Stagecoach launched the UK’s first full-size autonomous bus service, AB1, in May 2023. Operating on a 14-mile route, these autonomous buses navigate mixed traffic at up to 50 mph speeds. The fleet consists of four full-size single-deck vehicles, each accommodating 36 passengers.
The development of AB1 incorporated feedback from over 500 members of the public, reflecting a passenger-centric approach. Despite the autonomous capabilities, public preference led to the inclusion of a ‘Captain’ role, where a safety driver monitors the system and ensures compliance with testing regulations. Additionally, a second staff member onboard engages with passengers, reassures first-time users, and manages ticketing, illustrating Stagecoach’s vision of staff roles in the future.
The AB1 service runs seven days a week, departing every 30 minutes from Ferrytoll Park and Ride in Fife. It crosses the Forth Road Bridge, stops at Upper South Queensferry, and continues to Edinburgh Park Transport Interchange, providing a vital connection between Fife and West Edinburgh. Since its inception, AB1 has completed over 9,000 services with a 99.8% reliability rate, covering nearly 80,000 km autonomously.
Stagecoach continues collaborating with government bodies such as the Centre for Connected & Autonomous Vehicles, contributing to developing best practices in autonomous transport. The AB1 project has attracted interest from industry, academia, and civil services stakeholders, with visitors from South Korea, Australia, Europe, and the UK coming to Scotland to learn about and trial this groundbreaking technology.
