However, when applied to interchange ramps where high-speed facilities meet low-speed facilities and drivers are expected to accelerate or decelerate over short distances, application of the design speed process is more complex.The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 313: Selecting Ramp Design Speeds, Volume 2: Conduct of Research Report provides enhanced design guidelines for selecting appropriate ramp design speeds in a consistent manner, accounting for sequential speed transitions from one component or section to the next, consistent with performance capabilities of vehicles and driver expectations.Supplemental to the document are NCHRP Web-Only Document 313: Selecting Ramp Design Speeds, Volume 1: Guide and Ramp Speed Profile Model figures.
