Campaigns > Traffic Calming

Reducing the speeds of motor traffic on residential streets using traffic calming techniques reduces injuries to bicyclists and pedestrians by 50-75%. In Seattle and Portland, traffic calming is common, but in San Francisco there is no traffic calming plan. The SFBC aims to educate the public about the benefits of traffic calming and coordinate efforts among residents to improve their streets through such measures as the installation of speed humps, traffic circles, traffic diverters and barriers, curb extensions, and raised intersections.

In 1999, the SFBC celebrated a major victory when the Mayor announced a $2.3 million dollar traffic calming program called "Livable Streets." His 2001-2002 budget renewed the program.
