Methods of Analysis

Two measures of urban layouts that PLACE LOGIC can analyse include Street Activity and Place Connectivity. These measures provide different but complementary insights to how places function at various scales.



Street Activity


Street Activity measures the relative importance of intersections for travelling through a network.

It provides a representation of the number of times we would use an intersection if we were to travel along the shortest path from each intersection in the network to every other.

To allow for clearer representation, routes adopt the average value of the two intersections that define them, and the level of activity of route within a network is exhibited using a colour scale.

The most active routes appear in red, whilst the least active appear in blue.


Examples of applications:

  • Commercial valuation
  • Crime and security
  • Urban space and public realm design
  • Street hierarchies and landscaping





Place Connectivity


Urban centres tend to be located on well-connected intersections.

Place Connectivity measures the average distance between an intersection and every other intersection within the whole network, or a defined radius (i.e., a 15 minute walking radius of 1200m).

As in the case for Street Activity, routes adopt the average value of the two intersections that define them to allow for clearer representation.

Likewise, Place Connectivity outputs are presented using a colour scale whereby the most connected routes are shown in red, and the least connected are shown in blue.


Examples of applications:

  • Landuse distribution and density
  • Location of commercial centres in large developments
  • Location of civic functions and other key facilities
  • Land valuation
