Mode Share and Safety Rankings
(2012, January) The Benchmarking Report by the Alliance for Biking and Walking ranks San Francisco as the 4th highest city in the country for biking commute share and 6th for bike safety. The latest report (2012) and reports from previous years are available at the Alliance for Bicycling and Walking Benchmarking Report webpage.
Reports and Studies
The SFMTA performs studies of San Francisco's bicycling environment and SFMTA facilities on an ongoing basis. Please read below for descriptions and links for a variety of reports.
(Multiple Years) The SFMTA's Citywide Bicycle Count Reports provide a detailed description of Livable Street’s summer citywide bicycle counts. This annual count is conducted at key intersections and corridors throughout the San Francisco, with a special focus on locations most frequently used by bicyclists (Market Street and Mission Corridors, for example). In addition to cyclist count data, the report contains information on observed helmet use and proper use of city bicycle facilities. A steady increase in bicycle usage has been observed each year since the counts began in 2006. Reports are available for the following years:
Other Bicycle Reports
(2012, May) In 2011 SFMTA teamed with Corey, Canapary & Galanis to conduct two surveys of San Francisco residents to gauge their feelings about cycling and to gauge their propensity for taking bike trips in the city. The first survey can best be described as an attitudinal bicycling study about cycling infrastructure, safety and feelings about bicycling. The second survey focused on what transportation planners call “mode split” or “mode share.” The goal here was to have randomly surveyed San Francisco residents fill out trip diaries to understand how many trips are taken by bicycle versus other modes like driving, taxis or transit. In 2011, that number was about 3.5% of all trips in the city are taken by bicycle. The San Francisco Board of Supervisors and SFMTA have set goals to grow that mode share dramatically in the coming years.
(2010, November) The Effect of Green Bike Lanes on Fell Street near Arco gas station and Divisadero Street (pdf) provides a summary analysis of the effects on motorist behavior before and after the green color was added to the bike lane on Fell Street between Scott and Divisadero Streets.
(2009, September) The Licensing of Bicycles and Cyclists in San Francisco Memo (pdf) from SFMTA staff to the SFMTA Board of Directors outlines legal authority, opportunities and challenges of licensing bicycles and of licensing bicyclists.
(2009, June) The San Francisco Bicycle Plan and related documents are available from the San Francisco Bicycle Plan webpage.
(2009, May) The SFMTA periodically releases a State of Cycling report intended to give a snapshot of cycling in San Francisco. The report provides a baseline analysis of bicycling from information gathered via bicycle counts and surveys in years preceding each release. 2008 San Francisco State of Cycling Report (pdf)
(2009) The Collision Report Page links to the latest collision data, trends and analysis for a specific year. Past collision reports providing analysis of bicycle injury collisions in San Francisco include:
(2005, October) The Fell and Masonic Intersection Survey (pdf) assesses the impact of recent intersection changes to pathway users. The intersection of Fell Street with Masonic Avenue includes the Panhandle Path, which carries a significant volume of bicyclists and pedestrians in the east-west direction. In response to concerns related to conflicts between path-users and westbound motor vehicle traffic turning left from Fell Street onto Masonic Avenue, several changes to the intersection were made in March 2005.
(2004, November) The report "Floating Bike Lanes" or Bicycle Accommodation along Part-time Parking (pdf) describes the process and eventual design of accommodating bicyclists along an arterial with a part-time parking/travel lane. The design along the Embarcadero in San Francisco sets aside road space for cyclists which shifts according to the time of day and whether parking is allowed or not.
(2004, August) Steps to Bicycle Facility Implementation (pdf) details the planning process for bicycle facility implementation, taking many considerations into account. It also details the legislative procedures necessary forbicycle facility implementation in San Francisco.
(2004, July) The Garage Bicycle Parking Compliance Report (pdf) lists detailed information regarding the compliance status of public garages, including City-owned garages, and private garages with the City Ordinance 155.2, which requires adequate amounts of bicycle parking be provided in these facilities.
(2004, March) Fell Street Bicycle Lane (Scott to Baker) and Tow Away Zone Proposal (pdf) is a follow-up to the six month trial of the Fell Street Bicycle Lane.
In January 2005, the Board of Supervisors unanimously voted to retain the bike lane on Fell Street from Scott to Baker Streets and to rescind the evening tow-away along Fell Street from Laguna to Baker Streets. The report also presents DPT's proposal to revoke the existing weekday evening tow-away along Fell Street from Laguna to Baker Streets.
(2003, September) Supplemental Design Guidelines (pdf) details supplemental design treatments for current or potential bicycle facilities within the City and County of San Francisco. Prepared by Alta Planning + Design for the San Francisco Department of Parking and Traffics Bicycle Program.
(2003, July) Bikes Allowed Use of Full Lane, Change Lanes to Pass Signage Summary (pdf) describes the placement of signage to encourage "road sharing".
(2002, December) Fell Street Trial Tow-Away Closure, Scott to Baker Streets (pdf) describes the results of a 3-day trial closure of the south side tow-away lane on Fell Street between Scott and Baker Streets. The proposal is to close the tow-away lane and convert to full time parking plus full time bike lane for a 6-month trial.
(2001, June) Seventh Street Bike Lane Traffic Impact Study (pdf) details a proposal by the Department of Parking and Traffic to include a Class II bikeway (bike lanes) on 7th Street between Townsend and 16th Streets as part of the Mission Bay Development. The report discusses the feasibility of bike lanes on 7th Street using traffic volume projections based on build out of Mission Bay in 2015, and outlines the procedure to change the original plans for 7th Street, which included an additional traffic lane in lieu of a bike lane. This report includes Sychro traffic modeling and a flow chart on how to change Infrastructure Agreement Plans. Bike lanes on 7th Street were accepted as a change and were striped in 2003.
(2001, May) Polk Street Lane Removal/ Bike Lane Trial Evaluation (pdf) presents a before and after study of a lane removal/ bike lane project on Polk Street. Data on how bicycle, transit, and motor vehicle traffic was affected by the 6 month trial lane removal/bike lane installation are presented and discussed. The Board of Supervisors voted to retain the project.
(2000, December) Valencia Street Bike Lanes, A One Year Evaluation (pdf) is the byproduct of a one-year trial implementation of bicycle lanes on Valencia Street. As these bike lanes required a controversial "road diet" lane removal, one of the first in San Francisco and along a commercial arterial, the project was implemented on a trial basis. This document reports the effect of the project on bicycle, transit, and motor vehicle traffic in the corridor, and sets the stage for future road diet projects in the City. The Board of Supervisors voted to retain the bike lanes in 2001.
(1998) Implementing San Francisco's Bicycle Route and Sign System (pdf) describes the design and implementation of the City's bicycle route network and innovative sign system. San Francisco Bike Route Signs have influenced the designs of the California state sign SG-45 and the national sign M1-8 . In addition to the text discussion, drawings and specifications of San Francisco's bicycle route network sign are included.
(1993, August) Bicycle Rack Placement Criteria (pdf) outlines the basic criteria of placing a bicycle rack within the Public Right-of-Way of San Francisco. This criteria was approved by the Interdepartmental Staff Committee on Traffic and Transportation (ISCOTT) in 1993. Since that time, the DPT primarily focuses on the installation of inverted "U" or "staple" bicycle racks.
