In November 2008, the SFMTA Board of Directors approved legislation that enabled the SFpark pilot project. It defined the SFpark pilot areas and specified, as required by city law, the ranges and limits for rates and time limits, as well as parking availability targets.
The SFMTA installed new parking meters and parking sensors in pilot areas across the City through the end of 2010. In April 2011, real-time parking data was made publicly available here at SFpark.org, the SFpark smartphone application and as an open-source data feed. In May, the SFMTA began implementing demand-responsive pricing in SFpark pilot areas.
