Introduction
This wiki is designed to be a centralized platform to discuss and document the concepts and best practices found in every design manual related to American roadway design, including international guides. Some of the more notable sources for this wiki are the NCDOT Roadway Design Manual, AASHTO Green Book, NACTO Urban Street Design guide, and others. Being a wiki, this resource will also simplify the process of comparing guidelines when there are contradictions, either between manuals or within.
Railway, Airport, Waterway, and Structural Engineering may be added in the future.
