Boulder tests green bike lanes at high-collision locations
Cyclists and motorists traveling north along Folsom Street will notice something new at the intersections of Canyon Boulevard and Pearl Street – green bike lanes. As part of a pilot project, the City of Boulder’s Transportation Division has installed the new pavement markings to promote community awareness and increase safety for both cyclists and motorists.
The city is testing the green bike lanes’ effectiveness with reducing “right hook” collisions, which involve a motorist making a right turn and accidentally colliding with a cyclist traveling in the same direction in the adjacent bike lane, as depicted in the following diagram.
Citywide, approximately 14 percent of all motor vehicle collisions involving cyclists have been attributed to right hook collisions. The intersections of Folsom Street and Canyon Boulevard (#2) and Folsom and Pearl streets (#12) were identified among the top 15 most common collision locations. These statistics were included in the Safe Streets Boulder Report, a study of motor vehicle collisions involving cyclists or pedestrians during a 40-month period between January 2008 and April 2011.
The new pavement markings on Folsom Street are the first phase of the pilot project, with additional green bike lanes planned along Colorado Avenue and Table Mesa Drive this fall. Evaluations to test the effectiveness of the markings will include field observations and an online community survey to gather input from cyclists and motorists.
The green bike lanes are a traffic engineering component of the city’s three-part action plan to reduce the number of traffic collisions in Boulder through engineering, education and enforcement. The Heads Up Boulder: Mind the Crosswalk campaign was launched this summer to help educate the community about three new crosswalk safety ordinances and the Boulder Police Department will be proactively enforcing the ordinances at Boulder’s busiest intersections this fall.
The new pavement markings were installed on Thursday, Sept. 6, using a preformed thermoplastic material that includes an anti-skid layer to reduce slipping.
Boulder is joining other communities such as Portland, Ore.; Seattle, Wash.; St. Petersburg, Fla.; Los Angeles, Calif.; and San Francisco, Calif. in experimenting with bike lane pavement markings.
