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

In most of the larger urbanized areas, a travel forecasting model is used to estimate
tripmaking activity for future years. Various other impacts can be derived from these traffic …

The failures of models used in the analysis of travel and vehicle emissions effects of
transportation plans and policies have been enumerated by many in the transportation …

Emission reduction strategies are gaining greater attention as a support of the national
objective for a sustainable and green transportation system. A large percentage of the …

An initial attempt is made to quantify vehicle emissions in the Greater Toronto Area (GTA) in
Canada by exploiting travel information provided by activity-based 24-h models rather than …

Emission reduction strategies are gaining attention as planning agencies work towards
adherence to air quality conformity standards. As state departments of transportation (DOTs) …

Vehicle emission models enable transportation planners to evaluate the environmental
implications of alternative transportation policies and assist decision makers in selecting the …

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 …

Transportation conformity is a US regulatory process that requires that transportation
modeling be integrated with air quality modeling. Consequently, every change to either …

This paper demonstrates, tests and shows the value of activity-based travel demand models
and household sample enumeration forecasting techniques in evaluating the transportation …
