Accessibility, entropy and the distribution and assignment of traffic--A comment

Abstract: In an article in this journal Erlander (1977) has suggested an alternative way of interpreting the entropy maximizing approach when used to derive the gravity model formulation for trip distribution. Erlander views the optimization model as a planning model and for this purpose examines two alternative formulations, which are referred to as the efficiency and accessibility problems. In this comment we point out the similarities and dissimilarities between these formulations and the derivation of the trip distribution model on the basis of conventional neoclassical utility theory. We also question the meaningfulness of interpreting the entropy maximizing framework as a planning model.
