U.S. Department of Transportation Updates Training for the Architecture Reference for Cooperative and Intelligent Transportation (ARC-IT)

The U.S. Department of Transportation (USDOT) has updated the training material accompanying version 9.0 of its Architecture Reference for Cooperative and Intelligent Transportation (ARC-IT), the Regional Architecture Development for Intelligent Transportation (RAD-IT) and the Systems Engineering Tool for Intelligent Transportation (SET-IT).

The online training courses are available directly from the ARC-IT website, providing students with an understanding of how to navigate and use ARC-IT, use the software tools RAD-IT & SET-IT, and how to Use & Maintain a regional ITS architecture.

ARC-IT provides a common framework for planning, defining, and integrating intelligent transportation systems. RAD-IT supports development of regional and project ITS architectures using ARC-IT as a starting point. SET-IT integrates drawing and database tools with ARC-IT so that users can develop detailed ITS project architectures. ARC-IT and the accompanying tool sets help implementers develop architecturesto effectively meet their needs and facilitate efficient, secure, and interoperable ITS deployments.

ARC-IT and its accompanying software tools are available at no cost from ARC-IT website.

MARCH 2021

The Architecture Reference for Cooperative and Intelligent Transportation (ARC-IT) tools that support development of locally customized Regional Architectures and projects have been updated with convenience, performance and reliability enhancements:

  • The Regional Architecture Development for Intelligent Transportation (RAD-IT) update includes revisions to the Communications tab to support more configurations, revised flow and interconnect diagram outputs, and revisions to the agreements tab. Read more about What's New in RAD-IT.
  • The Systems Engineering Tool for Intelligent Transportation (SET-IT) update includes new features designed to make editing of complex diagrams easier, including a new ‘line text’ tool and revised Enterprise diagram generation, as well as increased options for user-defined information flows. Improvements have been made to both tools to improve performance, reliability and resilience. Read more about What's New in SET-IT.

Both tools are immediately available at no cost. For more information about ARC-IT and these tools, visit the ARC-IT website.
