Operating Concept
Stakeholders |System Inventory | Market Packages | Entities | Operating Concept
An operating concept is a high-level description of an ITS system that
emphasizes the roles and relationships of key stakeholders. It summarizes
the "big picture", showing major system elements and their general
relationships in the long-term (10-year) view.
The VDOT NoVA Operating Concept is presented in three drill-down levels
with each successive level providing greater detail. This organization allows
users with varying needs for detail to view the operating concept at whatever
level best fits their needs and perspectives.
Tier I - Program Areas:
This tier provides the highest level understanding of NoVA ITS operations such as may be useful for policy-makers and non-transportation audiences. The NoVA Operating Concept consists of three "program areas" Systems Operations, Regional Emergency Management, and Traveler Information.Tier II - Activity Areas:
This next-level is appropriate for NoVA ITS stakeholders in that it identifies their roles and responsibilities and how they relate to other stakeholders in specific activities like electronic toll collection, incident management etc. Under each activity area, several information flow diagrams are provided.Tier III - Market Packages:
The final, most detailed level of the NoVA ITS Operating Concept, Tier III, consists of the market packages associated with the NoVA region. Market packages represent slices of the ITS Physical Architecture that address specific services like broadcast traveler information, HOV lane management, surface signal control, etc. A market package encompasses several different subsystems, equipment packages, terminators, and architecture flows necessary to provide a given ITS service.To begin accessing the operating concept, click on any of the three Tier I program areas in the graphic below.
