Semi-automated versus highly automated driving in critical situations caused by...

The purpose of this study was to examine the effects of vehicle automation and automation failures on driving performance. Previous studies have revealed problems with driving performance in situations with automation failures and attributed this to...

End-users’ Acceptance and Use of Adaptive Cruise Control Systems

An online survey was distributed to end-users of adaptive cruise control (ACC). In total 90 drivers answered the questionnaire, which covered e.g. ACC usage and how such use affects driver behaviour. According the responses: the ACC is used...

How Is Acceptance Measured?

This chapter describes how acceptance has been measured and identifies various measurement categories. The relationship between these measurement methods and the different definitions of acceptance appearing in the literature is described and the...

Modelling Acceptance of Driver Assistance Systems

This chapter provides a brief overview of acceptance models used within the area of information technology.  One particular model, the Unified Theory of Acceptance and Use of Technology (UTAUT), is then discussed, and a study is reported in which...

The Definition of Acceptance and Acceptability

Despite the recognised importance of the concept of acceptance, how and why new technologies are actually accepted by drivers is not well understood. While many studies claim to have measured acceptance, few have explicitly defined what it is. This...

Dangerous use of mobile phones and other communication devices while driving

The use of mobile phone and similar devices while driving has been a topic of discussion and research for several years. It is now an established fact that driving performance is deteriorated due to distraction but no clear conclusions can yet be...

Driving simulation cooperation strategy

Körsimulering är ett omfattande och verkligt tvärvetenskapligt forskningsområde. Området innefattar bland annat visualisering, fordonsdynamik, ’motion cueing’, ljudåtergivning. Körsimulatorer används i forskningen inom alla delar av...

Åtgärder mot trafikfarlig användning av kommunikationsutrustning under körning

Rapporten kan ses som en verktygslåda av åtgärder med syfte att motverka de trafikfarliga aspekterna av kommunikation under körning och samtidigt bevara de positiva effekterna. Åtgärdsförslagen täcker flera områden och är tänkta som alternativ till...

Countermeasures against dangerous use of communication devices while driving –

Denna rapport behandlar tänkbara åtgärder för att reducera farligt användande av mobiltelefon och annan kommunikationsutrustning under körning. En viktig del i uppdraget var att belysa alternativ till lagstiftning om förbud. Åtgärdsförslagen täcker...

Tema miljörisker

This report compiles the results from the project Theme Environmental risks. More specifically, the project concerned how different transport related environmental risks influence different road users and how their behaviour influence the...

Exploring end-user experiences

This study explores end-user experiences of adaptive cruise control (ACC) systems. A qualitative approach has been applied and data have been collected by means of focus group interviews. A qualitative content analysis was carried out to analyse and...

Field test on visibility at cycle crossings at night

Denna rapport utgör dokumentation av en fältstudie som är en del i projektet "Trafikantstöd i mörkertrafik".De första delarna i projektet var en litteraturstudie om mörkertrafik i tätort samt en fokusgruppsstudiedär olika trafikantgruppers behov och...

Effects of cognitive and visual load in real and simulated driving

A simulator and a field experiment were conducted to study the effects of visual and cognitive load on driving performance, and also to assess the validity on the VTI simulator as a tool for studying the effects of distraction. It was found that...

Mobile telephone simulator study

The study consists of four separate experiments conducted in the VTI drivingsimulator. The common theme was to investigate how driver behaviour andtraffic safety are influenced when the driver attends to another technicaldevice while driving. The...

Traffic sense

A study was conducted to evaluate the skill to predict the development of traffic situations. A stop-controlled intersection was filmed over several days, and 12 scenes with varying traffic complexity were selected. In half of the scenes, the...

Utvärdering av kameraövervakade vägarbetsplatser

Att arbeta på och invid vägen är ett mycket utsatt arbete och mångavägarbetareupplever varje dag stor oro och otrygghet på jobbet. Problemet är högahastigheteroch alltför korta avstånd i kombination med ouppmärksamhet och bristande hän-syn hos...

Inhämtande av rörlig visuell information presenterad perifert i bilen

Syftet var att studera funktionen hos ett informationssystem som enbart använder sig av visuell information, presenterad perifert i synfältet med hjälp av ”rinnande ljus” i bilen. Informationen presenterades på displayer i fyra olika positioner;...
