Final report to the California Air Resources Board under Contract No. A932-189.

The University of Denver remote sensor for on-road motor vehicle carbon monoxide emissions was used for eleven days in the Los Angeles Basin in December, 1989. The remote sensor has been incorporated into the 1990 Clean Air Act Amendments as "on-road emissions testing". The device measures the CO/CO2 ratio for one-half second behind each vehicle, from which the exhaust %CO is calculated. Vehicles were measured in a mix of many driving modes and speeds ranging from deceleration coming up to a red traffic light through idling in …

EPA Pub 600/4-90/032 (NTIS PB91148320)

Carbon monoxide (CO) emission measurements of thousands of vehicles per day are possible with a recently evaluated remote sensor developed at the University of Denver. Funded by the Environmental Monitoring Systems Laboratory - Las Vegas (EMSL- LV) Innovative Research Program, the evaluation has demonstrated the comparability of volume concentration measurements made by this method with traditional emission monitoring instrumentation. Measurements are made unobtrusively as vehicles pass through an infrared light beam directed across one traffic lane about 25 centimeters above the pavement. A video camera records the vehicle registration number of each vehicle as its …
