Guided bus

Guided buses are buses capable of being steered by external means, usually on a dedicated track or roll way that excludes other traffic, permitting the maintenance of schedules even during rush hours. Unlike railbus, trolleybuses or rubber-tyred trams, for part of their routes guided buses are able to share road space with general traffic along conventional roads, or with conventional buses on standard bus lanes.

Guidance systems can be physical, such as kerbs or guide bars, or remote, such as optical or radio guidance.

Guided buses may be articulated, allowing more passengers, but not as many as light rail or trams, which are not constrained to a regulated maximum size in order to freely navigate public roads.
