摘要：

The objective of this paper is to evaluate the usefulness of the weighted l(p) norm as a distance measure when axis rotation is included to obtain the best fit. We compare the weighted l(p) and Euclidean norms in an empirical study of 18 major country and city road networks. A substantial improvement in accuracy is obtained with the weighted l(p) norm for networks with a significant component of rectangular travel. We show that the weighted l(p) norm, and by inference other multi-parameter distance estimators, are justified in practice provided the reference axes are oriented properly to model the directional bias inherent in the network.
