“Digitaler Knoten 4.0” is the name of a forward-looking project in the field of automated and connected driving which was kicked-off in Braunschweig on 17 January 2017. It is one of four projects that receives funding from the German Federal Ministry of Transport and Digital Infrastructure. Goal is the development of digital solutions for traffic junctions (intersections) with mixed traffic (automated and nonautomatic vehicles, cyclists, and pedestrians) in urban areas. For this project, a digital test field – AIM(Intelligent Mobility Application Platform), which was already developed by DLR in Braunschweig in 2014 for research purposes, is used.

OECON Products & Services is part of this project and responsible for OECON is responsible for:

  • provision of GNSS-correctional data (in cooperation with AXIO-NET), including the direct communication with vehicles (V2X ITS-G5)
  • positioning of non-motorised road users
  • application development to support the inclusion of non-motorised road users


This project is funded by the Federal Ministry of Transport and Digital Infrastructure

project funding reference number: 16AVF1008E.

Background & Motivation

Most research activities in Germany regarding automated and connected driving are focused on motorways. The project „Digitaler Knoten 4.0“ however focuses on traffic in cities. The big challenge is thereby the complex mixed traffic at urban intersections where motorised and non-motorised road users meet.
Automated and connected driving can become reality in everyday life however extensive research is still necessary. It offers considerable potential to increase road safety and to reduce emissions and fuel consumption. Furthermore, researchers are certain that it will also lead to an improvement of traffic efficiency and to the sustainable consolidation of Germany as respectable place for business and innovation. The connected acquisition and guidance of mixed traffic and of regarding cooperative driving operations at inner city junctions is thereby a key to “Mobility 4.0”
