Managed Lane is an operational practice utilized to address congestion by controlling traffic movement on the highway. Two common approaches to lane management are restricted use based on vehicle eligibility, and control of access through limited ingress/egress. Vehicle eligibility can be based on occupancy or vehicle type.
The concept of Managed Lane was first put into practice in California, in 1962, when an exclusive bus-only lane was established as a temporary traffic management strategy during the reconstruction of the San Francisco-Oakland Bay Bridge. In 1969, the first permanent Managed Lane facility in the United States was opened as a bus-only lane on the Shirley Highway (I-395) in Washington, D.C./Northern Virginia. California’s first permanent Managed Lane facility began in April of 1970 with the High Occupancy Vehicle (HOV) bypass lane at the San Francisco-Oakland Bay Bridge toll plaza.
California’s Managed Lanes comprise of HOV Lanes, Express Lanes and Park and Ride facilities. Information for each program is available at the links below.
