COMBINED DISTRIBUTION, HIERARCHICAL MODE CHOICE, AND ASSIGNMENT NETWORK MODEL WITH MULTIPLE USER AND MODE CLASSES. IN: URBAN AND REGIONAL TRANSPORTATION MODELING. ESSAYS IN HONOR OF DAVID BOYCE

Abstract

This chapter on a combined distribution model is one in a book of essays published in honor of David Boyce for his contributions to the fields of transportation modeling and regional science. In this chapter, the authors present a combined distribution, hierarchical mode choice, and assignment network model with multiple user and mode classes. They formulated the problem as an equivalent mathematical program, which has been proved to satisfy all modeling requirements for the gravity-type distribution, hierarchical mode choice, and user equilibrium conditions of the multi-class problem. Evans' partial linearization algorithm is proposed to solve the resultant problem. The authors used the strategic transportation network in Hong Kong as a case study to illustrate the potential applicability of the proposed methodology for solving complex transportation planning problems. The authors also discuss the computing effort required for the proposed methodology.
