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

An Update of E-Bike Purchase Incentive Programs in North America

John MacArthur
The electric bicycle (e-bike) is a low-emission mode of transportation that offers communities benefits in the areas of health, planning, time, cost, street safety, congestion, air pollution, noise pollution, and energy security (Benoît et al., 2011). E-bikes enable more people to ride a bicycle for longer distances despite physical limitations, difficult terrain, and the presence of cargo (MacArthur et al., 2018). In the most recent U.S. National Household Travel Survey (NHTS), completed in… Read More
