Adelaide’s 12-kilometer [7.4-mile] O-Bahn Guided Busway opened in 1986 and was completed in 1989. The 6.2-meter-wide [20-foot-wide] busway links downtown Adelaide with the northeastern suburbs. Standard and articulated buses circulate in residential areas before entering the three-station busway.
A combination of concrete tracks and buses equipped with special lateral guidewheels allows the vehicles to operate manually, with normal service on roads, and automatically on the guideway by connecting the protruding guidewheels to the concrete track.
Speeds of up to 100 km/h [62 mph] are reached, cutting the journey time by more than half. Ridership has increased steadily since 1986 to about 30,000 per day.
Construction costs were approximated at $100 million in Australian dollars (A).
“Just when you think you’ve seen everything in the transportation world, you encounter something different.”
“At 16 miles, the Cambridge guided busway is the longest one in the world. Bus speeds can reach up to 55 mph.”
