On-Road Remote Sensing of Automobile Emissions in the Tulsa Area: Year 1, September 2003

The University of Denver conducted a five-day remote sensing study in the Tulsa, Oklahoma area in September of 2003. The remote sensor used in this study measures the ratios of CO, HC, and NO to CO2 in motor vehicle exhaust. From these ratios, we calculate the percent concentrations of CO, CO2, HC and NO in the exhaust that would be observed by a tailpipe probe, corrected for water and any excess oxygen not involved in combustion. Mass emissions per mass or volume of fuel can also be determined. The system used in this study was configured to determine the speed and acceleration of the vehicle, and was accompanied by a video system to record the license plate of the vehicle. Five days of fieldwork, September 8-12, 2003, were conducted on the uphill interchange ramp from westbound US64 (Broken Arrow Expressway) to southbound US169. A database was compiled containing 20,318 records for which the State of Oklahoma, the Cherokee Nation and the Muscogee (Creek) Nation provided registration information. All of these records contained valid measurements for at least CO and CO2, and 20,295 records contained valid measurements for HC and NO as well. The database was compiled by the University of Denver, Department of Chemistry and Biochemistry.
