Permeability - shaping how people move within cities

Permeability and crowdsourcing

Permeability is defined by the ability of the urban tissue to offer different routes, through and within it and measures opportunity for movement. Accessibility is a product measure of permeability; it is actually the product of the individual and the cadastral system the cadastral street patterns which is the layout of urban blocks shows the public space network and pinpoints pain areas that are blocking permeability in an urban area.

By defining the spaces that define the blocks ,we can analyze the nature of the tissue of the development.
By analyzing the tissue, we can understand better the relationship between the buildings and the space around them; this relationship will give us insight on their permeability.

Visual permeability is the availability of vistas, which are the views corridors in a tissue

Physical permeability represents the ability to seek different routes .
The measure of permeability is the degree of the grid texture; finer grid permits higher visual and physical permeability than coarser grids.

Symbolic permeability links essentially to the mental map of the city for its visitors and residents-
it is the amenability of its tissues for new imprints-
new crowd courcing techniques are rewriting the way permeability has been deisgned - the sheer volume of information relating to how citizens view their city permeability means that designers ,urban planners and policy makers may be more and more challenged - 

NYC launched a competition last year AND GUESS WHO WINS- A WAY FINDING APPLICATION -this gives a real indication that permeability is one of the most important quality that citizen look in cities because it is what helps moveand experience its spaces.would be interesting to see what types of urban information such application might tell us ?
