Architecture Maintenance Page

Updates to the Austin Regional ITS Architecture will occur on a regular basis to maintain the architecture as a useful planning tool. Between complete plan updates (scheduled to occur every four years), smaller modifications will likely be required to accommodate ITS projects in the Region.

For situations where a change is required, an Architecture Maintenance Documentation Form was developed and is included in Word format below. This form should be completed and submitted to CAMPO whenever a change to the Regional ITS Architecture is proposed.

The Architecture Maintenance Documentation Form identifies three levels of modifications. They include:

  • Level 1 – Basic changes that do not affect the structure of the architecture. Examples include: Changes to stakeholder or element name, element status, or data flow status;
  • Level 2 – Structural changes that impact only one agency. Examples include: Addition of a new market package or modifications to an existing market package that affects only one agency; and
  • Level 3 – Structural changes that have the potential to impact multiple agencies. Examples include: Addition of a new market package or modifications to an existing market package that involves multiple agencies or incorporation of a new stakeholder into the architecture.

In the process of documenting the change, the stakeholder proposing the change should contact any other agency that will be impacted by the modification to obtain feedback. This communication between agencies will simplify the process of performing a complete plan update. CAMPO will review and accept the proposed changes. When a complete update is performed by TxDOT, all of the documented changes will be incorporated into the architecture.
