Bus only lane

Bus-only lanes provide dedicated space for buses to improve the speed and reliability of transit service.

Introduction

Bus-only lanes provide dedicated space for buses to improve the speed and reliability of transit service. They may be implemented for a select period of time or throughout the entire day depending on context. They can be implemented as part of street reconstruction or street retrofit projects. The Transportation Action Plan includes specific locations for implementation and evaluation for bus-only lanes. Other corridors may be considered on a case-by-case basis. 

Design Considerations

See also transit stops guidance.

Location

Bus-only lanes can be implemented along the curb, in through lanes that are not curbside, or be center running.

Width

Curbside bus-only lanes should typically be 10’ wide in addition to an adjacent 2’ gutter. Non-curbside bus-only lanes should typically be 11’ wide.

Coordination with other transit advantages

Bus-only lanes should typically be implemented in combination with other transit advantages along a corridor, such as transit signal priority and queue jumps.

Color

Bus-only lanes can be painted red to provide additional visibility and clarity for drivers.
