The UTMC Technical Specification has now been transferred to TOPAS for management and maintenance. The Tech Spec documents on this site have been retained for archive purposes, frozen at the their transfer state.
The TOPAS website is available here: Topas Group - Traffic Open Products & Specifications .
The Technical Specification was at the core of what made the standards work.
This page provides UTMC Technical Specification documents. Additional helpful information may be found on the "Guidance & good practice" tab.

The Framework Specification ("TS003") defined the general architectural framework for UTMC systems.
The Framework was consciously based as far as possible on mainstream ICT practice in order to avoid expensive, bespoke, dead-end solutions.
The Objects Register ("TS004") defined the formats and structures of data objects used in UTMC systems. Some of these are geared to specific traffic system functions; others describe the road network; and a third set relates to information structures (like "predictions" or "faults").
The register is large and complex document. It is presented in three main files, together with a number of supplementary documents.
