Communication Control Unit (CCU)
Wireless communication between vehicles and their surroundings (Vehicle-to-Everything [V2X] or Car2X), including communication between a vehicle and road infrastructure (Vehicle-to-Infrastructure [V2I] or Car-to-Infrastructure [C2I]) and between vehicles (Vehicle-to-Vehicle [V2V] or Car-to-Car [C2C]) according to ETSI ITS G5 or C-V2X standard
Application Unit (AU)
Application logic, configuration, and parameterization
Roadside ITS-Station also Intelligent Roadside Station (IRS), Roadside/Road Side Unit (RSU)
Information exchange and communication
• IRS consists of several parts, usually a CCU and an AU, connected via network technology
• The parts of an integrated IRS are often located at a distance from each other, so that the CCU is up on the traffic light post and the AU is the intersection in the traffic control box
Vehicle ITS-Station also Intelligent Vehicle Station (IVS), On-board Unit (OBU)
Information transmission and reception
• Communication between vehicles and infrastructure
• Communication between vehicles (Vehicle-to-Vehicle [V2V] or Car-to-Car [C2C])
Pedestrian detection camera
• Detecting the movement of pedestrians
• Sending the information about pedestrians’ position, direction, and speed to the AU
(Camera images are neither sent further nor saved)
Traffic camera
• Recognizing and counting the vehicles
• Sending the information about recognized objects, in particular of test vehicles crossing the intersections
(Camera images are neither sent further nor saved)
Charging Station
A plug socket for Mode-2 charging cable to charge electric vehicles
Radio-frequency identification (RFID)
Identification by means of electromagnetic waves: recognizing RFID-tags of test vehicles (e.g. so that the charging station could be enabled)
IT-center
• Application and analysis systems for processing zthe data from the Testfield
• Saving the generated data
(The Testfield is connected to the IT-Center via 4G-communication)
