With the introduction of Vehicle-to-X (V2X) communication, the perception range of next generation vehicles will be extended even further. In addition to the introduction of local perception sensors in Veins, we present ArteryLTE, a holistic simulation environment for using the vehicle position data from the microscopic traffic simulator SUMO in combination with ETSI ITS G5 and LTE enabled vehicles, as well as a backend. We use the proposed simulation framework to present preliminary results for detecting lane-level traffic phenomena.},

    abstract = {Backend services enable the large-scale aggregation of vehicle data. This Floating Car Data (FCD) can be used to detect traffic disturbances. Although today's vehicles are able to determine their position on a per-lane level, FCD is typically only used on a per-street level granularity. In this paper, we show that using the fleet-data from one Original Equipment Manufacturer (OEM) alone as the database (i.e., on a backend) is indeed not sufficient to detect local, lane-level, traffic phenomena, independent from the accuracy of the vehicle localization. We thus present a high-resolution telemetry service based on heterogeneous Inter-Vehicle Communication (IVC). We introduce a novel holistic IVC simulation framework which we make publicly available and use it to experimentally verify the proposed telemetry service. Results show a significant leverage of IVC on both the resolution of FCD and the accuracy of detecting lane-level traffic phenomena.},

    abstract = {In an advanced physics course, experiments to determine the wavelength of an helium neon laser were conducted, both at school and in close collaboration with the PTB (Physikalisch-Technische Bundesanstalt) Braunschweig, using high precision instruments. Moreover, basics and fields of application of modern laser interferometry, as well as the historical context of the special theory of relativity and new developments like quantum eraser experiments, are described.},
