Object Modelling for the Management of Narrow Passageways in Transportation Systems

摘要

Within the transportation network arena, narrow passageways occur where the width of a transportation link is insufficient to permit operation of two-way traffic at normal speeds of operation. As a result, traffic congestion, accidents, and costly delays are common problems. The effective management of these systems is needed to mitigate the undesirable impact of these bottlenecks on 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, this paper attempts to develop an object-based model for the management of narrow passageway problems in transportation systems. The object model is formulated in two steps. First, we identify high-level management functionality, objects, and associated data/information sources that are common to all narrow passageway applications. In the second step, functionality of the object model is customized to the specific needs of the narrow passageway application domain (e.g., waterways).
