Infrastructure support levels for automated driving (ISAD)
Added:12/06/2025
Contributor:FAME
Current consensus
Infrastructure support levels for automated driving are five infrastructure (ISAD) classes designed based on multiple potential dimensions.
Explanation
Grade of involvement of TMC-iTMC in automated functions control:
- Bullet
- Readiness for specific levels of vehicle automation
- Physical infrastructure adherence to specific technical standards or condition of repair
- Availability of additional physical infrastructure support elements (e.g. special markers)
- Wireless communication infrastructure capabilities (V2I & I2V)
- Digital infrastructure (Local Dynamic Map Layers)
- Back-office information support functionality
- The ISAD classification is implemented as an automated service in the ASFINAG database, which in the future could also be used for dynamic up- and downgrade of the classes on several segments.
