Abstract

This report provides a review and assessment of several important aspects of U.S. Environmental Protection Agency’s MOBILE emissions factor model, which is used for estimating emissions factors
for mobile source inventories. Inventory models like MOBILE have many uses, but the focus of this research is on possible improvements for input data used in quantifying emissions related to certain inspection and maintenance programs. The report assesses the MOBILE model’s strengths and weaknesses toward accounting for driver behavior in relation to inspection and maintenance programs, and how future improvements to the MOBILE emissions factor model may assist toward improving future estimates of program effectiveness for policy and decisionmaking purposes.

Abstract

The Center for Transportation and the Environment (CTE) performed a literature review for FHWA on fuel consumption models as a factor of speed or acceleration. Nearly 50 research papers, conference proceedings, and articles are summarized for the years 1985 - 1996. The CTE used five databases for purposes of searching relevant topics covered under this subject.
