Bosch Research Explores Intelligent Infrastructure for Autonomous Driving

Renningen, Germany – On October 14, 2025, Bosch Research unveiled the results of the publicly funded Shuttle2X project. Led by Bosch Research, the initiative investigated how intelligent infrastructure and vehicle-to-everything (V2X) communication can make automated driving safer and more efficient, particularly in complex urban environments.

The project aimed to overcome the limitations of onboard sensors by integrating external data sources. In dense city traffic, obstructed views can lead to unnecessary stops or overly cautious driving. Shuttle2X addressed this by incorporating data from infrastructure sensors, such as traffic lights and sensor towers, and communicating with traffic systems to create a more comprehensive understanding of the surroundings.

A key development is a hybrid safety concept that combines data from the vehicle's own sensors with external information. This integrated approach allows for more reliable decision-making in safety-critical situations. The concept received positive evaluation from TÜV SÜD following thorough testing. Additionally, the project tested and contributed to the refinement of international standards for vehicle communication, like the Collective Perception Message.

Real-world tests were conducted in locations including Karlsruhe, Bad Wimpfen, and Renningen. The outcomes of the Shuttle2X project provide valuable insights for the development of next-generation semi-automated (L2/L3) and fully autonomous (L4) driving systems for both private and commercial applications.
