Research Highlights

Evaluation of Electric Bike Use at Three Kaiser Permanente NW Employment Centers in Portland Metro Region

John MacArthur
Jennifer Dill
Oregon and Portland in particular, is internationally known for its love for bikes. Not only does the region have some of the highest bike ridership but the Oregon bike manufacturing industry is quickly growing. Oregon’s electric bike (e-bike) market is also growing but little data are available on the potential market and e-bike user behavior and interest. Only a limited amount of research has explored the potential new market segments for e-bikes and the economic, operational, safety, and t... Read More

Bicyclists’ Uptake of Traffic-Related Air Pollution: Effects of the Urban Transportation System

Alex Bigazzi
Urban bicyclists’ intake and uptake of traffic-related air pollution are not well quantified due to a lack of on-road measurements. This uncertainty impedes health-conscious transportation planning, and no quantitative guidance is available on bicycle transportation system management to mitigate uptake. The objective of this research is to provide tools for bicycle transportation planners and managers to explicitly consider air pollution risks in decision-making, and to allow more informed ch...
