3. Foundation for Requirements in RAD-IT
RAD-IT Tool Training
June 2017
Foundation for Requirements in RAD-IT
Defining high-level functional requirements for the inventory elements makes it clear just what the ITS systems need to do to deliver the ITS services. To select functional requirements of the ITS inventory elements in RAD-IT, the ITS elements need to be listed and the ITS services that they will provide should be identified. Inventory of ITS elements was discussed in module 5 and selecting ITS services in module 6 of this course.
Image Description: The diagram showing relationships between architecture components in RAD-IT is shown with the Requirements, Inventory and Services boxes highlighted.

4. Functional Requirements
RAD-IT Tool Training
June 2017
Functional Requirements
High-level descriptions of what an ITS element shall do in the region
Not detailed design requirements
Functional requirements deal with the ITS elements, or systems, not on the stakeholder (as in Roles & Responsibilities). In an ITS architecture, requirements are typically very high-level at the initial stage, then perhaps fleshed out more during a project definition phase.
Functional Requirements tell what a system (ITS elements) SHALL do.
For example, in the case of a State DOT TOC with closed-circuit television (CCTV) capabilities:
The system shall make CCTV camera images available to operational users
The system shall selectively provide access to camera control (pan, tilt & zoom) to operational users

5. Benefits of Defining Functional Requirements
RAD-IT Tool Training
June 2017
Benefits of Defining Functional Requirements
Identifies functions
What an ITS element must do to “hold up its end of the bargain”
Technology independent
Lays groundwork for more detailed specifications
Functional requirements document what ITS systems in the region shall do. The requirements do not specify how the system will perform the function; they do not specify what technology will be used.
Defining high-level functional requirements lays the groundwork for defining detailed specifications when a project is to be deployed.

6. Functional Requirements Needed
RAD-IT Tool Training
June 2017
Functional Requirements Needed
For regionally significant ITS elements
Traffic Management, Transit Management, Emergency Management, etc.
Not for non-ITS systems that interface with ITS elements
National Weather Service, etc.
Not all elements in your inventory require functional requirements to be defined. Requirements should be defined for the ITS elements whose functionalities are significant to the region and for those that stakeholders will be deploying in their ITS projects.
It isn’t necessary to define requirements for the non-ITS systems that interface with your ITS elements such as the National Weather Service.

7. Requirements Tab RAD-IT Tool Training June 2017
To enter functional requirements, select the seventh tab from the left on the RAD-IT interface, labeled Requirements.

Selecting Functional Requirements in RAD-IT
Select functional Objects for ITS elements
based on each element and their mapping to physical objects and services
Select functional requirements
based on each functional objects
Step 1
Step 2
Selecting functional requirements in RAD-IT is a two step process.
Step 1 is to select functional objects for each ITS element based on the physical object mapping of the element and the ITS services in which it is involved.
Step 2 is to select actual requirements of the elements involved in the functional object.
Let’s look at the steps in more detail.

9. Selecting Requirements
RAD-IT Tool Training
June 2017
Step 1
Selecting Requirements
Two options to select functional objects for an element:
Select functional objects manually OR
Allow RAD-IT to select functional objects based on ITS service selections
There are two options to complete the first step of selecting functional objects in RAD-IT. For each ITS element that needs functional requirements, you may either select functional objects manually or let RAD-IT select an initial set of functional objects based on the ITS service selections.

10. Selecting Requirements (cont.)

Step 1
Selecting Requirements (cont.)
Two Display Options
Autoselect
Functional Objects (FO)
The Requirements tab can be displayed in two ways. It can be based on elements or functional objects by selecting the appropriate tab on the right side. Let’s look at the element view first. We’ll look at the Functional Objects view on the next slide.
(Click to display arrows.) In the element view, elements are listed on the left side. For the selected element, functional objects (which are known as functional objects in the RAD-IT) and their description and associated Physical Object and its type are listed on the right.
(Click to display circle.) To manually select functional objects for an element, select the element then select the “Specify Functionality” button which will allow you to select the desired areas.
(Click to display circle.) To have RAD-IT recommend a preliminary set of areas based on the ITS services selections, use the Autoselect button. We will look at the Autoselect process after looking at the functional objects view for the Requirements tab.
Image Description: A screen capture of RAD-IT with a large arrow pointing to the Elements pane within the Requirements tab is shown. Text reads “Two Display Options” leads to the Elements and Functional objects check boxes with an arrow. The image is further annotated with text and arrows identifying the functional objects check boxes, the Functional object description text field, and the Associated Physical Objects and its Type text field. An oval highlights the Specify Functionality check box, and the Autoselect button is highlighted with a box.

Step 1
Selecting Requirements (cont.)
When the Autoselect button is selected, the Autoselect Functional Objects window opens. There are two settings for Autoselect:
Functional Objects can be selected for all elements of the current architecture or only for the selected element.
Functional Objects that support the selected services can be added and/or the Objects that don’t support the selected services can be deleted.
Once the settings have been set, you select the Continue button to perform the Autoselect.
Image Description: A screen capture of the first Autoselect Functional Objects dialog within RAD-IT is shown. Radio buttons to select between the entire architecture or just for the selected element are annotated with text and a curly braces. Check boxes for adding and deleting functional objects are also annotated with text and a bracket.

Step 1
Selecting Requirements (cont.)
No Functional Objects yet identified
Icons on the Requirements tab reflect which elements have functional objects selected. In the Elements view, a yellow folder icon signifies that an the element does not have any functional objects selected. When functional objects have been selected the icon changes to the blue “f” icon.
Image Description: A screen capture of RAD-IT is shown with the Requirements tab selected. The image is annotated to identify a blank rectangular icon in the Elements list as indicating no functional objects yet identified. The image is further annotated to identify an icon with an “f” in the Elements list to as indicateing that functional objects have been selected.

Step 2
Selecting Requirements
Requirements
Once functional objects are selected, specific functional requirements can be selected. Functional requirements must be manually selected. The Autoselect feature does not select any requirements, only functional objects. However, unlike the roles and responsibilities of an Operational Concept, functional requirements do not have to be written from scratch as RAD-IT contains the functional requirements from the ARC-IT which can be selected for elements.

Selecting Requirements (cont.)
ITS element
Functional Objects
When the Requirements button is selected, the Functional Requirements window opens. In the window, you can select the ITS element and Functional Object for which to display requirements.
(Click to display boxes.) There are two options for tailoring the display in the Functional Requirements window:
The Limit button limits the display to the requirements that are selected
The Sort button allows the requirements to be sorted three ways: by number, by include or by status.
The Functional Object and reference number of each requirement from the ARC-IT are given. To select a requirement, you can select the Include box or change the Status to other than “Not Planned”. The Tailored column cannot be modified as it is just an indicator of which requirements are not from the ARC-IT but were defined by the user.
(Click to display arrows and text.) To add a completely new requirement, select the new button. To modify an existing requirement, select the Tailor button which will add a copy of the selected requirement that can be modified. Let’s look at how a requirement is tailored.
Image Description: A screen capture of the Functional Requirements dialog within RAD-IT is shown. The image is annotated with arrows and text to identify the ITS element and Functional Object pull-down selection lists, the Limit and Sort buttons, columns in the requirements list showing status and whether the requirement is included and/or tailored, and the New and Tailor buttons.
