TRB's National Cooperative Highway Research Program (NCHRP) has released a pre-publication, non-edited version of Research Report 855: An Expanded Functional Classification System for Highways and Streets. This report builds upon preliminary engineering of a design project, including developing the purpose and need. In particular, it provides additional contexts beyond urban and rural, facilitates accommodation of modes other than personal vehicles and adds overlays for transit and freight. Two case studies illustrating application of the expanded system to actual projects are included.
