The Spatial Structure and Transportation
Six core concepts relates the spatial structure and transportation:
- Location implies the setting of a
system of reference (coordinate system) from which it is
- Distance is a measure of the friction of space when a
movement occurs and cannot be evaluated without at least two known
locations. This friction can be expressed according to several
such as length, time, cost, effort, energy or even the psychological
perception of distance as a deterrent.
- Fixedness. Since locations are fixed (absolute) disparities
are incurred, because economic,
social and political conditions change in space and time whereas
the geographical location remains the same.
- Attributes. All locations have different geographical
attributes. These attributes are the set of specific characteristics
that are relevant to a location, notably its resources. Population
can also be considered as a resource through the labor it
provides (qualifications and costs). The fact that different locations have different
attributes is an important factor behind the generation and attraction
- Relativity. All locations are relative since they must
be considered in a wider context and since a location is often
located by drawing reference to another. The importance of a location changes
with regards to its importance relative to other locations and to
the scale at which the comparison is made (local, regional or
global). The relative position
changes in time and with the development of activities.
- Dynamics involves three major issues. First, changes
at a location impact linked locations. Second, if a new link
is created, the importance locations bound to this link will change.
Third, whatever the nature of change, the effect will be positive
