Guidance for Separated/Buffered Bike Lanes With Delineators

  • Four photographs show different bike land designs along roadways: a lane with (clockwise, from left) a low metal bar barrier, intermittent flexible posts, a raised curb and a lane that is completely separate from the roadway.
  • Paired photographs show bike lanes in winter along a roadway from the point of view of the gloved cyclist, looking forward over the handlebars. The upper image shows a bike lane with some snow and no other riders. The lower image shows a lane with a bare pavement path and another cyclist ahead.

Summary:

Cities across the country are installing separated bike lanes (SBLs) to encourage bicycling as a means of transportation, but current SBL design guidance is incomplete. Researchers collected all existing SBL guidance to determine the gaps in knowledge. They interviewed planners and designers to learn about their challenges. Then they surveyed hundreds of Minnesota bicyclists about their bike lane preferences, including aspects of winter riding. SBL design guidance is evolving. This project gathered an enormous amount of data, practitioner perspectives and user information to fill in the gaps of SBL design knowledge. It is a step toward making safe urban bike networks more common.
