Three Views
Which one is best for you?

The choice of a view depends upon what you are looking for, and to some degree, your level of familiarity with the National ITS Architecture.

Hypertext View-
"Easy Navigation"

The hypertext view provides easy navigation through the various elements of the architecture, and is recommended for users just getting familiar with the architecture.  Using the hypertext architecture is also a good means to find all information pertaining to a specific application domain or subject of interest (such as Traffic Management), as the hyperlinks traverse across the various levels of the architecture.

The focus of the hypertext view is on architecture definition.  Other areas of the architecture, (e.g., Cost, Performance, Risk) are not included.  If your interest is outside of architecture definition, then you need to consider using the other views.

The hypertext view also contains a variety of key architecture graphics that you can easily copy and modify for your own use.

Document View-
"Everything About the Architecture – If You Know Where To Look"

The document view contains all the documentation for the National ITS Architecture.

If you’re looking for information pertaining to the origins of the National ITS Architecture, the processes used to develop the architecture, design objectives, implementation strategy, etc., this is the view to use.  Note that architecture definition can also be found in the documents, but this type of information is distributed throughout several different documents, so unless you are a seasoned user of the Architecture, it’s best to start with the hypertext view for this.

The document view also contains a wealth of graphics and tables that you can copy and paste into your own documents.  Be aware though, that these will be in bitmap format, which are not easily editable should you wish to modify them.

Database View-
"Access to Raw Data in Relational Tables"

The database view gives you access to the Physical and Logical architecture databases that contain the raw data used to develop and manage the National ITS Architecture.  With this data, you can develop your own architecture based upon a subset of the National Architecture.  A word of warning here!  Before using the databases to sort information or build your own tables, be sure that you understand the data relationships in the Physical and Logical architecture database tables.  It is recommended that only users accustomed to working with relational databases use this view to manipulate data.
