Functional Road Classification (FRC) Document
How do navigation systems, digital maps, and transport planning tools “understand” the role of each road?
This is where Functional Road Classification (FRC) comes in — structuring road networks based on their function, balancing mobility and access.
To bring clarity in this topic, TISA has put together an introductory document on FRCs that explains these concepts in a clear and structured way — without going too deep into technical detail.
It introduces the foundational principles of Functional Road Classifications as applied in digital mapping systems, explaining how these classifications support key use cases such as routing, map matching, and transportation planning.
The document
- Explains the core concepts behind FRC frameworks
- Highlights common challenges in their application and interpretation
- Focuses on standard, real-world use cases, which represent the majority of implementations
- Provides a broad yet practical overview to support consistent understanding across stakeholders
The document is freely available on the TISA website and can be found through this link.
A more advanced follow-up document will address technical details and some non-standard application scenarios.
