развязка; пересечение; транспортное пересечение; дорожная развязка(The correct general term for a road structure that manages multiple traffic flows at different heights (grade-separated) is an interchange (American English) or a grade-separated junction (British English). Overview of Terms: • Interchange/Junction: This is the umbrella term for a system of interconnecting roads (ramps/slip roads) that allow traffic to move between two or more major roadways without crossing traffic streams at the same level (at-grade). • Cloverleaf Interchange: This specific design features four loop ramps that resemble a four-leaf clover when viewed from above. It allows all turns between two crossing highways, but it has limitations (e.g., "weaving" issues) and has fallen out of favor for high-traffic areas. • Stack Interchange: This is a more complex type, often known colloquially as a "spaghetti junction" or "mixmaster," that uses multiple levels (often four or more) of direct or semi-directional ramps to handle high volumes of traffic with no weaving conflicts. This type of structure aligns more closely with the description of a single point from which many flows emerge, as it involves many overpasses and underpasses in a compact area. • Directional Interchange: This is the technical term for an interchange (like a stack interchange) where all left-turning movements are provided by direct or semi-direct connections that curve toward the intended direction of travel, rather than looping away from it.
