STREAM - Secured Traffic Data for Reliable and Efficient Automated Mobility

Within the context of the mobility transition, connected and cooperative transport systems (C-ITS) as well as connected cooperative automated mobility (CCAM) are broadly discussed topics. Connected driving is seen as one of the enablers for automated mobility. A hitherto unsolved problem in this field is how to establish truly secure and trustworthy communication systems. Without those systems, data and information will only be deemed informative by vehicles and will not lead to adapted driving behavior. Only data and notifications provided in a resilient manner can be classified as safe by road users, which is the basis for an increasingly wide implementation of CCAM on European roads. 

The aims of the joint Czech-German STREAM project, therefore, are

• to build a complete chain of technologies for creating and transmitting trustworthy information to connected vehicles,
• to harmonize the infrastructure for trustworthy and reliable data and communication in Germany and the Czech Republic.

As automotive and rolling stock is an important industrial sector for both countries, compatibility of vehicles and infrastructure between these regions is critical for creating and implementing new mobility solutions based on digital communication. The project inlcudes work in the areas of detection, cybersecurity pilots in both urban and rural environments as well as production testing methods.

International Excellence in Cross-Border Cooperation

The consortium consists of INTENS Corporation s.r.o., PiVa AI s.r.o. and the Czech Technical University in Prague on the Czech side, and Dresden Elektronik Verkehrstechnik GmbH and Fraunhofer IVI on the German side. Together with further associated partners, they have a unique set of know-how and capabilities, ranging from software and hardware development to testing and evaluation. Having the option to test individual sets of equipment in both countries provides starting ground for the definition of new standards for trustworthy information from CCAM operating in both countries, with the great potential of becoming the new standard for infrastructure on a European level.

Within the scope of the project, the partners will construct and validate a pilot system in which the infrastructure automatically recognizes an event and forwards this information to approaching vehicles in a consistent and trustworthy manner via Car2X networking. Communication is secured via a so-called Public Key Infrastructure (PKI) and events within the data and information are captured by anomaly detection algorithms. As a result, the prerequisite for PKI Level2 readiness in synchronization with the national and international PKI will be created, which is especially important for infrastructure operators.

During the project, the Czech partners will primarily focus their activities on use cases for highways, while the German partners will investigate urban scenarios. Their fundamental premise represents a complete paradigm shift in today’s mobility: Whereas vehicles and drivers currently handle the task of driving entirely on their own, in the future, infrastructure-provided information will first assist with information, then with assistance functions, and finally with driving functions.
