International Vehicle Emissions (IVE) model

3pm, September 30th, 2015

The International Vehicle Emissions (IVE) model is a computer model designed to estimate emissions from motor vehicles under different technology and driving situations.

The model is intended to help cities and regions:

  • develop emissions estimates to focus control strategies and transportation planning on those that are most effective;
  • predict how different strategies will effect local emissions; and
  • measure progress in reducing emissions over time.

IVE makes estimates of local air pollutants (criteria pollutants), greenhouse gas emissions, and toxic pollutants.

Emissions from vehicles in most countries, particularly developing countries, are not well understood, and the ability to make accurate emissions estimates is critical for air quality management planning. Only a few countries, such as the U.S. and Europe have developed reasonably accurate emissions projection tools, and these models are designed only for their respective regions.

The U.S. and European models cannot take into account the differing technologies and conditions that exist in most developing countries. Most of these existing models do not include the full range of global warming and local toxic emissions that are needed to fully evaluate the impact of motor vehicles. The IVE model is specifically designed to have the flexibility needed by developing nations in their efforts to address mobile source air emissions.

Key questions addressed:

  • What is the quantity of air emissions that come from mobile sources?
  • How will different transportation planning strategies affect local emissions?

Sample data inputs:

  • Vehicle fleet
  • Vehicle activity data
  • Emission rates

Sample quantitative outputs:

  • Criteria, toxic, and global warming gases from on-road mobile sources per hour or per day
