There is also a texture of activity in time: some areas are lively 24 hours a day, while others come to life for only a few hours, freezing for the rest of the time. There are places allocated entirely to one time of activity at all times of the day (hence the coarse -grainedness of the texture of the time), while in other Yudin the type of activity is sharply and suddenly replaced by another (fine -grained, rough texture) or, finally, various functions can exchange one another, smoothly superimposed (fine -grained, smooth texture). The same area can play the role of the vegetable market in the morning, the playground — in the afternoon, the places of adult meetings — in the evening — almost without interaction and even more conflict — due to the clarity of the borders of the transitions over time. Old and new, temporary or permanent can both coexist and contrast; and for temporary “granularity” the same considerations are true as for spatial: the subtlety of the texture gives significant advantages. Most highly appreciate places where contrasting form of activity easily and quickly replace one another, while the periodic desertness of spaces given to one activity of activity seems ineffective (however, confirmation of this requires special studies). Our urban planning is excessively focuses on spatial systems, practically ignoring their organization in time.
