LADOT to Begin Adding Sharrows to an Additional 20 Miles of Streets

New Sharrows on Reseda Boulevard

Sharrows on 4th Street

After sharrowing 20 miles of roads in October 2011, LADOT crews will be sharrowing another 20 miles, starting this month. “Sharrows” are shorthand for Shared Lane Markings (SLMs), and are used to identify streets that are designated as shared roadways for bicyclists and motorists.

According to the Department’s Sharrow Report, SLMs have three primary functions: to be a supplemental wayfinding device, to help announce the presence of bicyclists to motorists, and inform bicyclists where they should ride to prevent “dooring“.

Sharrow Installation

With that in mind, LADOT installs sharrows to:

  • Provide gap closures in the Class II (Bike Lane) network (in the near term)
  • Enhance Class III (Bike Route) Bikeways – This includes future BFS facilities
  • Improve bicycling conditions on two-lane roadways with dashed centerlines, specifically

This batch of sharrows tentatively totals 22.64 miles, and a good portion of them were prioritized to support  the upcoming bicycle sharing system.

Streets to be sharrowed can be seen here (More streets can be seen by clicking “Page 2” at the bottom of the left column).

Highlighted SLM Experiment Approved by CTCDC

Update: Minutes from the CTCDC Meeting are now available.

Yesterday the LADOT bikeways team presented a proposal to experiment with green highlighted shared lane markings (HSLM) at the California Traffic Control Devices (CTCDC) board meeting in Santa Ana. According to the 2012 CA MUTCD, Shared lane markings (or sharrows) are intended to:

  • Reduce the chance of bicyclists impacting open doors of parked vehicles on a shared roadway with on-street parallel parking.
  • Alert road users within a narrow traveled way of the lateral location where bicyclists ride.
  • Be used only on roadways without marked bicycle lanes or shoulders.

Our proposed HSLM experiment will be conducted along a stretch of Gayley Ave. (between Weyburn Ave. and Lindbrook Dr.) out in Westwood Village.
