Chapter 7. System Examples Departments of Transportation have
been learning how to develop telecommunications systems to
support traffic and freeway management for many years. There has
been a concerted attempt to create a standardized architecture
that would support requirements for most deployments. However,
one constant that has evolved is that no two systems can be
configured in the same way. Many elements (i.e.; modems, video
codecs, transmission media, etc.) of a communications system are
consistent in their functionality (system to system), but, it is
the unique arrangement of those elements that differentiates
between systems. Each user has their own set of requirements
which a unique (in overall design) telecommunications system is
required to support. This chapter will look at two very
different approaches to using telecommunications technologies
supporting freeway operations and traffic signal management: -
