Here's a first pass at a new pattern.
Head Height Parity
People like to sit near pedestrian activity, but normal sitting height puts one uncomfortably low in relation to standing people.

It is not comfortable to sit with a standing person looming over you. In public places, this uncomfortable feeling compromises a lot of seating.
Overcoming this disparity in head height is commonly done two ways:
1. To define a piece of private space between the sitters and the standers, keeping the standers at a distance from the sitters so the sitter is not craning their neck to look up at the stander. This is one reason why a public bench recessed in an alcove feels better than one right on the sidewalk.
2. To perch on a higher than normal seat. At stool height, the sitter has rough head height parity with people standing nearby. Bars are prime examples.
A less common way to address this conflict is to raise the floor level of the sitting area relative to the adjacent walking area. This helps define the personal space mentioned earlier, and permits the use of normal height seating.
Head height disparity is particularly pronounced when people sit on the floor. Where floor sitting is the cultural norm, it is often the case that the sitting floor is raised several steps up from where people enter and circulate.
Therefore: Where sitting is adjacent to a lot of pedestrian traffic, adjust seating heights or floor levels to give sitting people roughly the same head height as standing people.
Comments welcome.
