A GEOGRAPHICAL ANALYSIS OF CHANGING REDUNDANCY IN INTER-URBAN TRANSPORTATION LINKS

The purpose of this paper is to investigate how closely real world networks tend through time toward the ideal postulated. A comparison of these networks can be made by utilizing a technique based on information statistics. These statistics enable the level of entropy in any network to be measured. By comparing the entropy of an ideal network with a real world network a statistical index of redundancy is obtained. This redundancy index indicates how closely real world networks approach the ideal. An application of the technique is presented for a regional network found in the greater Grey-Bruce area of southwestern Ontario. /TRRL/
