# Bus lanes

## Introduction

**Bus Lane Feature Type definition**: A linear feature that describes a bus lane and its relationship to the road network.

A bus lane is defined as a section of road that is segregated by a physical feature or painted section of road that indicates primary usage for buses; this can include Guided Busways and Bus Gates.

Please note, the [Bus Lane Feature Type](/osngd/data-structure/transport/transport-network/bus-lane.md) represents designated bus lane infrastructure and not bus routes.

## Use cases and applications

Bus lane data support a variety of use cases and applications:

* Planning and managing the impact of street works
* Asset management of bus lane infrastructure
* Supporting transport planning and improving bus services to help citizens access public services
* Supporting understanding of where bus lanes can extend the provision of cycling routes for active travel

## Data provision

Bus lane data are provided in two ways:

* The [Bus Lane Feature Type](/osngd/data-structure/transport/transport-network/bus-lane.md) in the OS Transport Network Collection
* Attribution on the [Road Link Feature Type](/osngd/data-structure/transport/transport-network/road-link.md) in the OS Transport Network Collection

## What you'll find in this sub-section
