Guided buses are buses steered for part or all of their route by external means, usually on a dedicated "track" or guideway. This guideway, which often parallels existing roads, excludes all other traffic, permitting the maintenance of reliable schedules on heavily used corridors even during rush hours.
Although guidance systems can be either physical or remote (such as optical or radio guidance), this tag should only apply to physical guidance systems.
Do not use this on normal paved roadways that are designated for buses only.
