MOBILE
Abstract
The MOBILE series of models were EPA’s approved models for estimating pollution from highway vehicles for many years. MOBILE6.2, released in 2004, was the last version in that series. The MOBILE series has been superseded by the Motor Vehicle Emission Simulator (MOVES). MOBILE calculates emissions of hydrocarbons (HC), oxides of nitrogen (NOx), and carbon monoxide (CO) from passenger cars, motorcycles, and light- and heavy-duty trucks. MOBILE is based on emissions testing of tens of thousands of vehicles. The model accounts for the emission impacts of factors such as changes in vehicle emission standards, changes in vehicle populations and activity, and variation in local conditions such as temperature, humidity, and fuel quality.
