Document Summary
Distance decay: the declining intensity of any pattern or process with increasing distance from a given location. And other tangible commodities between the different nodes of the city along transportation channels. Delivery trucks or trains taking raw materials or finished products to factories or stores along roads or railways. Commuters going to and from work using roads or subways. Migration of people (and their things and their cultures) from outside your city or country to inside your city or neighbourhood. Non-physical flows are the transmission of more intangible commodities such as information between nodes along sometimes less visible transmission channels. Collectively, these flows are known as spatial interaction. This is an integral part of both your life. Also to the life of the city. It is essential to its growth, functioning, and survival. Form and pattern are often the result of spatial interactions. Allows integration of spatially separated parts of the city. Allows differentiation and specialization within the system.
