With our partner msg Plaut Austria GmbH and in collaboration with ASFINAG, we recently conducted a study of Austrian highways in combination with the C-Roads C-ITS framework to explore the benefits of connected vehicles and infrastructure.
Leveraging our high-performance virtual testbed, CityMoS, we modelled the A23 in Vienna which is Austria’s busiest highway. Thanks to CityMoS’s advanced automated calibration, we achieved a realism score of over 95%, allowing us to explore various “what-if” scenarios and compared them to a validated baseline.
We examined the impact of a vehicle breakdown on the rightmost lane of a turn just after a tunnel exit — an area which is potentially hard to see for approaching drivers. Our findings show that with a high enough percentage of connected vehicles, the negative effects of such incidents can be significantly mitigated, leading to smoother traffic flow, enhanced safety, and even reduced CO2 emissions.
These and other results will be published in our paper titled “Traffic Flow Impact of C-ITS on Austrian Urban Highway: A Simulation Study”, authored by Alexander Paier, Jacqueline Erhart, Dr. Daniel Zehe. Dr. Jordan IVANCHEV, and David Eckhoff. It has been accepted for presentation at the ITS World Congress (ITS Congresses), held from September 17th to 20th in Dubai. Also join us at booth H5-D1 for a detailed demo of how CityMoS is paving the way for Cooperative Intelligent Transport Systems.
