Abstract:

Many cities are considering transportation management measures and/or tailpipe emission controls to reduce the pollution associated with traffic congestion. A major difficulty is the expensive and time consuming task needed to quantify the effect that a traffic reduction measure (or package of measures) would have on Carbon Monoxide (CO) levels at specific locations (hot spots) within an urban area. This generally requires the detailed assessment of many scenarios for a large number of intersections. Provided in this paper is a description of a cost-effective microcomputer based integrated traffic simulation and air quality dispersion modeling process, which has been successfully applied to estimate the effects of large scale projects on carbon monoxide levels in several major urban areas.
