Methodology and Guidelines for Regulating Traffic Flows under Air Quality Constraints in Metropolitan Areas

Project Description

Monitored pollutant concentrations exceed the limits of the National Ambient Air Quality Standards in many metropolitan areas. This project developed a methodology to combine a new pollutant dispersion model with a traffic assignment process to contain air pollution while maximizing mobility. The project produced a model to predict the air quality at receptor sites in metropolitan areas using traffic data and real time meteorological data. Most of the air dispersion models in use do not have a full description of the physical and chemical processes to describe the formation and transformation of pollutants in the metropolitan areas relating to traffic flow. With the air quality model developed in this project, traffic assignments can be conducted taking air quality into account. The air quality can also be considered as an additional objective function while assigning traffic flow in the metropolitan transportation network.
