Effective Notch Stress Concept Investigations for Mode-III Loading & Response Conditions

Fatigue strength is typically a governing limit state for marine structures. Predicting an accurate fatigue lifetime is important for structures (e.g. wind turbines) that are supposed to be out at sea for decades. It is valuable for all type of structures that encounter stochastic sea loadings to optimise the design so that fatigue failure is...

Prediction of Vehicles' Trajectories based on Driver Behavior Models

As a component of Dutch Automatic Vehicle Initiative (DAVI) project, this study aims at improving highway driving safety of autonomous vehicle. It is observed that some misbehaved drivers do not use turn indicators forehead a lane change on highway. For a self-driving car in such situations, a lane change is potentially dangerous without an...

Steering controller identification and design for human-like overtaking

Assessment of Subjective Workload in Traffic Situations using Video Fragments

Mental workload is an important subject in traffic safety research, however workload measurements are expensive and time intensive. To this end a measurement method is developed which uses short video fragments of driving situations to the subject, after which they are asked about their perceived mental effort if they would be driving through...

An in-car route and parking strategy for event traffic towards the Amsterdam ArenA to improve throughput

Level of Service estimation with in-vehicle sensor floating car data

In the Smart In-Car project, in-vehicle signals obtained from the CAN (Controller Area Network) bus are collected along with the GPS position from 200 equipped vehicles. The main CAN bus signals in the available data set from the Smart In-Car project are: speedometer, brake usage, steering position, rpm, indicator usage and fuel consumption, but...

Freeway Work Zone Driving Behaviour: The Influence of Work Zone Configurations

Problem definition and objective. The performance of work zones with specific layouts cannot be accurately determined, because changes in individual driving behaviour at work zones are unknown. Therefore, the research objective is: “Gain insight into possible adaptation effects related to the layout of work zones, in empirical individual driving...

Results of a field operational test of a context aware intelligent speed adaption system

In the past, several field studies have proven the technological feasibility of ISA-systems. Most of these studies used warning or assisting ISA-systems to influence drivers. Until now, studies that focused on a restricting (closed) method have only been executed on relatively small testing areas with slow speed zones. This report presents the...
