Introducing a multivariate model for predicting driving performance: The role of driving anger and personal characteristics

Roidl, Ernst ; Siebert, Felix Wilhelm ; Oehl, Michael ; Höger, Rainer (2013-08-15)

Introduction: Maladaptive driving is an important source of self-inflicted accidents and this driving style could include high speeds, speeding violations, and poor lateral control of the vehicle. The literature suggests that certain groups of drivers, such as novice drivers, males, highly motivated drivers, and those who frequently experience anger in traffic, tend to exhibit more maladaptive ...

The influence of time headway on subjective driver states in adaptive cruise control

Siebert, Felix Wilhelm ; Oehl, Michael ; Pfister, Hans-Rüdiger (2014-06-04)

There is no agreement on the relation between driving parameters and drivers’ subjective states. A linear as well as a threshold relationship for different subjective variables and driving parameters has been put forward. In this study we investigate the relationship between time headway and the ratings of risk, task difficulty, effort, and comfort. Knowledge about this interrelation may advanc...

The exact determination of subjective risk and comfort thresholds in car following

Siebert, Felix Wilhelm ; Oehl, Michael ; Bersch, Florian ; Pfister, Hans-Rüdiger (2017-02-04)

In this study the location of vehicle to vehicle distance thresholds for self-reported subjective risk and comfort was researched. Participants were presented with ascending and descending time headway sequences in a driving simulator. This so called method of limits of ascending and descending stimuli (Gouy, Diels, Reed, Stevens, & Burnett, 2012) was refined to efficiently determine individual...

How speed and visibility influence preferred headway distances in highly automated driving

Siebert, Felix Wilhelm ; Wallis, Fares Lian (2019-07-06)

While the introduction of highly automated vehicles promises lower accident numbers, a main requirement for wide use of these vehicles will be the acceptance by drivers. In this study a crucial variable for the acceptance of highly automated vehicles, the vehicle to vehicle distance expressed in time headway, was researched in a driving simulator. Research has shown that time headway distances,...

Siebert, Felix Wilhelm ; Albers, Deike ; Naing, U Aung ; Perego, Paolo ; Santikarn, Chamaiparn (2019-01-11)

Developing countries are subject to increased motorization, particularly in the number of motorcycles. As helmet use is critical to the safety of motorcycle riders, the goal of this study was to identify observable patterns of helmet use, which allow a more accurate assessment of helmet use in developing countries. In a video based observation study, 124,784 motorcycle riders were observed at s...

The more the better? The impact of number of stages of likelihood alarm systems on human performance

Balaud, Magali ; Manzey, Dietrich (2015)

Responses to alarms involve decisions under uncertainty. Operators do not know if an alarm is more likely to be a hit or a false alarm. Likelihood alarm systems (LAS) help reduce this uncertainty by providing information about the certainty of their output. Unlike traditional binary alarm systems, they have three or more stages: each one represents a different degree of likelihood that a critic...

Decision-making and response strategies in interaction with alarms: the impact of alarm reliability, availability of alarm validity information and workload

Manzey, Dietrich ; Gérard, Nina ; Wiczorek, Rebecca (2014-09-16)

Responding to alarm systems which usually commit a number of false alarms and/or misses involves decision-making under uncertainty. Four laboratory experiments including a total of n=256 participants were conducted to gain comprehensive insight into humans’ dealing with this uncertainty. Specifically, it was investigated how responses to alarms/nonalarms are affected by the predictive validitie...

Do we really need more stages? Comparing the effects of likelihood alarm systems and binary alarm systems

Zirk, Anna ; Wiczorek, Rebecca ; Manzey, Dietrich (2019-06-19)

Objective: This research investigates the potential behavioral and performance benefits of a 4-stage likelihood alarm system (4-LAS) contrasting a 3-LAS, a binary alarm system with a liberal threshold (lib-BAS) and a BAS with a conservative threshold (con-BAS). Background: Prior research has shown performance benefits of 3-LASs over conventional lib-BASs due to more distinct response strategie...

Trust in highly automated driving

Stephan, Amelie (2019)

The automotive industry is on the verge of a new technology: self-driving vehicles. Such highly automated driving vehicles are more and more technically feasible, and corporations and research institutes all over the world are investing time and money to bring the once futuristic vision on the road. The technology is developed with the goal to release the driver from the manual task of controll...

Effects of Trust, Self-Confidence, and Feedback on the Use of Decision Automation

Wiczorek, Rebecca ; Meyer, Joachim (2019-03-12)

Operators often fail to rely sufficiently on alarm systems. This results in a joint human-machine (JHM) sensitivity below the one of the alarm system. The ‘confidence vs. trust hypothesis’ assumes the use of the system depends on the weighting of both values. In case of higher confidence, the task is performed manually, if trust is higher, the user relies on the system. Thus, insufficient relia...

On the Relation Between Reliance and Compliance in an Aided Visual Scanning Task

Wiczorek, Rebecca ; Meyer, Joachim ; Günzler, Torsten (2012)

Alarms, alerts, and other binary cues affect user behavior in complex ways. One relevant distinction is the suggestion that there are two different responses to alerts – compliance (the tendency to perform an action cued by the alert) and reliance (the tendency to refrain from actions as long as no alert is issued). An experiment tested the dependence of the two behaviors on the Positive and Ne...

Benefits of Decision-Support by Likelihood versus Binary Alarm Systems

Wiczorek, Rebecca ; Manzey, Dietrich ; Zirk, Anna (2014)

Recent research has shown that the use of 3-stage likelihood alarm systems (LAS) has the potential to mitigate performance deficits associated with the use of binary alarm systems (BAS). The additional likelihood information can guide operators’ behavior and improve their decision-making accuracy. Comparisons of LAS with different numbers of stages are missing so far. Therefore, the current stu...

Supporting Attention Allocation in Multitask Environments

Wiczorek, Rebecca ; Manzey, Dietrich (2014)

Objective: The aim of the current study was to investigate potential benefits of likelihood alarm systems (LASs) over binary alarm systems (BASs) in a multitask environment. Background: Several problems are associated with the use of BASs, because most of them generate high numbers of false alarms. Operators lose trust in the systems and ignore alarms or cross-check all of them when other info...

Is Operators' Compliance with Alarm Systems a Product of Rational Consideration?

Wiczorek, Rebecca ; Manzey, Dietrich (2010)

Most theories about operators' responses to alarm systems suggest that the operators' behavior is guided by their trust towards the system which in turn results from the subjective perception of system properties, namely the perceived reliability of the alarm system. However, some doubts about that assumption have arisen as recent research has not proven the mediating effect of trust. The purpo...
