Development of a Model to Predict and Mitigate Environmental and Public Health Impacts of Traffic Flows and Traffic Management Policies in Urban Transportation Microenvironments

Linda George
Christopher Monsere , Miguel Figliozzi
Urban residents spend a considerable amount of time in transportation microenvironments as pedestrians, bicyclists, public transit users, residents and workers situated along roadways, and automobile commuters. Within these microenvironments, vehicles powered by carbon-based fuels (e.g., gasoline, diesel) have a negative impact on air quality. Vehicular exhaust is the source of a multitude of air contaminants, including particulate matter (PM). Particulate matter of concern ranges in size fro... Read More
