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

Crowdsourcing the Collection of Transportation Behavior Data

Christopher Bone Marc Schlossberg , Ken Kato , James Meacham
Understanding the travel behaviors of individuals who use public transit is essential for enhancing the performance, sustainability and efficiency of public transportation. Contemporary methods for collecting data on transportation behavior are focused on manual or automated procedures for counting the number of individual passengers entering or exiting transit vehicles. While such methods provide useful data for understanding transit demand throughout a network, they ignore the important… Read More
