Advisory Bicycle Lanes Evaluation
In October 2019, the FHWA granted DDOT permission for a trial of the advisory bicycle (bike) lane pattern on five corridors in the Capitol Hill area of the District of Columbia. The concept for advisory bike lanes is that the vehicular lane is a single, 11’ – 18’ wide lane for two way traffic, with no centerline, while the bike lane is 5' wide and continually dashed on the outer edge to indicate that vehicles may cross over this line when necessary to give sufficient clearance to oncoming vehicles. This configuration will allow for bike lanes to be placed on more streets without affecting parking. An ancillary benefit is the anticipated reduction in vehicular speeds on neighborhood roads due to the narrower overall travel lane and absence of a centerline. The evaluation process will be guided by Section 1A.10 of the 2009 MUTCD. “Before” and “after” studies will be performed to assess the performance of the experimental device. Bike lanes or shared lane markings do not exist on either of the facilities identified to receive the experimental treatment. As such, the evaluation process will be primarily focused on their performance after implementation. Bicyclists and motorist behavior will be observed by staff and volunteers along the subject streets after the application of the experimental devices.
