Description: TRB's National Cooperative Highway Research Program (NCHRP) Report 687: Guidelines for Ramp and Interchange Spacing explores guidelines for ramp and interchange spacing based on design, operations, safety, and signing considerations.     The report is designed to help aid the decision-making process when an agency is considering new ramps or interchanges on existing facilities, modifying ramps and interchanges of existing facilities, or when planning and designing new highway and interchange facilities. The guidelines also offer standardized definitions measuring ramp and interchange spacing, which have varied in previous design guides.     A final report documenting the full research effort related to the development of NCHRP Report 687 was published as NCHRP Web-Only Document 169--
