Heavy-Duty Vehicle Fleet Characterization of Reduction of NOx and Particulate Matter Emissions in the South Coast Air Basin

摘要

This report presents findings in a research project that studies heavy-duty vehicle (HDV) fleets and heavy-duty truck (HDT) operations in the South Coast Air Basin (SoCAB, the Basin). Because HDVs are considered to be major contributions to NO-x and PM emissions in the SoCAB, HDV, HDT characteristics and their emissions need to be examined carefully in order to control their emissions more effectively.
