Many studies have been conducted to address the issue of population spatial mobility as a result of the growing transportation problems that many large cities are facing today. Space Syntax theory-based studies of urban mobility and transportation have focused on what Hillier refers to as the degree of predictability of the urban structure. The concept of predictability stems from the assumption that in every spatial configuration, each urban street has a potential attractiveness of journeys that depends on its integration with the overall street network. Thus, the degree of predictability of a given configuration is proportional to the degree of correlation between the prospective attraction for each street (as computed by its associated measure of topological integration) and the actual flows that reach these streets (measured in the number of pedestrians or vehicles). This index is derived a posteriori by performing a simple correlation calculation or a simple linear regression – ordinary least squares (OLS) between the topological degree of integration of each unit of the road system and the number of people or cars passing through through these pathways during a given period.
