Which design use is typical for an alignment?

• A. Road
• B. Building
• C. Parking Lot
• D. Garden

Answer: (A)

An alignment defines the horizontal path of a linear feature, providing the central route composed of tangents and curves. The most common use is for roads, where the centerline geometry guides the roadway design and drives the corridor modeling. This is why roads are the best fit: they require a precise, defined path to shape the pavement layout, transitions, and grading along a linear route. Building footprints, parking lots, and garden layouts are area-based designs that don’t rely on a centerline path in the same way, so they’re not the typical purpose of an alignment.
