A Multivariate Analysis Of The Space Syntax Output For The Definition Of Strata In Street Security Surveys

Although the connection between crime and urban layout is generally evident, surveys inquiring that relationship are often facing two different problems: areas with high criminality are often inhabited by partially elusive populations (being stowaways) and the urban structure (e.g. length and width of streets) quickly changes even after a few corners. In this work a combination of two techniques well known in their specific field is proposed to define a simple two-stages sampling design. Space Syntax is a set of measurements which are done on the topographic maps of a town with the division of all the roads into segments, called axes. Using multivariate techniques, these axes can be classified on the basis of a homogeneity criterion obtaining the strata for a two-stages sampling design
