What is the term for a set of lanes at an intersection that accommodates all left turn, through, and right turn movements?

The term used to describe a set of lanes at an intersection that accommodates all left turn, through, and right turn movements is "Approach." This term refers specifically to the roadway section that leads to the intersection itself and includes the various lane configurations necessary for drivers to execute their intended maneuvers safely and effectively.

Each lane within the approach is designated for specific movements, such as left turns, through movements, and right turns, allowing for organized traffic flow and reducing the potential for conflicts between different turning movements. By clearly defining these lanes, an approach facilitates smoother transitions across the intersection and enhances overall traffic operation.

The other options provided do not capture this specific functionality. For instance, "Intersection Layout" generally pertains to the overall design and arrangement of various components at the intersection, rather than focusing solely on the lanes leading up to it. "Turn Lane Configuration" might suggest the arrangement of lanes specifically meant for turns but does not encompass through movements. "Crossroad Design" implies a broader focus on the design of streets crossing each other, without specifically referring to the approach leading to an intersection. Therefore, "Approach" is the most accurate term for the set of lanes accommodating diverse traffic movements.
