Abstract:

California Department of Transportation (Caltrans) is required to use mobile source emission inventory tool known as Emission FACtor (EMFAC) developed by California Air Resources Board (CARB) to estimate and analyze on-road emissions of particulate matter (PM) while other states use the MOVES (Motor Vehicle Emission Simulator) model developed by U.S. Environmental Protection Agency. However, EMFAC brake wear PM emissions factors were developed based on limited data and are outdated. Caltrans funded a research project titled “Brake Wear in Particulate Matter Emission Modeling” to measure brake wear PM emissions and develop updated emission factors in EMFAC for heavy-duty vehicles (HDVs) and advanced regenerative braking technologies used by electric vehicles such as Tesla. The project also developed speed-dependent emission factors that are implemented in EMFAC. CARB funded and completed another research project focusing on light-duty vehicles (LDVs). As such, the HDV research was supplementing the LDV research. Many of the test methods, dynamometer setup, PM measurement and analysis methods are drawn from the LDV work. Eastern Research Group Inc. as a contractor and LINK Engineering Company as a subcontractor conducted the project. The Caltrans HDV project gathered brake PM emissions data on several HDV brake configurations to update EMFAC rates, and a Tesla Model 3 electric vehicle to expand California’s dataset on regenerative braking emissions. The emissions factors developed in this project are fully incorporated on the latest beta version of EMFAC 2021. With the new emissions factors now fully implemented, Caltrans will have the opportunity to have a better and a more realistic estimates of PM emissions when conducting project level air quality conformity analyses.
