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 …

Accurately estimating mobile source emissions is critical because it determines unbiased
transportation conformity and evaluations of emission control measures. However, the traffic …

The current method used for calculating vehicle emissions integrates travel data and
associated vehicle emission factors. Travel data from traditional travel demand models are …

When translating travel demand model output to photochemical model input, period-based
network assignment volumes must be converted to gridded-hourly vehicle emissions. A post …

Until recently, the transportation community lacked the tools needed to conduct project-level
emissions analysis. The recent development of emissions models such as the MOtor Vehicle …

In the United States, most emissions modeling is done using the MOBILE suite of programs.
One of the inputs required is vehicle kilometers of travel (VKT) for each vehicle class as a …

The use of complex emissions models such as Environmental Protection Agency (EPA)
MOVES to estimate air pollution impacts transportation models is constrained by significant …

The network component of an integrated urban model called IMULATE is interfaced with the
MOBILE5. C emissions models. IMULATE produces estimates of traffic flows and average …

New emissions models for predicting carbon monoxide, hydrocarbons, and oxides of
nitrogen require as input not only average speed but various measures of dynamic vehicular …

Accurate road-traffic emission inventories are of great interest to metropolitan planning
agencies especially in the appraisal of regional transport policies. Integrated road transport …
