Sacramento Transportation ARea NETwork (STARNET)
Needs Assessment
For new agencies, the following recommendations are presented:
New Agencies (with traffic operations system)
For new agencies with an existing Traffic Operations Center, it is also assumed that an existing video
switcher and viewing system is already in place. If the new agency has devices and traffic data it
would like to make available to the STARNET system, the Adapters and Device Servers (e.g., CCTV,
Signals, DMS) would need to also be developed.
New Agencies (device monitoring only)
For new agencies that desire only device monitoring, a PC capable of web browsing is needed. If
CCTV video-in-a-window viewing is desired, then there will need to be an ATM Network switch and
frame grabber hardware in the PC. If a system of digitizing the CCTV video and making it available to
the Internet is put in place, then the ATM switch and frame grabber would not be necessary to view
CCTV video within the web browser.
Backbone Communications
While not specific to a single agency, a significant commitment is required to support the
communications required for the STARNET deployment. As mentioned in this document, a preliminary
communications analysis must be completed early-on in the design phase to capture the available
options and summarize the costs / benefits associated with each approach. As part of the STARNET
Needs Assessment analysis for each of the participating agencies, an assumption was made that an
ATM communications backbone would be utilized. This was selected as a “ best-case” scenario for
system performance.
There may be other opportunities, which should be explored during the preliminary engineering phase
of this project, to solidify the communications aspect of this project. If budget considerations require
a less costly approach, the functionality of the system may be reduced. However, this must be
assessed as part of the detailed system design process.
