This article gives an overview on the main results of driving behaviour observations carried out with drivers using different IVT systems. This workwas part of the FP7 project INTERACTION (Understanding driver interactions with In-Vehicle Technologies) in which the use of mature and wide spread IVT systems, namely Cruise Control,Speed Limiter, Navigation System and Mobile Phone was investigated. The aim of the project was to gather more information about when, where and under which conditions these systems are used. The driving behaviour observations with the help of the “Wiener Fahrprobe” gave additional information on how drivers are handling with the systems and how the use of the systems is influencing the driving behaviour in normal and emergency situations. Therefore two test rides with 91 test persons in seven countries on a standardised route were carried out. On the first observation ride the test persons were using two of the IVT systems while on the second ride they were using two other systems. Therefore comparisons of the driving behaviour with and without an active IVT system could be done. The test persons were observed by two observers, one with the task to register driving errors with a standardised observation sheet (coding observer) and the other describing especially the interaction and communication behaviour of the test persons, server errors and conflicts (free observer). This article will concentrate on the observations regarding the handling with the systems and the interaction processes with other road users while using the systems.
