Asset Sustainability Index: Quick Guide. Proposed Metrics for the Long-Term Financial Sustainability of Highway Networks

摘要

This report provides a Quick Guide to the concept of asset sustainability metrics. Such metrics address the long-term performance of highway assets based upon expected expenditure levels. It examines how such metrics are used in Australia, Britain and the private sector. It also reviews asset management data from selected states to illustrate that long-term sustainability metrics could be produced using available U.S. asset management data.
