TRB’s National Cooperative Highway Research Program (NCHRP) Synthesis 422: Trade-Off Considerations in Highway Geometric Design describes the processes that transportation agencies currently use to evaluate geometric design trade-offs between competing interests.

The report also highlights existing key publications on conventional approaches, context-sensitive solutions/context-sensitive design, and performance-based approaches, as well as gaps in information or analysis processes available to support design decisions.
