The study presented concerns the use of instrumented cars in monitoring driver behaviour. Of special interest is whether the presence and monitoring of an experimenter affect the behaviour of the test person. Furthermore, the study measures the effect of visible instrumentation. The paper starts with a brief overview of current research. The main part consists of a presentation of the research project. An instrumented car was used and the test persons were shown a computer and a camera to be used to monitor the drivers' behaviour. Following this the test person drove the same route six times. Four of these were with visible equipment and with the experimenter. The other two times the visible PC and computer were removed and the test person drove alone under the impression of not being monitored at all. However, all of the times the drivers behaviour was monitored. Drivers' speed, acceleration and deceleration were measured. A questionnaire concerning the awareness of different driving behaviour was also answered after the test.
