요약	A mixed-use index measures how evenly different land uses — residential, retail, office, civic, industrial — are blended within an area, turning the planning ideal of vibrant, walkable mixed-use districts into a number. The dominant formulation borrows the entropy measure from information theory: a value near zero when one use dominates and near one when uses are perfectly balanced. Popularised through the 'density, diversity, design' framework of Cervero and Kockelman and embedded in walkability indices by Frank and colleagues, these indices quantify land-use diversity for studies of travel behaviour, walkability and urban vitality.	Floor area ratio (FAR), also called plot ratio or floor space index, is the ratio of a building's total floor area to the area of the lot it sits on, and it is the workhorse metric of zoning-based density control. A FAR of 2.0 means a building has twice as much floor space as its plot, achievable as a two-storey building covering the whole lot or a four-storey building covering half of it. Embedded in zoning codes since New York's 1916 ordinance and analysed in planning texts such as Ben-Joseph's study of urban codes, FAR analysis quantifies development intensity, sets buildable limits, and links regulation to the form and density of the built environment.
