Guided bus

Guided buses are buses 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.

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 that do not also freely navigate public roads.

History

Only a few examples currently exist, but more are proposed in various countries.

The first guided busway in the United Kingdom was in Birmingham, branded as Tracline 65, 1,968 feet (600 m) long, experimentally in 1984. It has since been removed. A number of guided busways have since been planned or built in the United Kingdom. In Mannheim, Germany, from May 1992 to September 2005 a guided busway shared the tram alignment for a few hundred metres, which allowed buses to avoid a congested stretch of road where there was no space for an extra traffic lane. It was discontinued as the majority of buses fitted with guide wheels were withdrawn for age reasons. There are no plans to convert newer buses.
