註釋The purpose of this study is to develop on-road emission factor estimates for carbon monoxide (CO) and hydrocarbon (HC) emissions from school and transit buses. Infrared remote sensing was employed to collect exhaust emissions data. Data were collected at 10 locations selected based upon logistical needs for deployment of the remote sensing device and expectations regarding traffic volumes for the selected bus fleets. A total of 1,340 valid remote sensing measurements of on-road emissions ratios of CO/CO2 and HC/CO2 were obtained for 265 diesel-fueled school buses, 36 gasoline-fueled school buses, 19 diesel-fueled transit buses of the Triangle Transit Authority (TTA), 3 gasoline-fueled buses of TTA, and 12 diesel-fueled transit buses at Raleigh Durham International Airport (RDU) over the course of 22 days of field work. Limitations of remote sensing and of the estimated emission factors are discussed, and recommendations are made regarding priorities for future data collection and analysis.
