Ramp - a transitional section of the road intended for exit or arrival on the main road. The term "ramp" is not used in Ukrainian and Russian normative literature, but is often used in technical literature and everyday life. Instead, the building codes use the term "congresses" ("left-turn congress", "right-turn congress"). Features of ramp geometry at multilevel transport interchanges: only one-way traffic; one or two lanes; the radii of rounding in the plan are much smaller than the recommended values for the main roads, respectively, and the lower design speed (design speed on some types of ramps can reach 80% of the speed on the main road); obligatory arrangement of turns.
