A multiple user class equilibrium assignment algorithm is formulated to determine vehicle
trips and the vehicle miles of travel (VMT) in various operating modes on highway links. A …

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 …

Dynamic traffic assignment and observed traffic counts are used to estimate the distribution
of departure times in an urban area trip matrix. The objective is to find the maximum entropy …

Road traffic assignment, or forecasting route and link flows corresponding to fixed matrices
of origin-destination (OD) flows by vehicle class on a road network for a given time period, is …

This paper reports on the evaluation of alternative algorithms for dynamic, or time-varying,
equilibrium traffic assignment. The algorithms are used for pre-trip assignment, which …

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 …

Safwat and Magnanti (1988) have developed a combined trip generation, trip distribution,
modal split, and traffic assignment model that can predict demand and performance levels …

Maintaining air‐quality standards is a major concern for transportation planners and policy
makers in the United States. This necessitates considering nontraditional emission …

An emission inventory is a key component of an air quality control program. The emission
rates of carbon monoxide and hydrocarbons are sensitive to the variations in the inputs …

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