Separated Bike Lanes on Higher Speed Roadways: A Toolkit and Guide

This toolkit includes information references, agency policies, processes, and other resources and procedures that can help agencies overcome the obstacles limiting them from implementing separated bicycle lanes where users most require separation from motor vehicles: on higher speed roads. Despite their importance in higher speed contexts, installations of separated bicycle lanes in the U.S. have so far occurred largely in lower speed environments. This guide synthesizes existing research on separated bicycle lanes, including research on potential benefits and obstacles, as well as on existing design and planning guidance. Using information from the limited case studies available and from stakeholders, this research aims to identify key obstacles, considerations, and experiences of those who have designed, implemented, and maintained separated bike lanes on higher speed roadways.
