Using the Roadprint web-app tool satisfies Project Requirement PR-2 and may be useful for early planning and alternative development purposes. Alternate tools may also be approved for use but must do both energy and carbon footprint computations (not just one or the other). This tool uses a mostly USA and European (aging but high quality) dataset, which is used in most proprietary LCA tools. If you are not located in the USA, you can use this tool by selecting a state for your model with a best approximation of your local energy mix. Or, you can propose an alternate tool with verifiable/transparent data sources (no proprietary tools will be approved at this time) through the Project Certification process.
Roadprint is graciously hosted by Pavia Systems and was developed by the University of Washington for a FHWA Western Federal Lands research grant. Please note, Roadprint has no continued funding for support and WFL, Pavia, and UW do not provide help with the tool. However, it is free to use and measures the desired items for purposes of Greenroads Certification reliably. Greenroads staff can provide help for active project teams only that are Registered and pursing a Rating. Alternatively, if you want to help us make Roadprint better, you can consider donating or sponsoring this tool for it to be updated and maintained.
The LCCA Calculator Excel spreadsheet tool below can be used to compute the net present value (NPV) of a Project and user costs associated with different traffic management solutions during construction. Using this tool satisfies Project Requirement PR-6.
