In the driver's mind: cognitive modeling of human overtaking behavior when interacting with oncoming automated vehicles

Understanding human behavior in overtaking scenarios is crucial for enhancing road safety in mixed traffic with automated vehicles (AVs). Modeling plays a pivotal role in advancing our comprehension of human overtaking behavior in dynamically evolving scenarios. Currently, our understanding of overtaking behavior primarily revolves around...

Interactive Merging Behavior in a Coupled Driving Simulator: Experimental Framework and Case Study

Human highway-merging behavior is an important aspect when developing autonomous vehicles (AVs) that can safely and successfully interact with other road users. To design safe and acceptable human-AV interactions, the underlying mechanisms in human-human interactive behavior need to be understood. Exposing and understanding these mechanisms can...

Stated choices and simulated experiences: Differences in the value of travel time and reliability

Surveys with stated choice experiments (SCE) are widely used to derive values of time and reliability for transport project appraisal purposes. However, such methods ask respondents to make hypothetical choices, which in turn could create a bias between choices made in the experiment compared to those in an environment where the choices have...

Lane Trace Assist: A methodology for supported steering feel evaluation and optimization

The modern era is witnessing a crucial revolution regarding the driving concept, towards a more assisted and automated way of driving. Despite the advantages such conception have been extensively predicted and supported in literature, a direct transition from manual to fully automated operation is at the current moment not feasible, both for...

Blind driving by means of the track angle error

This study is the third iteration in a series of studies aimed to develop a system that allows driving blindfolded. We used a sonification approach, where the predicted angular error of the car 2 seconds into the future was translated into spatialized beeping sounds. In a driving simulator experiment, we tested with 20 participants whether a...

Driver Behaviour during Control Transitions between Adaptive Cruise Control and Manual Driving: Empirics and Models

Adaptive Cruise Control (ACC) and automated vehicles can contribute to reduce traffic congestion and accidents. Field operational Tests have shown that drivers may prefer to deactivate ACC systems that are inactive at low speeds in dense traffic conditions and before changing lanes. These transitions between automated and manual driving are...

Driver behaviour near the vehicle handling limits in vehicles with an extended linear handling region

Lateral acceleration is a key aspect of the vehicle response perceived by the driver. Assistance systems such as Active Rear Steering (ARS) or Torque Vectoring (TV) are developed to modify the lateral acceleration response such that the vehicle has an improved stability and an extended linear handling region. With this extended linear handling...

Object Tracking in Images of an Airborne Wide Angle FMCW Radar

Object tracking is performed when surveillance applications have multiple observations of an object over time. An example of such a surveillance application is mounting a wideangle Frequency Modulated Continuous Wave (FMCW) radar system on board of a General Aviation aircraft. This is done in order to observe its environment in detail, including...

New Data Sources in Road Infrastructure Management: A game-based experiment into the effects of new data sources on condition assessment and decision-making within the operations and maintenance phase of asphalt paved road infrastructures

Professionals in the Operations and Maintenance phase of national road <br/>infrastructure projects are making decisions with large consequences based on low frequency measurements and subjectivity prone expert observations. A solution is expected in sensor innovations, IoT and User Generated Data to generate more frequent measurements and less...

The road safety of merging tapers: Measuring the effect of varying geometric designs and traffic conditions on driving behaviour at merging tapers

In Dutch design guidelines it is presumed that merging tapers are unsafe compared to the standard merger design. However, this presumption is not scientifically underpinned and therefore it is unclear whether this presumption is correct and if merging tapers are indeed unsafe. Design guidelines for merging tapers are neither scientifically...

Effects of task complexity and time pressure on activity-travel choices: Heteroscedastic logit model and activity-travel simulator experiment

This paper derives, estimates and applies a discrete choice model of activity-travel behaviour that accommodates potential effects of task complexity and time pressure on decision-making. To the best of our knowledge, this is the first time that both factors (task complexity and time pressure) are jointly captured in a discrete choice model....

Car following model of the distracted driver

Driving a car is common but complex everyday task. Nowadays the mobile phone, infotainment and navigation systems are used while driving. These distract the driver from their driving task. What is the implication on driving safety? How is the car following behaviour influenced by distraction? Can this be described by a car following model? The...

The Effects of Information and Communication Technologies on Accessibility

It is expected that information and communication technology (ICT) can have great impacts on traveler’s accessibility. However, understanding of the effects of ICT on accessibility is still limited. Consequently, this thesis aims to increase the understanding of such effects. The thesis develops a generic formal integrative behavioral model to...

Empirical longitudinal driving behaviour in case of authority transitions between adaptive cruise control and manual driving

Automated vehicles are expected to have a substantial impact on traffic flow efficiency, safety levels and levels of emissions. However, Fields Operational Tests suggest that drivers may prefer to disengage Adaptive Cruise Control (ACC) and resume manual control in dense traffic conditions and before performing manoeuvres such as lane changing....
