Characterization of the urban roadway atmospheric environment to evaluate transportation impacts and improve exposure assessment

Christine Kendrick
Urban arterials are landscapes that give rise to short and long-term exposures to increased transportation-related pollution. With high traffic volumes and a wide mix of road users such as those waiting for transit, pedestrians, and bicyclists, urban arterial environments are important targets for improved exposure assessment to traffic-related pollution and application of mitigation strategies. This dissertation project uses long-term roadside air quality and traffic monitoring from a… Read More
