The increasing number and complexity of IVIS and ADAS require an accurate and timely assessment of their impact on traffic safety already in the course of the development process. Goal of the present work is the determination of the suitability and sensitivity of the tool I-TSA with special regard to the discrimination of visual and cognitive workload and the detection of learning effects. The tool was developed by the German Research Consortium 'INVENT'. 41 subjects drove for about 1 hour in a static simulator. The drive on a two-lane motorway consisted of 4 sections with both easy and difficult road shapes and traffic conditions including several interaction tasks with IVIS and ADAS at different stages of integration and adaptivity. The successful induction of high workload levels could be detected by both objective and subjective measures. Highly significant differences in safety were found between different levels of difficulty of primary and secondary driving tasks (validity) as well as between the sections with integrated and non-integrated behaviour of the IVIS (sensitivity). The I-TSA analysis also showed the possibility to discriminate between visual and cognitive workload and detected differing learning effects for different degrees of task difficulty.
