摘要：	Hot-spot analysis, also known as project-level assesses of transportation emissions on local air pollution of carbon monoxide (CO), air-toxics and particulate matter (PM), it is required for regional transportation plans (RTP), transportation improvement programs (TIP) and transportation project development/modification by transportation conformity rules and NEPA process. Such transportation conformity studies are particularly important in non-attainment areas and locales with concentrated and heavily traveled transportation infrastructures (e.g., major transportation corridors, border crossings, congested intersections, etc.). Gaussian plume dispersion models of line sources such as CALINE4 have been widely used in quantitatve hot-spot analysis of CO from transportation sources and have proven successful in modeling inert gaseous pollutants such as CO with sound scientific basis satisfying empirical accuracy. However, the current hotspot analysis modeling tools used by the transportation management community are not capable of simulating the air quality impact of complex roadway network in typical network in typical urban environments and not treating explicitly the various turbulent mixing processes near roadways. Those limitations hinder the accurate assessment of environmental and health impacts of transportation emissions.
