This section collects concrete examples of where "Good Sense" applies.

Select an example from the sidebar or browse below.

• Public transport end stations should start with different letters - People often remember only the first letter; ambiguity creates confusion.
• A transport line ID must never map to multiple routes - If variations exist, enforce explicit suffixes to avoid confusion.
• Use clear, distinguishable colors for lines - Avoid ambiguity and over-design. High contrast matters.
• Different transport modes should not share numbering systems - E.g. letters for metro, numbers for buses.
• Each platform must have a unique, consistent name - Use north/south, east/west, etc. — consistency over cleverness.
• If a street is too narrow, avoid cross-bus circulation - Prefer single-direction circulation where possible.
• Prefer straight corridors in buildings - Lower cognitive load, easier navigation, fewer surprises.
• Security access scanners should be on the right - Most people are right-handed; left-handed users already adapt.
• Prefer passive solutions over active ones - Lower failure rate, lower maintenance.
• Prefer functional solutions over aesthetic ones - A beautiful thing that doesn't work is trash. A working thing can be made beautiful.
• Prefer mechanical solutions over complex electronic systems - Electronics age poorly; mechanics can last decades.
• Use foot-operated mechanical systems instead of powered no-touch devices - Foot pedals never run out of batteries.
• When multiple toilets exist, keep left/right consistency across the building - Don't mirror layouts blindly; habit matters.
• Aircraft boarding: window seats first, aisle last; rear first, not last - Simple logic beats 'priority' groups for speed.
