May 2, 2014 1 Photo credit: Nathan McNeil, PSU Research Objectives • A field-based evaluation of protected bikeways in five U.S. cities to study: – Safety of users (both perceived and actual) – Effectiveness of the design – Perceptions of residents and other road users – Attractiveness to more casual cyclists – Change in economic activity
2 Dearborn Street - Milwaukee Avenue One-way protected lane on both sides on a two- Two-way protected lane on one-way street Chicago, IL - Chicago, IL way street
L Street – Multnomah Street One-way protected lane on both sides on a two- One-way protected lane on a one-way street Washington, DC – Portland, OR way street Rio Grande Street - Oak/Fell Streets – Couplet of one-way protected lanes on one-way Two-way protected lane on one-way street Aus n, TX San Francisco, CA streets
Barton Springs One-way protected lane on the south side of the Bluebonnet Lane – Two-way protected lane on a two-way street Road – Aus n, TX road (other direc on is shared use path) Aus n, TX Data Collected • Resident Surveys – 9,617 surveys mailed – 2,283 returned (34% used online option) – 24% response rate • Bicyclist Surveys – 3,409 bicyclists intercepted – 1,111 surveys completed – 33% response rate • Video Recorded at Intersections – 16 locations in 4 cities – 204 hours analyzed – 21,728 bicyclists and 23,347 turning vehicles observed
