This overview is the result of a collaboration of CITIES and Chunyan Song. Chunyan explored the density of the Randstad, a polycentric region in the Netherlands, Los Angeles, a metropolitan agglomeration in the U.S., and Istanbul, an emerging city in Turkey. The final product resulted in beautiful, eye-catching maps.

Global integration is about how one street relates to all others in a system. This system can be a neighborhood, a village, a town, or even a whole region.

Having accessible streets encourages diverse user groups, which leads to a stronger, more resilient economy. A global integration analysis shows where the most vital economic centers are or can be located.

Additionally, the structure of an urban street, determines the location of urban centers. If the street structure changes, the location of urban centers will change too.to calculate how spatially integrated a street is by looking at the total number of directional changes. In other words, a global integration analysis shows the degree of accessibility a street. The fewer directional changes, the higher accessibility (red). Conversely, streets with many directional changes lower (blue).
