Establishing regional (and
national) standards for exchanging information among ITS deployments is
important not only from an interoperability point of view, but it also
reduces risk and cost since a region can select among multiple vendors
for products and applications. Standards allow competition, create
better products, and lower prices. Use of standards can also limit
product obsolescence and extend the effective life of an ITS investment.
A key to the success of ITS in
the Bay Area lies in the ability to exchange information between
systems. To be able to do this, however, requires the use of
communications protocol that can be understood at each end of the
transmission. Common protocols, such as NTCIP and eXtensible
Markup Language (XML) are required standards needed to exchange
information with major regional projects in the Bay Area. Additionally,
other required standards such as those for location referencing where
all systems can comprehend each other’s location referencing
system are necessary.
The Bay Area ITS Architecture
includes relevant and recommended standards for information exchange
(see Standards by Data Flow below) for most types of ITS
projects. The standards in the ITS Architecture serve as a
reference for how the interconnections operate for most types of ITS
projects. They are not technology specific and meant to provide a
functional overview of the interconnections. However, agency sponsors
should be aware that in some instances, there may be funding
requirements or regional policies that mandate use of project-specific
standards.
