The interest in in-vehicle Advanced Driver Assistance Systems(ADAS) is increasing. New systems such as Adaptive Cruise Controlsand Collision Avoidance Systems are currently introduced ata rapid pace. ADAS can both substitute and complement traditionalinfrastructure based safety improving countermeasures. Toexploit the full potential of these systems, it is necessary to estimatethe systems future impact already at early developmentstages. This paper presents a traffic simulation framework foranalysis of the aggregation of individual driver/vehicle behaviourdue to ADAS to effects on the traffic system. Application of thesimulation framework is exemplified by a study of centre line rumblestrips on rural roads. The effects of physical milled rumblestrips are compared to the effects of “virtual” in-vehicle rumblestrips for both alert and sleep deprived drivers. The use of trafficsimulation made it possible to study the combined impact ofchanges in drivers’ free driving speed, reaction time and overtakingbehaviour. Indications that the different rumble strips have animpact on average journey speeds were found amongst the simulationresults. Changes in safety indicators that can be related tochanges in overtaking behaviour were also observed.
