The University of Denver conducted a five-day remote sensing study in the Chicago area in the fall of 1997. The remote sensor used in this study is capable of measuring the ratios of CO, HC, and NO to CO{sub 2} in motor vehicle exhaust. From these ratios, the authors calculate the percent concentrations of CO, CO{sub 2}, HC, and NO in motor vehicle exhaust which would be observed by a tailpipe probe, corrected for water and any excess oxygen not involved in combustion. The system used in this study was also 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 were conducted at the on-ramp from Algonquin Rd. southbound I-290 in west Chicago. A database was compiled containing 18,320 records for which the State of Illinois provided make and model year information. All of these records contained valid measurements for at least CO and CO{sub 2}, and more than 17,500 contained measurements for HC and NO.
