Impact of automated driving strategies on future traffic dynamics — •Arne Kesting, Martin Treiber, Martin Schönhof, and Dirk Helbing — Technische Universität Dresden, Institute for Transport & Economics

Adaptive cruise control (ACC) automatically accelerates or decelerates a vehicle to maintain a selected time gap, to reach a desired velocity, or to prevent a rear-end collision. Furthermore, an increasing market penetration of ACC systems will make an impact on the traffic dynamics, and, therefore, leads to interesting questions about the future traffic flows consisting of human drivers and automated longitudinal control.

Microscopic traffic modelling is an appropriate approach to investigate the traffic dynamics. Furthermore, sufficiently high equipment levels of ACC systems provide an interesting option to enhance the traffic performance by automated driving strategies that are designed to increase the capacity and stability of traffic flows. We propose a driving strategy for ACC that adapts the driving style dynamically to the overall traffic situation. We analyse this driving strategy by means of simulation and show how the system’s performance depends on the equipment level. Remarkably, we find that already a small amount of ACC-equipped cars and, hence, a marginally increased free and dynamic capacity, can lead to a drastic reduction of traffic congestion.
