Zusammenfassung	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.	The urban vitality index is a composite descriptive measure of how lively, busy and economically active an urban area is, built from the conditions Jane Jacobs argued generate street life. In The Death and Life of Great American Cities (1961), Jacobs identified four generators of diversity — mixed primary uses, short blocks, a mix of building ages, and sufficient density — together producing the foot traffic and 'eyes on the street' that make places vital. The index operationalises these qualities as measurable indicators for each spatial unit, normalises them onto a common scale, and combines them into a single vitality score that can be mapped, compared and tracked over time.
