Methodology
Area: New York City, Manhattan.
Period: 2015.
Unit of analysis: Street crossing.
Indicators:
Commercial rent - current year's market price of commercial real estate around a crossing in USD per square foot.
Commercial diversity - the number of unique commercial activities around a crossing.
Activity period - the active period of yellow taxi pick-ups from a crossing in hours.
Model:
3 filters control the diagram and the map through the range of values for each of the indicators.
3D diagram shows interrelation between the rent, diversity and activity.
Manhattan map shows the geography of areas with the selected characteristics.
Zoom-control and popup windows serve detailed analysis of specific areas.

Сhronotope city project explores the need for spatio-temporal coordination among commercial services / functions in densely populated urban environments. This need is clearly determined by commercial rent spikes in certain urban locations caused by their over-popularity.
