RAD-IT Tool Training June 2017 Module Outcomes Explain the relationship of ITS standards to your architecture Describe how to access ITS standards information In this session, we will review the use of RAD-IT to map the interfaces of the regional or project architecture to ITS Standards. At the end of this session, you will be able to: Explain the relationship of ITS standards to architecture Describe how to access and modify ITS standards information This module will take approximately 30 minutes to complete. This Module will take approximately 15 minutes to complete.

Foundation for Standards in RAD-IT RAD-IT Tool Training June 2017 Foundation for Standards in RAD-IT ITS Standards address interfaces between ITS elements. When stakeholders have reached consensus on the interfaces (information flows) between each pair of elements in the Regional or Project ITS Architecture, then a set of standards can be identified for many of these flows. For RAD-IT to be able to identify the applicable ITS standards of an architecture, the interfaces between ITS inventory elements must be identified (which require that the inventory of ITS elements be identified). Inventory of ITS elements was discussed in Session 5 and the interfaces between them in Session 9 of this course. Image Description: The diagram showing relationships between architecture components in RAD-IT is shown with the Standards box highlighted and the other boxes except the Inventory and Interfaces boxes are grayed out.

Rule/Policy Regarding Standards RAD-IT Tool Training June 2017 Rule/Policy Regarding Standards “Identification of applicable ITS standards supporting regional and national interoperability” The FHWA Rule and FTA Policy requires that all regional ITS architectures identify the applicable “ITS standards that support regional and national interoperability”. One of the primary purposes for developing and using an architecture is to consider common standards across the region so interoperability is possible. ITS projects, according to Rule 940.11 also have to include an ‘identification of applicable ITS standards’.

ITS Standards & The ARC-IT RAD-IT Tool Training June 2017 ITS Standards & The ARC-IT ITS Standards defined for interfaces ITS standards are mapped to the interfaces of the ARC-IT. In the example shown, the flow ‘incident information’ represents information traveling from the Traffic Management Center to the Emergency Management Center. Appropriate ITS standards are mapped to information flows in ARC-IT so when you create your architecture, and use information flows from ARC-IT, RAD-IT provides you with a list of potential ITS standards. It is important to note that though most information flows of the ARC-IT have ITS standards associated with them, there are a few that do not.

Standards Tab The Standards Tab is not available in RAD-IT V8.0 RAD-IT Tool Training June 2017 Standards Tab The Standards Tab is not available in RAD-IT V8.0 Use Output / Tables to see the ITS Standards associated with the information flows of your architecture (region or project) For projects – use SET-IT to tailor Communications Profiles for a project Standards are identified on the ninth tab of RAD-IT labeled Standards. The “Standards” tab in RAD-IT 8.0 does not provide the opportunity to customize how ITS Standards activities best apply to your situation. However there are ways to generate outputs of the Standards mappings in this version that will satisfy the requirements for Rule 940 and to be able to scope your project. Use the Standards table from the Output / Tables menu to export a listing of the standards associated with the information flows in your architecture – either the region or project architectures. If you are working on an ITS project, your should use the SET-IT software tool to create and customize a detailed project architecture which includes a Communications View. SET-IT’s Communications View allows you to customize and tailor full communications profiles for your project. Image description: A screen capture of RAD-IT Standards tab.

Capture Standards Information RAD-IT Tool Training June 2017 Capture Standards Information RAD-IT includes a list of communications standards imported from ARC-IT RAD-IT automatically maps these to your information flows Use Output / Tables and save them to Word or Excel While the “Standards” tab in RAD-IT 8.0 no longer provides the opportunity to directly decide which of the ITS Standards activities best applies to your situation you can use the Output Tables function to generate a listing of standards automatically from your information flows. To access this report use the Output Tables – Standards Activities, and Save the results to Word or Excel. From there you can customize the generated outputs to suit your region or project needs.  

Capture Standards Information – Cont. RAD-IT Tool Training June 2017 Capture Standards Information – Cont. For Project Architectures: Use SET-IT Tool to: Build Physical View Customize the service package diagram with elements and flows Use Communication View to review Communication Standards Create customized profiles to show all of the communications protocols and standards for each interface When you are developing a project architecture you should really use SET-IT to build the physical view (e.g. customized service package diagram with elements and flows) and then use the Communications View to review and customize the ARC-IT defined communications standards for each layer of the relevant communications profile.

RAD-IT Tool Training ITS Standards Groups June 2017 Combined set of standards that are common across many interfaces Profile used to show all communications protocols and standards for an interface Common groups in RAD-IT include: NTCIP Center-to-Center NTCIP Center-to-Field DSRC 5GHz Extensible Markup Language (XML) ITS standards groups were formed as a way of simplifying the presentation of a set of standards that are common across many interfaces. For example, rather than repeat a long list of standards for every applicable center-to-center information flow, a single group, “National Transportation Communications for ITS Protocol (NTCIP) Center-to-Center Standards Group”, was formed. With ARC-IT these also include the communications Profiles used in the Communications view. These are some of the common groups or profiles used.

Output - Standards RAD-IT Tool Training June 2017 From output tool bar you are able to produce outputs for a completed or partially defined Regional or Project Architecture. To view the Standards output for an architecture, you select “Output” then “tables” from the tool bar at the top of the RAD-IT window. This opens the output table window. You can traverse through the categories to find the Interfaces table under Interfaces and Standards Topics. Image Description: An image of the RAD-IT Output tool bar, with tables highlighted, is shown. A large arrow from the highlighted table selection points to a screen capture of a RAD-IT table dialog box.

Output Standards (Cont.) RAD-IT Tool Training June 2017 Output Standards (Cont.) Use the left arrow to select individual columns to include (they will then move to the Selected Columns table). You can also use the double left arrow to include all the columns. To view the report, you select the “Open Application” button in the Output Table window. The report opens in a new window from which you can view, print & save the report. Image Description: A screen capture of the RAD-IT Reports dialog box is shown, with a box around the “Open Application”. A large arrow points from the Open Application button to a screen capture of the preview of an agreements table.

Knowledge Check In the ARC-IT, ITS standards are mapped to: Subsystems RAD-IT Tool Training June 2017 Knowledge Check In the ARC-IT, ITS standards are mapped to: Subsystems Terminators Information Flows RAD-IT Tool In the ARC-IT, ITS standards are mapped to: Subsystems Terminators Information Flows RAD-IT Tool Time for a knowledge check. In the Arc-IT, ITS standards are mapped to: Subsystems Terminators Information Flows RAD-IT tool (Click to highlight the correct answer) The correct answer is Architecture Flows. ITS standards apply to communication which is represented in the National ITS Architecture as architecture flows.
