What causes urban mass micromovement flows? 2 factors extracted from RE :-)


Positional Utilites:

With activity specialisation, desires and fulfilment have become separated, as various needs are catered to by different locations. Micromovement is the means of correcting imbalances and inadequacies in desires and fufilment, i.e, when individuals have needs that cannot be met at their origin, they have to travel to a destination that presents the best compromise between fulfilling this need and minimising the distance travelled.



Topological Matrix:


The individual’s topological matrix is about his origin location(s) in respect to the larger urban structure and various positional utilities. The concept of an origin location refers to the location that the individual has to visit on a daily basis, and that which is relatively fixed and hard to change. The site and situation of these origins are obvious foci of the individual’s day-to-day life. In addition to Hurst’s idea of a topological matrix, we also put forth that this origin, while often being the individual’s place of residence, can also be his place of work, or other compulsively frequented places (e.g. a regular pub, a friend’s house etc.), or several of the above, in which case the individual places differing values on each, based on their importance or how easily they can be changed. Observe how origins, when separated by too great a distance, can shift to accommodate multiple origins, e.g. in the case of shifting house to live closer to place of work – which origin shifts, and which one stays, depends on the differing value the individual places on each.
