Abstract [en]

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 primarily on roads with higher speed limits; the end-users trust the system even though it has some functional limitations; they have a very positive attitude towards the system; and positive effects on comfort and safety are observed including reduced inclination to overtake and increased compliance with speed regulations.

Abstract [en]

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 lack of correspondence between definition and measurement is highlighted. The chapter illustrates the different outcomes of acceptance measurements depending on choice of assessment method and gives some guidance that could be used depending on the purpose of the assessment.

Abstract [en]

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 model was used to assess driver acceptance of a particular driver assistance system. The key findings of that study are reported, and suggestions are made for refining UTAUT to make it more suitable for assessing acceptance of driver assistance systems.

Abstract [en]

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 drivers being out-of-the-loop. It was therefore hypothesized that driving performance is safer with lower than with higher levels of automation. Furthermore, it was hypothesized that driving performance would be affected by the extent of the automation failure. A moving base driving simulator was used. The design contained semi-automated and highly automated driving combined with complete, severe, and moderate deceleration failures. In total the study involved 36 participants. The results indicate that driving performance degrades when the level of automation increases. Furthermore, it is indicated that car drivers are worse at handling complete than partial deceleration failures.

Abstract [en]

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 chapter points out the importance of defining acceptance and categorises definitions that have been used according to their “essence”. Distinctions between different types of acceptance as well as between acceptance and acceptability are also described. A proposal for a common definition of acceptance is then presented and discussed.

Abstract [en]

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 drawn concerning influence on crash rates. Better studies on this relationship is needed. Most countries in Europe and many countries elsewhere have introduced different types of bans for handheld devices. Sweden has, however, no such bans. VTI was commissioned by the Swedish Government to outline possible means to reduce the dangerous usage of mobile phones and other communication devices while driving as alternatives to banning. This task was a result of a previous VTI-state-of-the-art review of research on mobile phone and other communication device usage while driving. One of the findings in the review was that bans on handheld phones did not appear to reduce the number of crashes.

Eighteen different countermeasures in three main areas were suggested. (1) Technical solutions such as countermeasures directed towards the infrastructure, the vehicle and the communication device. (2) Education and information, describing different ways to increase knowledge and understanding among stakeholders and different driver categories. (3) Different possibilities for how society, industry and organisations can influence the behaviour of individuals, via policies, rules, recommendations and incentives. Our conclusion is that a combination of different countermeasures is needed – where education and information to the drivers are combined with support and incentives for a safe usage of different communication devices.

Abstract [sv]

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 flera områden. Ett av dem är teknik, vilket innefattar både teknik i fordonet, teknik i kommunikationsutrustningen och en sammankoppling med infrastrukturen. Ett annat område handlar om utbildning och information och beskriver olika sätt att öka människans kunskap och förståelse. Ett tredje område belyser olika möjligheter som samhället har att påverka människans beteende, både via förbud och lagar och via incitament. En lista över samtliga åtgärdsförslag finns på rapportens baksida. Det finns både för- och nackdelar med användandet av kommunikationsutrustning under körning. Hur användandet ska hanteras är ett komplext problem och det är osannolikt att en enskild åtgärd står för hela lösningen. En åtgärd kan till och med vara beroende av att andra åtgärder redan är implementerade. Många åtgärder har en baksida och man kan inte förvänta sig tydliga målbilder och rakt igenom positiva resultat. Man måste därför lyfta blicken och inse att om fördelarna överväger nackdelarna så är åtgärden värd att genomföra. Olika åtgärder kan dock stärka varandra och delvis fånga upp möjliga negativa sidoeffekter. Vi anser att en kombination av olika åtgärder som dels utbildar och informerar och dels stöttar föraren i att kunna hantera kommunikation på ett säkert sätt är att föredra över ett förbud av användningen av kommunikationsutrustning under färd likt det som idag finns i andra europeiska länder. En kontinuerlig uppföljning och utvärdering krävs för att säkerställa att åtgärderna har förväntad effekt.

Abstract [en]

This report outlines possible means to reduce the dangerous usage of mobile phones and other communication devices while driving. An important aspect of this commission was to demonstrate alternatives to legislation. The suggested countermeasures cover several areas. One is technical solutions, including countermeasures directed towards the infrastructure, the vehicle and the communication device. Another area includes education and information and describes different ways to increase knowledge and understanding. Furthermore, there are different possibilities for how society can influence the behaviour of individuals, both via bans, recommendations and incentives. The usage of communication devices while driving has both advantages and disadvantages. How to deal with device usage is a complex problem, and it is unlikely that one single countermeasure can provide a complete solution. One countermeasure may even depend on the implementation of others. The exact effect of most countermeasures is hard to predict, and possible side effects may occur. It is therefore necessary to be pragmatic, meaning that countermeasures whose advantages outweigh their disadvantages should be implemented. Also, different countermeasures can reinforce each other which may attenuate negative side effects. It is our opinion that a combination of different countermeasures – which educate and inform the driver while at the same time support him or her in a safe usage of communication devices – is preferable to a law against communication device usage while driving. Continuous follow-ups are necessary to ensure the outcome of implemented countermeasures.

Abstract [sv]

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 transportområdet, från väg-, infrastuktur- och fordonsutformning till förarbeteende och human factors. Andra viktiga områden som använder sig av körsimulering, förutom forskningen, är till exempel produktutveckling, träning och utbildning, demonstration och visualisering, racerbilsinställning och speltillämpningar. Den rapporterade förstudien har genomförts på uppdrag av Chalmers. Studien har fokuserat på hur man bygger och vidmakthåller kompetens och kunskap inom körsimuleringsområdet, samt hur man på ett effektivt sätt hanterar resurser, till exempel underhåll av teknisk utrustning, så att simuleringsaktiviteterna blir kostnadseffektiva. Körsimuleringsmetodiken som en länk i en verktygskedja har också beaktats angående synergier, kopplingar och möjligheter till samverkan med andra forskningsmetoder. Förstudien har resulterat i: - En översikt av området avancerad körsimulering globalt. - En sammanställning av för- och nackdelar med kommersiell respektive egen utveckling av simuleringsmjukvara. - En kartläggning av pågående simulatoraktiviteter i Sverige, inom Chalmers och på VTI. - Ett förslag till samarbetsstrategi inom området körsimulering.

Abstract [en]

Driving simulation is a large and truly inter-disciplinary research field. It involves visualization, vehicle dynamics, motion cueing, sound rendering and much more. Furthermore, research conducted in driving simulators has applications in almost all areas of transportation from road, infrastructure and vehicle design to human behaviour and human factors. Apart from research applications, other important areas using driving simulation are for example product development, training and education, demonstration and visualization, race car tuning and gaming. The pre-study reported here has been conducted on assignment from Chalmers. The focus has been on how to build and maintain competence and knowledge in the field of driving simulation, and how to efficiently manage resources, such as maintenance of the technical equipment, for simulation activities to become cost effective. Also, the driving simulation methodology as one link in a tool chain has been considered concerning synergies, connections and cooperation possibilities with other research methodologies. The pre-study has resulted in: - A survey of the field of advanced driving simulation globally. - A synthesis of pros and cons of commercial and own developed simulation software. - A review of on-going simulator activities in Sweden, at Chalmers and at VTI. - A proposal for a cooperation strategy in the field of driving simulation.
