The results of a carbon monoxide and traffic monitoring and analysis program conducted at Oakbrook Shopping Center in the Village of Oak Brook, a Chicago suburb, are reported. The first section of the report describes the details of the carbon monoxide and meteorology monitoring techniques, and it gives a summary of the results. The next section presents a discussion of traffic monitoring locations, and it evaluates the results in terms of the impact of the shopping center on traffic loads at a nearby intersection, trip generation rates, and vehicular operating modes at intersections. The final section integrates the findings described in the other sections by developing a method for approximating emission profiles for queuing vehicles, and testing the composite model formed by the approximated profiles and the HIWAY line source model against carbon monoxide concentrations measured at the study site. A suggested technique for estimating carbon monoxide concentrations near intersections is also presented.
