概要	A visual preference survey (VPS) elicits a community's design preferences by asking residents to rate a curated set of photographs — of streets, buildings, public spaces, and landscapes — on a simple numeric scale. Developed and popularized by planner Anton Nelessen, it turns the often vague question of what a community wants its environment to look like into comparable scores, revealing which images people reward, which they reject, and where they agree or disagree. The averaged ratings give planners a defensible visual brief grounded in resident preference rather than professional taste.	Placemaking evaluation is the structured assessment of whether a public-space intervention — a redesigned plaza, a reclaimed street, a new pocket park — actually makes the place more sociable, comfortable, and well used. Drawing on the observational tradition of William H. Whyte and Jan Gehl and codified by the Project for Public Spaces, it combines qualitative place-quality judgements with countable measures of activity, often comparing the same site before and after the change. The result is evidence that a place works for people rather than a designer's assertion that it should.
