Protected bike lanes

Description: To reduce the number of bike crashes and increase bicycle ridership, San Francisco, CA has created protected curbside bike lanes on several busy and otherwise hazardous streets. The projects include protected bikeways featuring concrete islands, green paint, and flexible posts. Similar projects have been completed throughout the U.S., including New York, Washington D.C., Seattle, Oakland, Philadelphia, and many other cities.

Goal: Protected bike lanes to encourage active transport and reduce vehicle miles traveled (VMT)

Measurement: Reduced VMT, increased active transport, reduced bicycle-involved accidents

Time to Implement: Approximately two years from planning to implementation
