Roadside Infrastructure

Application

• Supply of highly accurate real-time reference data from road users for connected and automated vehicles in the test field
• Long-term collection and storage of real traffic data for the development and safeguarding of automated driving functions
• Long-term collection and storage of raw sensor data for the development and safeguarding of automated driving functions
• Evaluation and analysis of connected and automated driving functions in real traffic and in simulation/in the digital twin

Technical Data

Stationary infrastructure sensor technology

• Test field Campus Melaten: 46 stationary infrastructure measuring stations along an urban circuit of 2.4 km length
• Test field B56 Aldenhoven: 11 stationary infrastructure measuring stations along a 1 km section of rural road
• Test field A44 freeway junction Jackerath: 11 stationary infrastructure measuring stations along a 1 km section of highway
• Sensor technology: two 4K dome cameras and two 128-layer rotary laser scanners (LiDARs) are used per measuring station
• Telematics: each measuring station is equipped with a V2X Roadside Unit as well as a C-V2X capable 4G cellular module and a Wi-Fi module
• Mounting height of the sensor system: 6 m above road surface
• Acquisition of position, speed, acceleration, heading, dimensions and class of each road user at a recording rate of 10-20 Hz
• Processing of standardized V2X messages (e.g. CAM, CPM, DENM)

Mobile infrastructure sensor technology

• 4 fully self-sufficient mobile measuring stations as well as a fully self-sufficient mobile server for individual collection of raw sensor data at selected road sections
• Construction in the form of trailers with hydraulically extendable mast
• Mounting height of the sensor system: 8 m above road surface
• Sensor technology: two 4K dome cameras and two 128-layer rotary laser scanners are used per measuring station
• Telematics: each mobile measuring station is equipped with a 4G cellular module and a Wi-Fi module
• Recording rates: LiDARs 10-20 Hz, cameras 10-25 Hz
• Integrated automated anonymization of raw sensor data on the mobile server - No collection of personal data
