Network Aggregation in Transportation Planning. Volume II: A Fixed Point Method for Treating Traffic Equilibria.

摘要

Volume 2defines a new algorithm for the network equilibrium model that works in the space of path flows and is based on the theory of fixed point method. The goals of the study were broadly defined as the identification of aggregation practices and the development of a framework for studying these practices. These goals have been accomplished by, (a) conducting a survey of aggregation practices, (b) formulating an aggregation model, (c) conducting a computational study, (d) deriving mathematical programming formulations aimed at making steps of the model precise,and (e) programming and testing a particular algorithm.
