Hierarchy of information - Template

These numbers are based upon the user testing, as well as our own interpretation. Qualities that determine an element's place in the hierarchy include text size, boldness, color, size and color of background box, as well as location within the sign.

It is important to note that this is a highly simplified interpretation. There are in effect at least two different hierarchical structures within the system - safety related and non-safety related (mainly cleanliness and communication).
