Title: Heavy-duty vehicle fleet characterization for reduction of NOx and particulate matter emissions in the South Coast Air Basin.

Principal Investigator / Author(s): Fischer, Michael

Contractor: Jack Faucett Associates

Contract Number: 96-317

Research Program Area: Emissions Monitoring & Control

Topic Areas: Mobile Sources & Fuels


In this report, Jack Faucett Associates (JFA) and its subcontractors present their findings in a research project characterizing the heavy-duty vehicle (HDV) fleets and heavy-duty trucks (HDT) in the South Coast Air Basin (SoCAB, the Basin). Three main objectives this report accomplishes are the following: 1) characterization of the fleet with respect to physical and operational characteristics of the trucks, 2) determination of the emissions associated with relevant subpopulations of trucks and 3) development of an incentive strategy to accelerate and encourage the introduction of low-emission technology and operational practices for the fleets in the SoCAB to achieve NOx and PM emissions reductions.
