Abstract
The thematic focus of this Bachelor thesis is laid on investigations into the behavior of automated vehicle systems. In recent years, apart from the already commercially available Adaptive Cruise Control (ACC), an upcoming system called Cooperative Adaptive Cruise Control (CACC) has been developed to control the speed of vehicles. The goal of this work is to compare the behavior of these systems on the basis of empirical data from car-following experiments. By analyzing the microscopic properties response time, headway, string stability, and energy consumption, one can estimate the impact on traffic performance. The three modes considered in this thesis are Human drivers, ACC, and CACC. While ACC does not exhibit a significant improvement compared to human drivers, it can be concluded that the additional vehicle-to-vehicle communication incorporated in the CACC system allows a substantially higher traffic flow. The findings show that this advancement results from fast response times, a short headway and string stable behavior in car-following scenarios. Show more
