This presentation deals with a PhD thesis about the influence of an Intelligent Speed Adaptation system (ISA) on the driving behaviour of young, novice drivers in Austria and in the Czech Republic, with special attention on the behaviour observation method “Viennese driving test” (Wiener Fahrprobe). After a short introduction to the key data of the PhD thesis such as experimental design, hypotheses, etc., the main part of the presentation will concentrate on the method of behaviour observation and interpretation. After the discussion what advantages and disadvantages such a method has, based among others on the experiences made within the PhD study, the development of the “Viennese driving test” will be described. The parameters that should be observed, such as speed or distance keeping behaviour, but also communication with other road users, and especially the vulnerable ones, will be presented as well as the criteria a test route should fulfil. Next, route compilation, instruction and training of observers, forms to be used and similar procedural aspects are discussed. The presentation will end with a discussion of the validity of an instrument like the Wiener Fahrprobe, not least dealing with the theoretical question how obtrusive observation could influence driver behaviour, and what empirical evidence there is that the Wiener Fahrprobe functions well as a criterion for the assessment of a certain part of driver behaviour.
