In the past 10 years increased importance has been placed on public participation and
environmental concerns in transportation system decision-making. While there are …

Two recent changes in the transportation field may have a profound effect on traffic
assignment techniques. The first is the increasing importance of environmental objectives …

In this report, we compare the computational efficiency and results of solving two alternative
models for the problem of determining improvements to an urban road network. Using a …

Optimization models and methods for an equilibrium traffic assignment is a very specific
research field. It is well known that a traffic assignment problem can be formulated in the …

This study reviews, in two parts, the formulation, interpretation, and solution methodology of
the traffic assignment problem with elastic demands, originally described by Beckmann …

This paper presents an overview of the elements of traffic assignment and a synthesis of the
problems that may be encountered in applying traffic-assignment models in practice. The …

This paper presents a nonlinear programming formulation of the dynamic user-equilibrium
assignment problem (DUE) for urban road networks with multiple trip origins and …

A network optimization problem is formulated which yields a probabilistic equilibrated traffic
assignment incorporating congestion effects and which as a special case, reduces to a user …

This paper presents a methodology of assigning traffic in a network with the consideration of
air quality. Traffic assignment is formulated as an optimization problem considering travel …

Traffic assignment models can be classified according to the behavioral assumption
governing route choice. The deterministic user equilibrium (UE), stochastic user equilibrium …
