Portland's Blue Bike Lanes

City of Portland Office of Transportation

To determine whether such colored markings help improve safety at
bicycle-motor vehicle crossings, the City of Portland has been experimenting
with blue pavement markings to delineate selected conflict areas.
The University of North Carolina Highway Safety Research Center
(UNCHSRC) -- under contract to the Federal Highway Administration --
analyzed the project data.
