Reducing Service Interruptions in Linear Infrastructure Systems (Transportation and Water/Sewer) by Synchronizing Schedules for Selected Maintenance Activities

Linear infrastructure systems (roads, water/sewer/power lines) are often interdependent due to the similarities in their design purposes to provide the necessary services. Hence, they are vulnerable to possible domino effects which can impact both the health and economic well being of communities. The key impacts of bottlenecks in interdependent linear infrastructure systems (ILIS) are reduction of system reliability and oscillations in service delivery capacity. In ILIS events are linked by time and dynamics of the interactions between the systems. This research will demonstrate quantitatively infrastructure limitations (design and operation) for coastal communities, identification of critical bottlenecks for service quality and propagation of domino effects in ILIS.

Objectives of this research are to:

1. Characterize service interruption profiles in ILIS;
2. Provide an dynamic analysis of interactions in ILIS;
3. Identify interactively the major events increasing the stress and service bottlenecks;
4. Develop an interactive tool to establish checkpoints for service quality.

The following tasks will be conducted during the study.
Task 1. Preliminary analyses
Task 2. Identification of service interruption hazard modes
Task 3. Profiling, classification and rating of hazard modes
Task 4. Service quality and priority assessment
