Modern cities are running on performance indicators. They move millions of people each day, concentrate capital, separate land uses, and sustain complex systems of logistics and consumption. In that sense, the city functions as a system to be continually adjusted and optimized.
Today's dominant metrics are familiar and widely witnessed: vehicles per hour, average commute times, floor area ratios, parking turnover, housing starts, and tax revenue per parcel of land. These figures describe a city that is legible through efficiency. They are inherited from an industrial logic, where urban space is treated more like a production mechanism than a lived-in environment. In this framing, cities begin to mimic the needs and metrics of a machine.
