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?
