Seismic Vulnerability of the Highway System

Task B1-2: Support and Extensions for Review of ROAD-1
Seismic Risk Analysis Software
Subject Area: Loss Estimation Methodologies

Principal Investigator(s) and Institution(s)
Stuart D. Werner, Seismic Systems & Engineering Consultants

This task is part of the overall project effort being carried to develop loss estimation methods for highway systems. This effort will build on the methodology for seismic risk analysis (SRA) of highway systems that was developed under FHWA/MCEER Project DTFH61-92-C-00106, by extending and incorporating new loss models into the economic module of the SRA methodology. The initial phase of this work will consist of an independent review under Task B1-1 of the software previously developed (currently called ROAD-1), which is the beta software developed to implement the SRA methodology. This task will support the independent review by assisting in resolving questions that may arise and providing guidance on the operation of the methodology and software. In addition, to facilitate this review, this task will implement and document a demonstration application of ROAD-1 to the analysis of the Memphis, Tennessee regional highway system.

This task will consist of the following subtasks:

Subtask 1 - Support of SRA Review. The team that developed ROAD-1 will be available to the reviewers of the software working under project Task B1-1, to address questions that may arise and assist in the evaluation and assessment.

Subtask 2 - Demonstration SRA. The latest version of ROAD-1 will used in a demonstration analysis of the Memphis, Tennessee regional highway system. The purpose of this analysis is to provide the Task B1-1 reviewers with detailed documentation of an actual application of the ROAD-1 software package, and to facilitate its review and evaluation.
