| Abstract: | A number of measures of accessibility are applied to the road and transport networks of the N.W. Highlands and Islands. The concept of ‘accessibility’ is interpreted at the regional scale and in a physical, rather than a behavioural, sense. Although other indices are briefly mentioned, three basic approaches are examined in greater detail: travel timings from a central point, shortest paths through the network between every pair of nodes, and potentials. From all the methods discussed, there is a large degree of consensus on the spatial patterns of accessibility in the region. |
