In this paper, an integrated dynamic framework is applied to model human exposure to
vehicular emissions. The framework contains three components: a time-dependent …

This research aims at developing modeling and scenario-comparison tools to explore the
impacts of various transportation and land use planning policies on changing travel …

The adverse impacts of greenhouse gasses (GHG) and the imperative for reducing the
existing rate of GHG production are well established. In the United States, the largest source …

This paper presents a simulation model developed by PTV AG and the Group Research
Department of the Volkswagen AG. Four separate models are integrated in one software …

Regional vehicle emissions are based on traffic activity data typically obtained from a
conventional four-step travel demand model, with the usual limitation of link volumes …

Travel models are commonly used to forecast vehicle-kilometers traveled (vehicle-miles
traveled) and speed, from which mobile source emissions are calculated. Most existing …

The development of a trip-assignment model designed to systematically compute emissions-
optimized traffic flows for carbon monoxide is explored. Then the exploratory theoretical …
