A microscopic simulation tool has been developed for analyzing the traffic flow impacts of Autonomous Intelligent Cruise Control (AICC). The model is capable of representing AICC-equipped vehicles with different support functionalities in mixed traffic composition. It enables the simulation of traffic processes on uniform motorway stretches as well as on motorway discontinuities such as bottleneck segments. The applied car-following model distinguishes different car-following situations in which different parameters are applied for an individual driver. The use of a time scan of 0.1 s and stochastic elements of the user class variables - such as desired speed and delay - make a realistic representation of today's motorway traffic possible. Calibration results for the reference case show a good resemblance with practice, including a distinction between pre-queue and queue discharge flow rates. The lane distribution is also according to empirical observations. (A*)
