Greenroads: A Sustainability Performance Metric for Roadway Design and Construction
Greenroads is a performance metric for quantifying sustainable practices associated with roadway design and construction. Sustainability is defined as having seven key components: ecology, equity, economy, extent, expectations, experience and exposure. By Greenroads standards, a sustainable roadway project is one that carefully and overtly integrates these components into the design and construction process to a substantially higher standard than current common practice. Greenroads Version 1.0 consists of 11 Project Requirements, 37 Voluntary Credits (worth 108 points) and up to 10 points worth of Custom Credits. Project-level sustainability performance can be assessed by meeting all Project Requirements and any number of Voluntary Credit points. Greenroads also sets “achievement levels” at different point values in order to provide recommended scoring levels. Greenroads is compatible with other existing systems that can and have been applied to roadways and can be adopted in a number of ways, however, the most likely are: (1) as an external standard, (2) as a project accounting standard, and (3) as a tool for competitive advantage for both private industry and public agencies.
