Why does SAD sometimes auto-adjust CSA boundary lines?

• A. To reflect weather patterns
• B. To rotate boundaries for aesthetics
• C. To simplify polygons in areas where no stop data exists
• D. To standardize all CSA sizes

Answer: (C)

When there’s no stop data in an area, the system auto-adjusts CSA boundary lines to keep the map sensible and usable. Without data to anchor a boundary, trying to carve out a precise, data-driven shape can create jagged, unreliable polygons. So the boundaries are simplified or merged with neighboring areas, reducing polygon complexity and ensuring each CSA remains a coherent, contiguous region that’s grounded in actual data availability. This isn’t about weather patterns, which aren’t tied to where stops exist, nor about rotating boundaries for looks. It’s also not about making all CSA sizes the same—the sizes naturally reflect data coverage and geography, and forcing standardization would distort how the data is represented.
