Three case studies pertaining to the development of scientifically rigorous methods in urban
transportation planning are presented. Drawing on the lessons of these studies, an …

The class of simplicial decomposition (SD) schemes has shown to provide efficient tools for
nonlinear network flows. When applied to the traffic assignment problem, shortest route …

Models of traffic networks typically assume that the consumers of the transportation service
either behave in a totally noncooperative (user equilibrium) or cooperative (system …

Modeling of transportation systems must invariably balance behavioral richness and
computational tractability. In this paper, we develop a transportation equilibrium model and …

The concept of a spatial price equilibrium underlies most studies of spatial movement and
competition. However, this concept is based upon a notion of perfectly competitive markets …

We consider the two mode equilibrium road and transit assignment model which
incorporates a zonal aggregate mode choice model. We reformulate this special structure …

This paper discusses the use in logistics management of the freight network equilibrium
model, developed in Harker and Friesz (1985a, b), called the Generalized Spatial Price …

We show how to model combined mode-route choice and location-destination-mode-route
choice problems with interdependent travel impedances. Our models realistically extend the …

The complementarity problem is theoretically and practically useful, and has been used to
study and formulate various equilibrium problems arising in economics and engineerings …

This paper deals with the surveillance camera location problem in an urban transportation
network. In a bi-level model, it is intended to maximise route-flow observation in the upper …
