Test Bed Lower Saxony – acquisition technology

The focus of the Test Bed Lower Saxony is the comprehensive evaluation of traffic scenarios and the development of new driving assistance and automation systems. This is made possible by our modern data acquisition technology.

Role of the acquisition technology at the Test Bed Lower Saxony

The acquisition technology at the Test Bed Lower Saxony is made up of numerous sensor systems attached to support masts located along a section of motorway. The aim is to record all vehicles and other objects in this area in order to evaluate overtaking manoeuvres, approach and departure manoeuvres and driver behaviour under different weather conditions, among other things. This information is used as a basis for improving the quality of the data generated at the test field. This data then serves as a basis for improving road safety and for the development of future driving assistance systems.

The acquisition technology at the Test Bed Lower Saxony records all vehicle positions with high precision, around the clock and in all weather conditions. The collected data is made available for further analysis as well as for live services. In addition to the acquisition technology, the communications technology also plays a major role at the test field. Car2X technology, for example, is attached to the support masts for communication with the test vehicles.

Who is interested in the data gathered using the acquisition technology?

The data collected using our data acquisition technology at the test field is available to a wide variety of users, including representatives from:

  • Industry
  • Scientific institutions
  • Government
  • Relevant associations

The findings generated using the test field are of interest to these users for a variety of reasons, such as for:

  • the development of sensors or driving functions for automated vehicles
  • research on automated and networked mobility
  • information on automated or networked driving
