Information Design for Public Systems
Designing for transit, health, and civic systems that everyone must use.
Public systems, transit networks, health information, civic services, must be usable by everyone, including people under stress, with low literacy, or unfamiliar with the system. This course covers designing for universal comprehension in high-stakes, mandatory-use civic contexts.

LEARNING OUTCOMES
- 01 Explain why public systems demand a higher usability bar than optional consumer products
- 02 Design for users under stress, low literacy, or unfamiliarity with the system
- 03 Apply plain-language principles to civic and health information
- 04 Design transit and wayfinding information for diverse, non-expert populations
- 05 Evaluate a public information system for equity of access across ability and language
- Mandatory-use systems carry higher stakes for failure
- Users cannot simply abandon a confusing public system
- Stress reduces comprehension capacity measurably
- Design for the stressed user, not the calm one
- Text-only systems exclude significant portions of the public
- Pictorial cues supplement, rather than replace, textual information
- Plain language benefits every reader, not just low-literacy ones
- Jargon in civic communication is a design failure, not a neutral choice
- Transit systems serve radically different user types at once
- Optimising only for daily commuters excludes first-time and visiting riders
- Equity audits look beyond the median user
- A system that works for most people can still fail vulnerable groups badly
