The objective of this study was to develop a framework for integrated assessment of service vulnerabilities based on individual system failure probabilities, consequences, and potential interactions with other infrastructure networks. A comprehensive integrated network methodology was developed to evaluate and quantify the interactions between different infrastructure networks which included transportation and pipeline systems for water and sewer services. The quantitative risks were performed in terms of the individual network vulnerabilities, interactions of different networks (traffic, water, sewer), affected service areas, number of vehicles, and delays in transportation (vehicle hours) using ArcGIS. The interactive vulnerability and quantitative risk assessment methodology was demonstrated by applying for the transportation and pipeline systems infrastructure for the service area in downtown Miami, Florida.
