ABSTRACT
Narrow passageways are a significant source of
traffic congestion and delay in transportation
networks. With traffic volumes expected to increase
significantly in the foreseeable future, the effective
management of these passageways is needed to
mitigate the undesirable impact of these bottlenecks
on transportation system safety, performance and
cost. In an effort to address the significant challenges
associated with the analysis, design, and
implementation of appropriate management
operations for narrow passageways, an object-based
model for the management of narrow passageways in
the transportation network is developed. The
methodology proposed in this paper is a first step
toward end-to-end synthesis and validation of narrow
passageway of transportation systems. We formulate
a methodology that combines ideas from object-based
and systems-engineering development,and propose a
step-by-step procedure for transforming operations
concepts into a system-level design, and validating
behavior via formal modeling procedures.
