ALDOT Statewide TSMO Program Plan ALDOT Statewide TSMO Program Plan 20190522REV | Page 41

The first step mentioned in the systems engineering process references regional architectures. This is a
process by which existing systems are defined and interoperability relationships within an agency are
identified. Recent upgrades and capabilities supporting connected and automated vehicles have been
added to the ITS Architecture software provided and required for use by FHWA. It is recommended that
ALDOT update the statewide ITS Architecture with current software ARC-IT, RAD-IT, and SET-IT.
The systems engineering process will guide project managers through each of the defined engineering
steps. Each of the ALDOT regional TSMO plans that have been prepared provide a basic systems
engineering framework recommended for use within that region. It is recommended that ALDOT consider
these frameworks and prepare high-level TSMO systems engineering guidance based on the type of
system being considered: existing system, existing system modification, new system deployment.
It is further recommended that a Statewide Configuration Management Plan and an Asset Management
Plan be developed and implemented. The implementation of standard configurations and asset
management will support consistent, efficient operations and maintenance of systems and allow for
greater optimization; realizing added value in existing and new systems throughout the state. In addition,
standardization of configurations and asset management will allow systems to be better secured.
