Regardless of which traffic inspector judges a specific driving test, the judgement is to be equal. Cognitive qualities are judged in the driving test by observing actions and behaviours. The purpose of this essay was to investigate, from a theoretical perspective, how traffic inspectors judge cognition, in order to investigate differences and similarities. Three analyses were made, based on twelve interviews with traffic inspectors working at two of the Swedish Road Administration’s offices for driving license tests. The traffic inspectors were asked to describe what is important in a car driver. All formal driving test criteria were mentioned by some informant. In addition to the criteria, many other concepts were mentioned by a few persons each. These concepts belong to the areas cognitive psychology, general psychology, car driving and overall qualities. The three most mentioned concepts, including criteria and other concepts, were attention, experience and risk awareness. Seven driving test criteria were defined by the traffic inspectors. Many different concepts were used to define the criteria and all criteria were defined differently by the informants. The definitions were divided into categories. The categories preparations, actions and perception were used for all criteria. An analysis about how concepts were connected to each other was made, in order to find all associations made with each concept.

Background: The Swedish driving licence test is a criterion-referenced test resulting in a pass or fail. It currently consists of two parts - a theory test with 65 multiple-choice items and a practical driving test where at least 25 minutes are spent driving in traffic. It is a high-stakes test in the sense that the results are used to determine whether the test-taker should be allowed to drive a car without supervision. As the only other requirements for obtaining a licence is a few hours of hazard education (and a short introduction if you intend to drive with a lay instructor) it is important that the test result, in terms of pass or fail, is reliable and valid. If this is not the case it could have detrimental effects on traffic safety. Examining all relevant aspects is beyond the scope of this licentiate thesis so I have focused on reliability. Methods Reliability for both the theoretical and practical test results was examined. As these are very different types of tests the types of reliability examined also differed. In order to examine inter-rater reliability of the driving test 83 examiners were accompanied by one of five selected supervising examiners for a day of tests. All in all 535 tests were conducted with two examiners assessing the same performance. At the end of the day the examiners compared notes and tried to determine the reason for any inconsistencies. Both examiners and students also filled in questionnaires with questions about background and preparation. As for studying decision consistency and decision accuracy of the theory test, three test versions (a total of around 12,000 tests) were examined with the help of methods devised by Subkoviak (Subkoviak, 1976, 1988) and Hanson &amp; Brennan (Brennan, 2004; Hanson &amp; Brennan, 1990). Results The results from two research studies concerning reliability were presented. Study I focused on inter-rater reliability in the driving test and in 93 per cent of cases the examiners made the same assessment. For the tests where their opinions differed there was no correlation to any of the background variables or other variables examined except for three, which had logical explanations and did not constitute a problem. Although there were cases where the differences were due to different stances on matters of interpretation the most common suggested cause was the placement in the car (back seat vs. front seat). Although the supervising examiners gave both praise and criticism as to how the test was carried out the study does not answer the question whether the tests were equal in terms of composition and difficulty. In Study II the focus was on decision consistency and decision accuracy in the theory test. Three versions of the theory tests were examined and, on the whole, found to be fairly similar in terms of item difficulty and score distribution, but the mean was so close to the cut-score (i.e. the score required to pass) that the pass rate differed somewhat between versions. Agreement coefficients were around .80 for all test versions (between .79 and .82 depending on method). Classification accuracy indicated an .87 probability of a correct classification. Conclusion It is important to examine the reliability and validity of the driving licence test since a misclassification can have serious consequences in terms of traffic safety. In the studies included here the rate of agreement between examiners is deemed as satisfactory. It would be preferable if the classification consistency and classification accuracy, as estimated by the methods used, were higher for the theory test, given its importance. While reliability in terms of agreement between raters/examiners or consistency and accuracy of classification are routinely examined in other contexts, such as large-scale educational testing, this is not often done for the driving licence tests. At the same time, the methods used here can be transferred to contexts where such properties are generally not examined. Collecting information about test-takers and examiners, like in Study I, can provide evidence concerning possible bias. Examining to what extent decisions are consistent is one important aspect of collecting evidence that shows that test results can be used to draw conclusions about driver competence. Still, regardless of outcome, validation is a process that never ends. There is always reason to examine various aspects and make further improvements. There are also many other relevant aspects to examine. A prerequisite for the validity of the score interpretation of a criterion-referenced test like this one is that the cut-score is appropriate and the content relevant. This should therefore be the subject of further research as the validation process continues.

The objective of this project is to develop a driving test using a Digital Human Modeling tool (DHM), specifically IPS IMMA, which will allow the evaluation of the ergonomics of the interior of vehicles as currently demanded by the automotive companies. Thus, improving both the design and the design process. This will involve a study of the driving and the tasks carried out by a real person to end up programming them in the DHM software. Based on this study an interface is suggested that guides engineers or ergonomists to design their own driving tests and enable them to evaluate their own designs without a high specialization in DHM tools and software. Taking into account the already present autonomous cars and their future development, the conceptual design of a two positions steering wheel (autonomous/manual driving) will be introduced as an example to be added in the driving test. This example is intended to show how DHM tools can be used to evaluate different designs solutions in early stages of the product development process. This project will be a contribution to one of the sections of the ADOPTIVE project carried out at the University of Skövde and in collaboration with Swedish automotive companies.

n this work is processed a summary of selected driving parameters of vehicles, methods of measuring and use in the automotive industry or related branch especially. This work is focused on driving tests of vehicles and measurement driving parameters of vehicles. As part of this work was done measurements parameters of vehicles driving in various driving regimes and subsequent analyse of obtained data. The result of this work is determination methodology division driving regimes and evaluation the impact of driving regimes on to ride a car in a directional curve.

This thesis deals with the analysis of the car driving characteristics depending on the type of drive wheels. The first chapter defines the basic theoretical cars concept as well as procedures for determining the individual variables needed to identify the driving dynamics of vehicles. The practical part describes the plan and the progress of realized measurements on a selected pattern of vehicles, and the measured values are interpreted. The final part deals with the evaluation of the performed measurements and the data identified within these measurements.
