Rules Optimisation of density
Opening of temporary use of space : - Space "Day"
8h-19h
=> UB+UH+US
- Space "Night & Day"
8h-03h
=> UH+UA
GLOBAL DENSITY

FEELING DENSITY (Stay < 30mn)
REAL DENSITY (Stay > 30mn)

Neighborhood building links
Structuration of the site
Density "Night & Day" = (qUH*xUH*UH+qUA*xUB*UA)/Surface
Density "Day" =(qUB*xUB*UB+qUH*xUH*UH+qUS*xUS*US)/Surface
qi=Size of concerned population (i) xi=contribution(%) of i to temporary use of space
Density "Night&Day"
qUB - qUH - qS
Density "Day"
Density "Building"
