## What is an 

**ITS Architecture? **

## Driving Forces

**Legislative Provision in TEA-21**
- 	“The Secretary shall ensure that intelligent transportation system projects carried out using funds made available from the Highway Trust Fund, . . . conform to the national architecture, applicable standards or provisional standards, and protocols developed under subsection (a). ”
- 				-TEA-21 Title V, Sec. 5206(e)

## Two NPRMs and Request for Comment

- Transportation Planning NPRM  (§1410)
- Metropolitan and statewide planning (FHWA and FTA), including ITS Architecture and standards
- Project Development NPRM  (§940)
- National ITS Architecture and Standards (FHWA)
- Request for Comment
- Proposed Revisions to FTA Circulars (FTA)

- 90-day Comment Period

## Architecture and Standards Policy

- Three Key Parts:
-   Planning and ITS
-   Regional Architecture
-   Project Development

## Architecture and Standards Policy

- Planning - Intended Outcomes
-   ITS as part of transportation planning process
-   Wide range of stakeholders engaged
-   Future integration is planned
-   Work toward regional & national
-      interoperability

## Architecture and Standards Policy

- Planning - Proposed Regulations
-   ITS Integration Strategy developed as part
-    of transportation plan
-   Wide range of stakeholders engaged
-   Agreement developed on regional
-     operations & interoperability
-   Identify major ITS initiatives

## Architecture and Standards Policy

- Regional Architecture - Intended Outcomes
-   Integration is guided by regional architecture
-   Stakeholders agree on concept of operation
-   National Architecture is used as a resource

## Architecture and Standards Policy

- Regional Architecture - Proposed Regulations
-   Regional architecture is developed using the
-     National ITS Architecture
-   Regional architecture includes a concept of
-    operation and conceptual design
-   Regional architecture may be developed initially
-     or incrementally

## Architecture and Standards Policy

- Project Development - Intended Outcomes
-   System engineering principles are used
-   ITS projects provide for applicable info flows
-   ITS standards and interoperability tests are used

## Architecture and Standards Policy

- Project Development - Proposed Regulations
-   System engineering principles are used
-   ITS projects are consistent with regional
-     architecture
-   ITS standards and interoperability tests are used

## Architecture and Standards Policy

- What does this mean to Division Offices?
-   Customers need technical assistance
-   Stewardship role implications
-   Increased expertise level
-   Increased role of planning staff

## Architecture and Standards Policy

- What does this mean to Division Offices?
-   Are planners aware of ITS provisions?
-   What is an ITS integration strategy?
-   Who are the local stakeholders?
-   What kind of “agreement” is required?
-   What does a regional architecture look like?
-   What is the system engineering process?
