Introduction

The Transportation Authority conducted the District 4 Mobility Study to explore ways to increase the use of non-automobile modes in the Outer Sunset and Parkside neighborhoods. The study aimed to improve health, livability, and economic vitality in District 4 while addressing climate change at the local level. 

Past studies showed that one of the main ways residents of District 4 get around is by driving alone. Reducing single occupancy vehicle use would provide a number of benefits for the district, as decreased vehicle miles traveled correlates with increased safety for all road users and results in lower greenhouse gas emissions. More people walking, biking, and taking transit would reduce congestion and support the local economy by making it easier for residents and visitors to access commercial districts. 

This District 4 Mobility Study explored how District 4 residents get around, identifed trips that have high shares of single-occupancy vehicle trips, and explored short and medium-term strategies to reduce these drive-alone trips.

As part of the District 4 Mobility Study, the Transportation Authority also conducted the Great Highway Concepts Evaluation which explored long-term options for the future of the Upper Great Highway from Sloat Blvd to Lincoln Way. 

District 4 Supervisor and Transportation Authority Board Member Gordon Mar asked the Transportation Authority to conduct these studies as part of its Neighborhood Program.

The District 4 Mobility Study is part of Sunset Forward, a collaboration between the Office of District 4 Supervisor and Transportation Authority Board Member Gordon Mar, the San Francisco Planning Department, the San Francisco County Transportation Authority, and the District 4 Youth and Families Network, a coalition of non-profit community based-organizations in the Sunset District.
