概要	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.	A walkability index measures how well a neighbourhood's built environment supports walking, by combining a small set of land-use and street-design variables into a single score. The influential index developed by Lawrence Frank and colleagues sums standardized measures of residential density, land-use mix, street connectivity, and retail floor-area ratio, giving extra weight to intersection density because connected street grids most strongly enable walking. Consumer tools such as Walk Score popularized the same idea by scoring an address on the proximity and variety of nearby destinations, making walkability a routine input to planning, public health, and real-estate analysis.
