ACCESSIBILITY INDICIES FOR ABSTRACT ROAD NETWORKS

A measure of the accessibility of a point to other points in a region is the average over-the-road distance. Baxter and Lenzi (1975) examined the variation of such an index with the distance of the point from the town centre, for certain hypothetical road networks in a circular town. However, for a square grid network, they considered only the special case of a point on a road through the town centre. The object of this paper is to give results applicable to the general case, for a variety of homogeneous grid networks. It is shown that the appropriate result is obtained by multiplying the accessibility index for direct (air line) routeing by the route factor for the network concerned. /Author/
