Definition:
The design is useful and marketable to people with diverse abilities.
Design Goals:
- Avoid segregation or stigmatization of any users.
- Provide the same means of use for all users — identical whenever possible; equivalent when not.
- Ensure privacy, security, and safety are equally available to all users.
Examples in Civil Engineering:
- Automatic doors at entrances allow both people with disabilities and able-bodied individuals to enter without assistance.
- Digital pedestrian signals with audio and visual outputs benefit both visually impaired and hearing-impaired users.
- Multi-height counters in public buildings or customer service points that serve people in wheelchairs as well as standing individuals.
Detailed Explanation
Equitable use emphasizes the importance of designing with all users in mind. It ensures that no one feels left out or singled out because of their abilities. This means providing options that are equally usable for everyone, whether they are in a wheelchair or able-bodied. For example, instead of just having steps to enter a building, an automatic door allows both wheelchair users and those who walk to enter easily together.
Examples & Analogies
Think of a restaurant that provides both braille menus for visually impaired customers and standard menus for everyone else. By doing this, the restaurant is ensuring equality in access to information and experience.

- Facilitate user accuracy and precision.
- Adapt to the user’s pace.
Examples in Civil Engineering:
- ATM machines with tactile keypads, audio outputs, and adjustable screen angles.
- Staircases with handrails on both sides to support left and right-handed individuals or people with reduced grip.
- Adjustable lighting in public spaces that helps individuals with varying degrees of visual sensitivity.
Detailed Explanation
Flexibility in use means that designs should cater to the different ways individuals prefer to interact with them. This could involve offering right or left-handed options, which is important for users who may not have the same strength in both hands. Adjustments in environments where people operate machinery or technology ensure that everyone can utilize these features effectively, depending on their needs and preferences.
Examples & Analogies
Imagine a kitchen designed with movable countertops. For someone who prefers to work standing up, they can adjust it to a higher position, while someone who prefers to sit can lower it. This flexibility makes the kitchen more usable for everyone.
