What's New in SET-IT

The Systems Engineering Tool for Intelligent Transportation (SET-IT) is a software tool that integrates drawing and database tools with the Architecture Reference for Cooperative and Intelligent Transportation (ARC-IT) so that users can develop project architectures for ITS. SET-IT provides enhanced capabilities for project architecture development that go beyond the capabilities offered in RAD-IT. Be sure to install the latest updates to Microsoft Windows & Office before running SET-IT.

SET-IT Version 9.4 updated October 2026, now available for download, includes the following new-and-improved features:

• New Standards Map diagrams that let you output a Visio diagram for each service package showing the relevant standards for the elements, interfaces, and the service package as a whole.
• New diagram option to create a Layer 3 physical view diagram. Allowing for detailed analysis of the components and interfaces that make up a level 2 physical object.
• New diagram export option to generate images of any diagram for use in other tools.
• A Multi-Access Edge Computing (MEC) object is now available as an option to the connected vehicle roadside equipment (RSE) object on many service package diagrams.
• Now able to assign Data Distribution System (DDS) physical object to any Center class shape on a diagram which was previously unallowed since DDS is a support-class/communications-type object.
• Now able to move a flow on a diagram between two objects that are functionally identical without blanking out the flow.
• Diagram settings are now remembered from previous sessions and the Definitions grids now remember the previous sort order when reopened.
• A pre-installed custom spelling dictionary with architecture-specific terms.
• Support for user-defined Resource objects in Enterprise view.
• New class icon shapes for physical object shapes.
• New P-Object grouping box stencil item.
• Improved reporting during the Update Diagram process.
• Improved handling of Joint Agreements which are now restricted to stakeholder groups.
• Updated Physical Object Standards handling to account for regions.
