Abstract [en]

The first aim of the present study was to identify key items which are rated differently by drivers from Finland, Sweden, Greece and Turkey. The second aim was to examine how these key items relate to drivers’ self-reported accident involvement. Similar comparisons have previously been conducted in Europe but these have only included items classified as violations and errors, but not lapses. A sample of Finnish (N = 200), Swedish (N = 200), Greek (N = 200) and Turkish (N = 200) drivers completed the driver behaviour questionnaire (DBQ) and reported their accident involvement during the previous 3 years. The results showed that nine key items (which drivers from different countries rated differently) could be identified. These items included two aggressive violations, four ordinary violations, three lapses, but no errors. Out of these nine items, five items (Become angered by a certain type of driver and indicate your hostility by whatever means you can, Disregard the speed limit on a motorway, Overtake a slow driver on the inside, Pull out of a junction so far that the driver with right of way has to stop and let you out and Get into the wrong lane approaching a roundabout or a junction) could explain differences in drivers’ self-reported yearly accident involvement when all four countries were taken together. At the same time, none of the items could explain differences in self-reported yearly accident involvement in Finland and Sweden while one of the items (Overtake a slow driver on the inside) could explain differences in self-reported yearly accident involvement in Greece and two of the items (Become angered by a certain type of driver and indicate your hostility by whatever means you can and Disregard the speed limit on a residential road) could explain differences in self-reported yearly accident involvement in Turkey. This shows that different countries have different problems with regard to aberrant driving behaviours which need to be taken into account when promoting traffic safety interventions and the driver behaviour questionnaire (DBQ) can be used to diagnose risk areas and to better inform road safety practitioners within and between countries.

Abstract [en]

The first aim of the present study was to examine the factor structure of the traffic locus of control (TLOC)scale in a Swedish sample of drivers. The second aim was to examine if this scale can be used to predict drivers’ speeding behaviour. A sample of Swedish car owners (N= 223) completed a questionnaire including questions based on the traffic locus of control (T-LOC) scale as well as questions about their speeding behaviour. The results showed a five factor solution including own skills, own behaviour, other drivers, vehicle/environment and fate. Own behaviour and vehicle/environment could be used to predict drivers’ speeding behaviour on roads with a 90 km/h speed limit while none of the variables included in the traffic locus of control (T-LOC) scale could be used to predict drivers’ speeding behaviour on roads with a 50 km/h speed limit. On 90 km/h roads own behaviour was positively related to drivers’ speeding behaviour while vehicle/environment was negatively related to their speeding behaviour.

Abstract [en]

The aim of the present study was to examine if there are differences in drivers’ propensity to have different types of intelligent speed adaptation installed in their cars depending on the sample of drivers (i.e. Swedish or Turkish), their aberrant driving behaviours (i.e. violations and errors), and/or the technical solution used (i.e. speed limit information, advisory, supportive and intervening systems). A sample of 224 Swedish and 316 Turkish drivers completed a questionnaire including questions based on the driver behaviour questionnaire (DBQ) as well as questions about the drivers’ propensity to have different types of intelligent speed adaptation installed in their cars. The results showed that the Swedish sample of drivers was less positive than the Turkish sample of drivers towards having the advisory, supportive and intervening systems installed. Furthermore, drivers who frequently commit violations were less positive towards having any of these systems installed than were drivers who commit violations less frequently, while drivers who frequently make errors were more positive towards having the systems installed than were drivers who make errors less frequently. Both the Swedish and the Turkish sample of drivers were most positive towards having the speed limit information system installed, followed by the advisory system on second place, the supportive system on third place and lastly the intervening system on fourth place.

Abstract [en]

Many different classification schemes have been used in the analysis of road traffic accidents but the agreement between coders using the same classification scheme is rarely tested and/or reported. As a high intercoder agreement is a prerequisite for a study’s validity, this is a serious shortcoming. The aim of the present study was, therefore, to test the intercoder agreement of the Driving Reliability and Error Analysis Method (DREAM) version 3.0 by letting seven coders from different European countries analyse and classify the causes of the same four accident scenarios. The results showed that the intercoder agreement for genotypes (contributing factors) ranges from 74% to 94% with an average of 83%, while for phenotypes (observable effects) it ranges from 57% to 100% with an average of 78%. The results also showed that weaknesses in classification schemes, methods, training of coders as well as in presentation of accident information can be identified by testing the intercoder agreement.

Abstract [en]

The aim of the present study was to examine if there are any cross cultural differences between Swedish and Turkish drivers’ rating of the variables in the theory of planned behaviour (TPB) with regard to complying with the speed limit. A sample of 219 Swedish and 252 Turkish drivers completed a questionnaire including questions based on the theory of planned behaviour (i.e. regarding attitude, subjective norm,perceived behavioural control, intention and behaviour). The results show that country differences in drivers’ intention to comply with the speed limit as well as their self reported compliance could be explained by differences found in their attitude, subjective norm and perceived behavioural control. Furthermore,drivers who live in a country with fewer road traffic fatalities (i.e. Sweden), compared with driverswholive in a country withmore road traffic fatalities (i.e. Turkey),reported amore positive attitude towards complying with the speed limit, a more positive subjective norm, a higher perceived behavioural control, a higher intention and a larger proportion of the time spent complying.

Abstract [en]

Objectives: Intelligent speed adaptation (ISA) aims to help drivers keep to the speed limit. The aim of the present study was therefore to examine if there are differences in drivers’ propensity to install intelligent speed adaptation systems due to the drivers’ country of residence, their aberrant driving, and the technical solution used. Methods: 224 Swedish and 316 Turkish drivers completed a questionnaire including the DBQ and questions about the drivers’ propensity to have different ISA systems installed. Results: Swedish drivers were less positive than Turkish drivers towards installing ISA systems. Drivers who frequently commit violations were less positive towards installing ISA systems, while drivers who frequently make errors were more positive towards installing the systems. Both Swedish and Turkish drivers were most positive towards installing the speed limit information system, followed by the advisory system, the supportive and lastly the intervening system.

Abstract [en]

The aim of this study was to examine drivers’ view on their own speeding behaviour by focusing on belief based measures as suggested by the theory of planned behaviour. A sample of car owners (N = 162) completed a questionnaire including both direct and belief based measures of the latent variables in the theory of planned behaviour. The results showed that indices constructed with direct measures of attitude, subjective norm and perceived behavioural control made a larger contribution to the prediction of drivers’ intention to exceed the speed limits in both urban and rural environments, than did indices constructed with belief based measures. An extensive set of belief composites was produced and standard multiple regressions showed which of these contributed to the prediction of attitude, subjective norm and perceived behavioural control, as well as intention. The use of these findings is discussed.

Abstract [en]

The power of two different theoretical frameworks, the theory of planned behaviour (expanded to include moral norm) and the driver behaviour questionnaire, to predict and explain drivers' speeding behaviour are compared and a combined model is suggested. One hundred and seventy-five test drivers, participating in a large-scale ISA-evaluation, answered a questionnaire in spring 2000. Based on the questionnaire data, logged speeding in autumn 2001 was predicted and LISREL-analysis was used for structural equation modelling. According to the results the two frameworks, alone or in combination, could explain between 38 and 53% of self-reported speeding and between 24 and 26% of logged speeding. A combination of the theory of planned behaviour and the driver behaviour questionnaire is presented and implications for the understanding of driver speed control are discussed.

Abstract [en]

Different systems of intelligent speed adaptation (ISA) have already been tested in the field and large-scale implementation is being discussed. But do we really know how these systems affect drivers during long-term use?Between 2000 and 2003 a total of 61 test drivers had an ISA speed warning device installed in their vehicles. Data from these trials show that,initially, the device greatly reduced the amount of time the majority of test drivers spent above the speed limit, and to some extent also reduced their mean speeds, but this effect decreased with time. Further analyses of 27 of the 61 test drivers then showed that the activation of the warning system affected different drivers in quite a homogenous way, with regards to attitude, subjective norm and self-reported behaviour, but not with regards to perceived behavioural control. After activation,long-term use did, however, affect the test drivers in a homogenous way with regards to attitude, subjective norm and self-reported behaviour, as well as perceived behavioural control. When considering these results it must be remembered that the device tested was a first generation ISA speed-warning device and with more research we think that different ISA-systems could be improved and the effects made more stable during long-term use.
