In this paper the results of a ex-ante impact assessment study of advanced driver assistance systems are presented. The paper focuses on two systems, namely autonomous intelligent cruise control and intelligent speed adaptation supporting different longitudinal driving tasks (car-following and speed choice). The paper addresses the impacts of these systems on efficiency, reliability, driving comfort and safety by microsimulation, for different penetration levels and bottleneck lay-outs. It turns out that the deployment of cruise control improves bottleneck capacity. The bottleneck reliability however deteriorates in most cases. The impact on traffic safety is undetermined. From the simulation experiments it turns out that ISA has no effect on capacity. Also, no substantial contribution to the bottleneck reliability could be established. It was expected that ISA would yield significant safety benefits. However, these benefits could generally not be established using the assessment methodology applied in this research.
