STUDY
AGENCY
Sacramento Transportation ARea NETwork (STARNET)
Needs Assessment
SACOG
DATE November 2001
The STARNET system design is based on an open and modular system
architecture that facilitates system and subsystem component integration
through standard communications interfaces.
PURPOSE
SUMMARY
Several meetings were conducted with the agencies who currently had
deployed transportation related systems within the Sacramento
metropolitan area. During these meetings, the goal was to collect
information regarding their hardware and software, as well as discuss
agencies’ goals and obj ectives relative to the sharing and exchange of
data/information within the region.
The following list summarizes the high-level needs for STARNET.
Ability to share cross jurisdictional signal timing data to improve
traffic flow
Ability to identify incidents which impact upstream/downstream
traffic flow
Ability to share video among agencies
Ability to centrally archive traffic volumes
“ This document has identified an architectural approach that essentially
centralizes the data processing activity and provides a uniform data and
control interface to the various stakeholders in the region. This is not
the only approach that could be followed. In other parts of the country,
agencies with similar goals to the STARNET stakeholders have opted for
system architectures that distribute the processing throughout the agencies
involved in a peer-to-peer configuration. While this type of an approach has
performance benefits and affords greater functionality for the user
community, it was deemed that such an approach for STARNET would
require unnecessary capital investment for the initial functional
requirements identified as part of this conceptual development process.”
