Parking signage
Background
User Personas
For this kind of project, which did not contain many moving parts, I decided to conduct some A/B testing. I was looking for the most efficient way the negation (“No Parking”) could be communicated. As a foundation for my user testing, I developed some metrics that would hold my iterations accountable.
User Testing

Can the user correctly read the sign aloud as a sentence?
Given the signs are designed to be verbally coherent—regardless of the user’s language—users reciting the sign’s content proves it is comprehensible.
How long does it take the user to answer?
For software, the Doherty Threshold stipulates that latency of longer than 400ms make the user feel delayed. When prompted to answer as quickly as possible, I’ll use a slightly longer metric of 3 seconds to determine if the user can read the sign “at a glance”.
Does the sign make the user feel confident parking in this space?
It is critical that the user have a positive feeling regarding their decision to park, as this is a factor in a rewarding user experience.
