A Method for Determining How Much Time People Need to Understand Traffic Situations

It is expected that in the coming decade, cars with an automated driving mode will become available. Most likely, this automated mode will only be used in specific situations and/or on specific roads, which means that the driver/automation needs to switch between the automated mode and manual control. Such switches are termed ‘transitions of...

Adaptive Cruise Control in Practice: A Field Study and Questionnaire into its influence on Driver, Traffic Flows and Safety

Adaptive Cruise Control (ACC) is a system present which enables the car to autonomously maintain a certain speed, and based on the location and the speed of the predecessor, change the speed of the vehicle. This research is meant to determine the influence of ACC on the behavior of the driver, and on flows and safety on the road. Three databases...

Workload Assessment for Mental Arithmetic Tasks using the Task-Evoked Pupillary Response

Pupillometry is a promising method for assessing mental workload and could be helpful in the optimization of systems that involve human-computer interaction. The present study focuses on replicating the pupil diameter study by Ahern (1978) for mental multiplications of varying difficulty, using an automatic remote eye tracker. Our results showed...

Haptically Supporting Car Driving: Optimizing or Satisficing?

Abstract – Background: A principal design choice in providing steering wheel force feedback to assist drivers during lane-keeping is whether feedback should be provided for any error with respect to the lane centre (continuous feedback) or only when acceptable tolerance limits are exceeded (bandwidth feedback). Problem: Research has shown that...

Using a drinking water treatment simulator for operator training: Accelerating the simulated process leads to an increase in learning

The drinking water treatment industry is becoming increasingly centralized and automated. This requires a different operator training approach then the traditional on the job training. To address this requirement a drinking water treatment plant simulator was developed. A major advantage of such a simulator might be that the normally very slow...

A method for modelling operator behaviour applied to the NewTranspall microworld

Violation of safety procedures by operators is an important cause of accidents. To prevent violations effectively a thorough understanding of the operators' decision making process is required. This research proposes a method to create a personal model that predicts the action the operator would take based on the state of the system. We strive...

Decision making based on proactively collected event data for operating room management

Surgical processes place a heavy burden upon the finance of hospitals and should therefor be utilized effectively. Effectively, means (economically) efficient, safe for patients and personnel, and reliable for any actors (normal practice can be assumed). Rapid organizational learning is required to identify system vulnerabilities quickly and to...
