Rapid Transit Planning

A key component of the 2016 Master Plan was a network of rapid transit corridors connecting across the four-county RTA region. These high-capacity transit projects are intended to be the backbone of the region’s existing and future public transit services.

Most of the rapid transit network would consist of Bus Rapid Transit, or BRT. Learn more about BRT.
