Building on Whyte’s work on livable places, the present study developed a four-item scale to assess visitability and used it to test whether three attributes identified by Whyte—seating, food, and triangulation—increase visitability. The study used color slides of three plazas altered for the presence or absence of each attribute. Sixty participants (23 men and 37 women) rated slides of the plazas on each of four items on the Perceived Visitability Scale (PVS). The four items had high interitem reliability, and each item and their composite had high interobserver reliability. The visitability ratings showed that plazas with seats, food, or sculpture had higher scores than plazas without those elements; and the combination of seats and sculpture had higher scores than either element alone. Contradicting Whyte, there was no statistically significant effect of gender. Seats, sculpture, and the perceived compatibility of elements with one another may improve plaza visitability.
