Paper Title
Urban Composition: Case Study of Urban Planar Plots
Abstract
The goal of this study is to present a tool that permits to reduce the time of design and to obtain a quantitative
assessment of the urban composition. The model is based on the modelling of the functions and the corresponding spaces
into an orthogonal parcel having a planar form. The summation of all spaces that compose the parcel defines the surface
called plot surface. The space of road into the parcel is a correlation of the shape and of the disposition of the plots, and of
the number of plots in the urban Plan. The urban composition is characterized by a mathematical system composed by two
equations represented respectively by the urban density and the site coverage ratio. This system is indeterminate because
there is one unknown: the building footprint; and one correlation: the plot surface. To solving this problem, it is demanded to
introduce a value density random and one value that corresponds to urban size, and after to compare the density obtained
with the one introduced. This procedure uses the finite difference method. At last, the graphs illustrating the road ratio, the
urban features are presented, and some recommendations about the using of the urban land in according with the sustainable
development are proposed.
