Objectives of this study is to develop a framework for evaluating service vulnerabilities based on individual system failure probabilities and overall impact on traffic flow to identify:1. Similarities in service interruption profiles in linear systems
(transportation, water/sewer);
2. How service failure events relate to one another in infrastructure networks;
3. How maintenance schedules can be coordinated to reduce service interruptions and reduce maintenance costs.
Case study: Quantitative risk analyses were conducted for the impacts on transportation network due to pipeline network failures in water and sewer utility lines.

ConclusionsA quantitative risk assessment methodology was developed for estimating vulnerability and impacts for linear infrastructure networks (traffic, water and sewer pipelines).
Mapping of pipeline networks which can impact the traffic network based on service failure allowed identification potential vulnerabilities on traffic flow.
Spatial analyses using ArcGIS allowed visualization of the vulnerable areas, areas with different levels of vulnerabilities, and quantification of the potential impacts (i.e., area, number of people, traffic delays).
The methodology can be used as a management tool for allocating resources to reduce the service interruptions.
Integrated analysis of infrastructure networks is an effective tool for smart maintenance planning to improve service quality and reduce maintenance costs.
A multilevel quantitative risk assessment methodology was developed to quantify the impacts on transportation networks due to pipeline failures (i.e., water and sewer). Vulnerability of the service networks for transportation and pipelines systems were identified based on failure characteristics of each network as follows: Failure probabilities of water and sewer systems and the effects on
the transportation were analyzed using ArcGIS. Affected service areas, number of vehicles, and delays in
transportation (vehicle-hours) were quantified for a case study area located in downtown Miami, Florida.
Impacts on traffic flow were evaluated by segmentation based on the node based connections and visualized by ArcGIS.
Annual average daily traffic (AADT) data was used to assess the traffic impacts for affected links.
Consequences of service failures were quantified and visualized by integrating failure data into ArcGIS to estimate the traffic impacts.
