This study explores why people aren't cycling more, focusing on safety, traffic, and infrastructure. Research includes GPS data and survey results to evaluate the impact on route choice and cycling behavior, particularly for women. The findings shed light on the importance of bike infrastructure in promoting cycling as a mode of transportation.

Where do people bicycle?The roles of safety, traffic and infrastructure Jennifer Dill, Ph.D. Center for Transportation Studies
Research Project • Where the data are from • Random phone survey of over 500 Portland area adults (Fall 2005) • GPS data collected from 164 bicyclists for one week each (April through November 2007) • Where the money came from • Active Living Research program of the Robert Wood Johnson Foundation • Oregon Transportation Research & Education Consortium (OTREC)
Traffic is a particular concern for women • Women are less likely to cycle for transportation
Traffic and safety concerns are holding back infrequent cyclists
Priorities for route choice Data from trips recorded by GPS. Excluded transit and exercise trips
The role of infrastructure • 1,777 bike trips that were 100% on bike • of 1,952 total • Compared trips to “shortest path” routes
Actual Trips Shortest Paths
Cyclists are using bike infrastructure Excludes trips involving transit, trips with the main purpose of exercise, organized rides, and trips starting and ending at the same place
Cyclists are using bike infrastructure Excludes trips involving transit, trips with the main purpose of exercise, organized rides, and trips starting and ending at the same place
Cyclists are going longer distances to use bicycle infrastructure Excludes trips involving transit, trips with the main purpose of exercise, organized rides, and trips starting and ending at the same place
Comparing Men and Women Excludes trips involving transit, trips with the main purpose of exercise, organized rides, and trips starting and ending at the same place
Comparing Men and Women Excludes trips involving transit, trips with the main purpose of exercise, organized rides, and trips starting and ending at the same place
