed to determine which AV behaviours contribute to pedestrians' judgements as to whether the vehicle is driving manually or automatically as well as judgements of likeability....

This research investigates the speed behaviour and safety effects on cyclists and mopeds sharing the cyclist T-Intersection with and without the application of a lane marking nudge. Unsignalised cyclist T-Intersection gives rise to more safety-critical instances, which include unsafe braking and evasive maneuvers. It is also found that...

Grincell, Thomas (author)
This MSc thesis research has the objective to empirically determine the perceived stochastic nature of the deceleration regimes and to determine the impact it has on infrastructure occupation within the network corridor. This research expands on the data-driven reconstruction model to estimate the speed profiles of realised train runs developed...

Measuring risk is critical for collision avoidance. The paper aims to develop an online risk level classification algorithm for forward collision avoidance systems. Assuming risk levels are reflected by braking profiles, deceleration curves from critical evasive braking events from the Virginia “100-car” database were first extracted. The...

It is commonly accepted that vision plays an important role in car braking, but it is unknown how people brake in the absence of visual information. In this simulator study, we measured drivers’ braking behaviour while they had to stop their car at designated positions on the road. The access to visual information was manipulated by occluding...

This paper presents the results of an experimental study on stone stability under nonuniform turbulent flow, in particular expanding flow. Detailed measurements of both flow and turbulence and the bed stability are described. Than various manners of quantifying the hydraulic loads exerted on the stones on a bed are extensively reviewed and...

The thesis describes the algorithms design required to perform in-trail self-spacing during continuous descent approaches. Both distance-based and time-based spacing is treated. The CDA-procedure that is investigated is the Three-Degree Decelerating Approach (TDDA). The results of various off-line and simulator experiments as well as test flight...

Despite the fact that many studies on the stability of stones in bed protections under flowing water have been conducted, our knowledge is still far from advanced and reliable. Issues like how to quantify the hydraulic loads exerted on the stones on a bed and the associated stability of the stones are still central and most challenging in stone...

The current research is aimed at evaluating the applicability of a numerical flow model to predict bed damage. First, an experimental study was carried out to get more inside into the relation between flow forces acting on a bed and the bed response (damage). The experiments were then used as the basis for the evaluation. Second, the flow was...

The velocity and turbulence distributions of decelerating open-channel flow in a gradual expansion were measured using LDV equipment. The results show that the logarithmic law can describe the mean velocity in the bottom region well while the Coles’ law can be applied to the outer region. The shear velocity can be determined both by the...

The current research is aimed at finding a proper relation between flow forces acting on the bed and the bed response. To this end, experiments were carried out in which both the bed response (quantified by a dimensionless entrainment rate) and the flow field (velocity and turbulence intensity distributions) are measured. The three available...

Aircraft noise perceived on the ground can be reduced by decelerating the aircraft during the landing approach. As an additional benefit the lower thrust settings existing during a part of the approach and the shorter approach time result in a reduced fuel consumption as compared to a conventional approach. This report deals with an experiment...
