Take advantage of FHWA's investment in the National ITS Architecture, training, and technical assistance to minimize the effort required to develop a Regional ITS Architecture.

When defining the ITS regional framework and architecture, the planners should take advantage of FHWA's investment in the National ITS Architecture, supported training, and technical assistance to minimize the work effort and streamline the decision-making process. The planners should schedule/conduct workshops to educate
stakeholders on the National ITS Architecture (and its components) and the Regional ITS Architecture (and its deliverables).

When developing the Regional ITS Architecture, stakeholders should consider undertaking the
following tasks:

• Map existing systems and connections to the National ITS Architecture

• Group selected Market Packages into subsystems and map to the National ITS Architecture

• Identify and classify connectivity between subsystems

• Review individual Market Package Architecture Flows and tailor to the region/state

• Tailor connections between subsystems to reflect actual agency relationships (i.e., Organizational Architecture)

• Identify appropriate ITS Standards and status of development activities

Regional ITS Architecture deliverables should be agreed-upon prior to project initiation and specifically identified through agency MOUs and/or consultant contract/SOW. The Regional ITS Architecture for a large geographic area needs to be developed at a level of detail appropriate for the budget, and the understanding that further deployment efforts may be needed to enhance the base architecture.

These actions improve the efficiency of development of the Regional ITS Architecture.
