Relative accessibility. Describes the degree of connection between any two nodes in a transport system, such as a seaport and an inland location. For instance, it can refer to the relative accessibility between port A and inland location B through port P by links 1 and 2.
Integral accessibility. Describes the degree of interconnection between a given node, such as a port, and all other nodes within a spatial network. On the figure, the integral accessibility of node 1 is a function of its foreland and hinterland connectivity.
Intrinsic accessibility. The potential to connect to selected hinterland markets is a function of infrastructure and transport service capacity. On the figure, each hinterland corridor (connection) has a distinct capacity of 1, 2, or 3.
Revealed accessibility. Reflects demand, such as actual traffic flows on specific hinterland corridors. On the figure, each hinterland corridor has a realized flow of 1, 2, or 3, which represents its actual use. This use is not necessarily proportional to transport capacity.
