Technology

DRIVE C2X focuses on communication among vehicles (C2C) and between vehicles, a roadside and backend infrastructure system (C2I). Previous projects such as PReVENT, CVIS, SAFESPOT, COOPERS, and PRE-DRIVE C2X have proven the feasibility of safety and traffic efficiency applications based on C2X communication. DRIVE C2X goes beyond the proof of concept and addresses large-scale field trials under real-world conditions at multiple national test sites across Europe.

The systems to be tested are built according to the common European architecture for cooperative driving systems defined by COMeSafety, thus guaranteeing the compliance with the upcoming European ITS standards. This approach also ensures that the results of DRIVE C2X have long-term validity on European level, giving system developers as well as decision makers on the industry and authority side the necessary decision confidence.

To gather correct results from the field operational tests for cooperative systems, the technological basis is a fundamental prerequisite. DRIVE C2X relies on results from the PRE-DRIVE C2X project in terms of specification, hardware and software prototypes, test environment and integrated simulation tool set developed. The basis comprises different technological components, namely the communication system (radio, communication protocols), facilities, human machine interface, applications and management.

Compared to the PRE-DRIVE C2X, recent technology progress make enhancements necessary, as

  • the ongoing ITS standardization activities is finalizing its first series of standards and is expected to progress dynamically
  • the DRIVE C2X system should be as much as possible compliant to the most recent versions of the standards
  • specific requirements of the test sites require adaptations of the basic system.

For the first time in Europe, DRIVE C2X is also implementing and testing a concept for the integration of a data backend. Therefore enabling commercial services based on C2X communication data to private and commercial customers. Such services are expected to become a major revenue source for cooperative driving systems and can be the key for successful implementation of this technology on European roads.
