Information Flows Updates
Turbo software was used to build the information flows and the interfaces. Various new flows and interconnections were identified.All the information flow diagrams were recreated and the operational concept for each of them revised and updated. Several new diagrams were also added to the website including information flow diagrams featuring interfaces from/to CapCOM, WMATA and VDOT VOIS (all new elements in the architecture).
A new internal frame was added to each element page to enhance readability of flow information.
Operating Concept Updates
VDOT has identified a separate task (Task D-3) for a NoVA-specific Concept of Operations (COO) Development.In addition to roles and responsibility statements in the Turbo Database, VDOT NoVA architecture also defined operational concepts by information flow diagrams. Each information flow diagram has a concept of operations associated with it on the website. Another source for concept of operations is the customized market package descriptions on the website.
A separate tab was added to the main menu called "Op. Concept" which leads to a page with a list of all the available information flow diagrams.
Functional Requirements Updates
Functional requirements are high-level descriptions of what each part of the regional ITS system must do. They are normally expressed as “shall statements”.To ensure readability, the “shall” statements are not provided on the website. They are available in the Turbo database where these statements can be viewed by element.
The website only lists the functional area and the functional area description
for each element at the bottom of the element page.
