Bicycling as a Solution to Yosemite Valley Traffic

Principal Investigator Susan Handy, Ph.D.
University of California, Davis

Yosemite National Park attracts 4.5 million visitors a year, 60% of whom spend at least some time in Yosemite Valley where many of the park’s natural wonders are found. Bicycles have been a popular travel alternative within the valley. The purpose of this project is to explore the potential for bicycling to play a larger role in the effort to manage Yosemite Valley traffic and reduce environmental impacts.
