Evaluation of Highway Performance Measures for a Multi-State Corridor – A Pilot Study

Evaluation of Highway Performance Measures for a Multi-State Corridor - A Pilot Study

Determining an appropriate set of performance measures to use for managing the nation's highway network is a vital component of the work to preserve our existing transportation infrastructure. Recent research, such as National Cooperative Research Program (NCHRP) Project 20-74 describing an asset management framework for the Interstate Highway System (IHS), has highlighted the importance of establishing a consistent set of performance measures for communicating physical conditions of our roads, bridges, and other highway assets. The Federal Highway Administration (FHWA) Office of Asset Management developed this project to analyze bridge and pavement data across a multi-state corridor, evaluate the quality of existing performance measures, and recommend additional measures as well as further avenues of research in this area. A key deliverable involved using the Integrated Corridor Analysis Tool (ICAT), previously developed by the I-95 Corridor Coalition, as a platform to display bridge and pavement performance data. ICAT provides a map-based application, accessible via the Internet, that allows users to view, analyze, and compare performance data along an entire corridor or at a specific location. This project provides a statistical analysis of bridge and pavement data received from Virginia, Maryland, and Delaware. This analysis included looking at individual values as well as comparing values both within a state and across states.
