Series Editors Manfred M. Fischer Geoffrey J.D. Hewings Peter Nijkamp Folke Snickars
This series contains scientific studies focusing on spatial phenomena, utilising theoretical frameworks, analytical methods, and empirical procedures specifically designed for spatial analysis. Advances in Spatial Science brings together innovative spatial research ulilising concepts, perspectives, and methods relevant to both basic science and policy making. The aim is to present advances in spatial science to an informed readership in universities, research organisations, and policy-making institutions throughout the world.
The type of material considered for publication in the series includes: Monographs of theoretical and applied research in spatial science; state-of-the-art volumes in areas of basic research; reports of innovative theories and methods in spatial science; tightly edited reports from specially organised research seminars.
Sven Erlander Cost-Minimizing Choice Behavior in Transportation Planning
This book stems from a desire to understand the underlying assumptions and structure of the choice probability models most often used in Transportation Science. The book investigates how far a new way of defining cost minimizing behavior can take us. All commonly used choice probability distributions of the logit type - log linear probability functions - follow from cost minimizing behavior defined in the new way; sorne new nested models also appear. The new approach provides a deeper understanding of what is at work in the models. The new way of defining cost minimizing behavior is as follows: cost minimizing behavior pertains if the likelihood (probability) of any independent sample of observations is a decreasing function of the average cost of the sample. Extreme value distributed random variables are not used in the derivation of models. A measure of freedom of choice related to the Shannon measure of how much "choice" is involved is used to obtain a welfare measure which is equal to composite cost.
