ITIS Is EverywhereITIS Is Everywhere
ITIS codes are central to how ITS messages work in ATIS, IM, TMDD and TCIP
ITIS codes can be freely mixed with text ITIS sub-groupings form the top level
taxonomy for all message filtering and grouping ITIS code list is growing, with new codes being
added, but allows local codes to be easily created and used in a structured way

The Next 6 MonthsThe Next 6 Months All major development work accomplished maintenance mode XML
Develop Web services XML files Integrate with completed XML Schema file efforts Close cooperation with C2C XML working group
Revise and re-ballot standards as needed based on above (J2354 and J2540/2 rev3) Continue coordination with TMDD, TCIP, and Incident Management standards
Ensure cross-use of messages and data elements

The Importance of Coordinating The Importance of Coordinating StandardsStandards
Technical reasons Ease of development, modification, revision
Practical/functional reasons “No system is an island,” complex systems require
multiple standards that have to ‘plug and play”
Focus on common data elements & code lists, naming & coding conventions

The IM message “road work” uses the ATIS message “event” which in turn uses the IM “lane description” which in turn uses several TMDD codes, some of which come from ITIS codes. SAE ATIS
