Completed L Rapid Safety Improvements

An early implementation of safety measures known as the L Taraval Rapid Project that started in early 2017 is complete! Comprehensive safety features were implemented to enhance safety for people getting on and off Muni and make the L more reliable. These included:

  1. Clear Zones at Train Stops
  2. Painted Safety Zones at Sidewalk Corners
  3. 6-Month Boarding Zone Pilot
  4. Transit Stop Removal
  5. Transit Only Lanes

1) Clear Zones at Train Stops

Clear zones are painted markings on the street that provide a separation between streetcars and the traffic lane. Clear zones make the street safer by giving pedestrians a safe space to step off Muni.

To enhance safety along Taraval Street, clear zones are installed at eight intersections:

  • Taraval Street westbound only (north side):
    • 26th Avenue
    • 30th Avenue
    • 32nd Avenue
    • 40th Avenue
    • 46th Avenue
  • Taraval Street both directions
    • 19th Avenue
    • 42nd Avenue
    • 44th Avenue

The law requires cars to always stop behind trains where passengers get on and off Muni in the street, including at all clear zone locations. Do not pass until the doors are closed.

2) Painted safety zones at sidewalk corners

Safety zones at sidewalk corners help make people walking more visible to drivers when crossing the street. Painted safety zones temporarily extend the sidewalk until permanent, concrete pedestrian bulbs can be installed.

To enhance safety along Taraval Street, painted safety zones will be installed at six intersections, including at 20th, 21st, 22nd, 24th, 33rd and 38th avenues. Concrete pedestrian bulbs will be installed with the larger project starting 2018.

3) Completed 6-month boarding zone pilot

In the five years prior to the start of this project, 22 people were hit getting on and off L Taraval trains where there were no boarding islands. To address this safety issue, a community-driven effort was launched to test whether measures including new street markings, signs and flashing lights on trains would get drivers to stop safely and legally for customers boarding Muni trains on Taraval.

Over a six month period in 2017, a loading zone pilot was evaluated at the inbound stops at 26th, 30th, 32nd, 35th and 40th avenues. If successful, the pilot would preserve parking spaces at these five stops. If the measures failed to increase the share of drivers who stop for loading trains to 90 percent, or if anyone was injured at a pilot location, boarding islands would be installed at each location. Boarding islands are a critical safety improvement feature that provide a safe zone for passengers to get on and off the train.

Since April, data has been collected about how these changes have impacted the share of drivers who stop behind stopped trains. For the final evaluation, each instance where a stopped train interacted with a vehicle was noted and tracked based on whether or not cars stopped behind the train, as required by law.

After months of data collection and many hours of reviewing on-site videos, the results are in. The compliance rate rose slightly, to 74 percent, up from 72 percent prior to changes. Since these measures failed to increase the share of drivers who stop to the 90 percent target rate, boarding islands will be installed at the pilot locations. In total, 36 total parking spaces will be removed as a result.

4) Transit Stop Removal

Nine L Taraval stops were removed to improve travel time and increase reliability.

  • In both directions:
    • Taraval at 28th Avenue
    • Ulloa at 15th Avenue
    • Taraval at 35th Avenue
  • Towards downtown:
    • Taraval at 24th Avenue
  • Towards SF Zoo:
    • Taraval at 17th Avenue
    • Taraval at 22nd Avenue

The inbound stop towards downtown at 15th Avenue and Taraval Street was approved for removal but will remain until a full boarding island can built sometime after 2019.

5) Transit-only lanes

Transit-only lane were painted along the track lane of Taraval Street in both directions. Drivers are able to enter the lanes only to pass or make left turns. The SFMTA is committed to closely evaluating the transit-only lane to measure its impact on congestion and traffic flow for one year to identify any necessary adjustments or mitigations.

    What do I need to know?

    I'm a driver. What do I need to know?

    • It’s the law to stop for streetcar passengers. At every clear zone and pilot location, it’s illegal to pass loading streetcars. Next to concrete boarding islands, you may pass at 10 MPH.
    • The track lane on Taraval Street will now be dedicated to Muni. You can enter the lane when making a permitted left turn, but otherwise drive in the right lane.

    I ride the L. What do I need to know?

    • The new clear zones and upgraded boarding zones are designed to keep you safe while getting on and off Muni. However, do not stand and wait for Muni within the zones or you could risk being hit.
