The ITS-102 specification refers to ETSI’s Intelligent Transport Systems (ITS) standards, which define communication, security, and application requirements for cooperative vehicular and transport networks. These specifications ensure interoperability, safety, and secure data exchange between vehicles, roadside infrastructure, and transport management systems.

The ITS-102 series is part of ETSI’s technical specifications for Intelligent Transport Systems. While “ITS-102” is shorthand, the actual documents are numbered (e.g., TS 102 940, TS 102 894-1) and cover different aspects:

• TS 102 940 – Security Architecture

  • Defines the communications security architecture for ITS.
  • Covers security management, including certificate handling, trust models, and cryptographic mechanisms.
  • Ensures that vehicles and infrastructure can exchange authenticated and confidential data.
  • Release 2 (2021) focuses on interoperability and robust security for cooperative ITS.

• TS 102 894-1 – Application Requirements

  • Specifies facility layer structure and functional requirements for ITS applications.
  • Provides guidelines for how ITS services (like traffic management, safety alerts, and infotainment) interact with the communication stack.
  • Ensures that applications are standardized so vehicles and roadside units can work seamlessly together.

• ETSI ITS Committee Role

  • ETSI develops these standards to accelerate ITS deployment across Europe and globally.
  • Focus is on interoperability, safety, and efficiency in transport systems.
