SFMTA’s Roundabout Solutions

Last month we requested an update on the new traffic circle at McAllister and Steiner installed earlier this year by the SFMTA as part of their Transit Effectiveness Project/5-Fulton Rapid program. We heard from residents, neighbors and visitors regarding safety and noise concerns relating to the traffic circle, also called a roundabout.

Instead of a traditional four-way stop, first-come first served model, the roundabout at McAllister/Steiner requires a stop only for North-South traffic on Steiner, creating confusion on who has the right of way.

SFMTA responds

An SFMTA evaluation of the traffic circle is underway. The evaluation will measure the following factors:

  • Whether drivers are using the traffic circle properly
  • Driver compliance with the STOP signs
  • Drivers yielding to pedestrians
  • Any encroachment on the circle or sidewalks
  • Whether drivers are making left turns properly
  • Traffic volumes and speeds on McAllister and Steiner
  • Transit travel time savings
  • Transit operator honking
  • Any other issues observed during site visits

This will determine whether the design meets the shared goals of safety, Muni reliability, and traffic flow.

Near-Term Changes

Better Signage:

Installation of explanatory signage in the circle to make it clear to drivers approaching from ALL directions to proceed through the circle slowly. This will reinforce the message that drivers on the Steiner Street approach need to stop. These signs will complement the “Yield to Pedestrians” signs installed on the McAllister Street approaches on Monday June 4th.

Less Honking:

SFMTA will send Muni inspectors to the intersection tomorrow to ensure 5 Fulton bus drivers do not honk as they approach the Steiner/McAllister intersection. Muni managers will also communicate to operators instructions not to honk.
