Overview of Architecture

Statewide and Regional ITS Architectures

An intelligent transportation system (ITS) architecture is a high-level plan for how ITS can be used to address transportation needs in a state or region. An ITS architecture is required by the Federal Highway Administration (FHWA) and Federal Transit Administration (FTA) in order to use federal transportation funding on ITS projects. There are three key steps to developing a regional ITS architecture:

Step 1 Identify Needs and ITS Inventory
Stakeholder needs, as well as existing and planned ITS elements, are identified and documented.

Step 2 Develop ITS Market Packages (Services)
ITS market packages represent the services that ITS can provide to address one or more needs in a region. Market packages also show how that service will be operated and the data flows that will occur between agencies.

Step 3 Identify Sequence of ITS Projects to Deploy in the Region
The ITS deployment plan developed for each region identifies the projects that stakeholders recommended for deployment in order to implement the ITS services identified in the market packages.
