TRANSPORTATION
AND CHANGE
Our transportation system
provides fundamental and
basic services to society, and
has done so for thousands of
years.
‹ However,
as we begin the
21st century, the field is
subject to many changes.
‹ These transitions occur on the
dimensions of technology,
systems and institutions and
characterize the field in its
broadest sense.
TRANSITIONS
‹
What are these transitions?
‹
What do they mean for the
education of the “New
Transportation Professional”?

COMPLEXITY
Complexity as in CLIOS
(Sussman, “The New Transportation
Faculty: The Evolution to Engineering
Systems”, Transportation Quarterly,
Summer 1999):
‹ A system is complex when it is composed
of a group of related units (subsystems),
for which the degree and nature of the
relationships is imperfectly known. Its
overall behavior is difficult to predict, even
when subsystem behavior is readily
predictable. Further, the time-scales of
various subsystems may be very different
(as we can see in transportation -- landuse changes, for example, vs. operating
decisions).
