VISION ZERO RAMPS | STUDY 2

Pedestrians and autos in SoMa crosswalk IMPROVING STREET SAFETY IN THE GREATER SOMA NEIGHBORHOOD

The Transportation Authority has received Caltrans grant funding to evaluate 10 additional ramp intersections within the greater SoMa neighborhood, building from the smaller first study focused on the Youth and Family Zone. The Transportation Authority and SFMTA are currently studying intersections in this area. 

STUDY RAMP INTERSECTION SELECTION

The Transportation Authority selected the following 10 intersections from all freeway ramp intersections in SoMa based on three key factors:

  • Emphasis on safety: We prioritized intersections with high collision rates.
  • Coordination with other agencies: We focused on intersections that aren’t already being addressed by other City plans and projects.
  • Proactive approach: Some intersections did not have reported collisions, but were selected because they have opportunities for proactive safety improvements (eg. new or upgraded crosswalks).

Over the past 5 years, these intersections have had 111 collisions, of which 9 had severe injuries. In addition, all 10 intersections are in San Francisco's Vision Zero high-injury network, locations in the city that have disproportionate numbers of traffic injuries and fatalities.

Intersection improvements

Examples of improvements may include bulb-outs, signal improvements, crosswalk upgrades, striping improvements, ramp reconfigurations, changes to the number of lanes on a street to calm traffic, or other ideas that emerge through the study process. We intend to develop a mix of near-term improvements that could be on the ground in the next few years and few bigger ideas that might take longer to plan and implement.

 

Study process and community outreach 

The project team will conduct outreach to SoMa residents, employees, and travelers to seek input on the study’s process and goals as well as to gather input on the study intersections. Sign up below to receive updates.
