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.
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.
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.
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.
