Which layout is described as allowing for increased walking distance due to movements in and out?

The U shape layout is characterized by its design that allows for increased walking distance due to the nature of its configuration, which involves two parallel lines or sides that curve back towards each other. This design can create longer distances as individuals move between different sections of a space, engaging in activities or accessing various areas. The U shape fosters interaction and flow, often facilitating social exchanges while also requiring more movement from one space to another.

In contrast, straight line layouts typically promote direct paths that minimize distance and can streamline movement, while L shape layouts can create corners that might limit traffic flow or increase short turns. A parallel layout also focuses on more streamlined access, usually encouraging a straightforward and efficient movement pattern. All these other layouts generally do not provide the same degree of increased walking distance related to movement in and out as the U shape does.
