At the onset of any ITS project,
EPV establishes a project
methodology with the transit
agency; usually a phased
approach based on the ITS Project
Scope will be utilized. By
adhering to the FHWA–Systems
Engineering “V” Process
illustrated in the
diagram above, we are able to
plan and design any ITS
architecture before technology
choices are made. It also allows
for the development of
documented requirements to
support the system choices
recommended, integrated, and
ultimately validated.
Studies have shown that
utilizing system engineering and
following similar processes will
reduce risk, cost overruns and
meet the transit agency’s needs. Agencies should also consider
other success factors. It is
critical that any project have
management involvement in
addition to their support. Assembling a robust
implementation team will require
staff cooperation and buy in. The system selected should be field
proven and flexible enough to
handle existing and future
needs.
The basic project methodology
for any ITS projects, whether
provided by in house resources
or contracted to a professional
service firm, should consist of
at least three components. A
study of the organization’s
operation should be performed,
to assess requirements for a
Transit Management system. The
organization should apply the
results of their assessment to
develop a system procurement
process or verify the system in
place adequately fits their
needs. Once a system is
selected, the agency should
establish and monitor a
carefully structured
implementation process.
