Abstract

Traffic flow is the main pollution source in many urban areas, so when the pollutant concentration is above the permitted level, a common public policy consists of restricting the vehicular traffic. However, this restriction presents a negative impact on the economic activities and the inhabitants mobility. For these reasons different sectors question its efficiency arguing that the pollution reduction is due to wind changes and not to a lower vehicular traffic. In this work we estimate the pollution emission rate and pollutant concentration with a novel methodology that consists of combining the 1D Lighthill-Whitham-Richards (LWR) traffic model for road networks with a 2D advection-diffusion-reaction model for air pollution. This allows us to verify the efficiency of restrictions on vehicular traffic in the framework of numerical simulations in a real urban domain: the Guadalajara Metropolitan Area in Mexico.
