Autonomous ADL Enviro200 buses begin on-route testing in Scotland

Live testing of ADL autonomous buses is underway in Scotland ahead of passenger services starting later this year. Stagecoach will be conducting a two-week on-road trial of the autonomous bus with Fusion Processing, ADL and Transport Scotland. No passengers are carried in the tests, which are in preparation for the launch of the CAVForth pilot service later this year. 

The Project CAVForth pilot, which is jointly funded by the UK Government’s Centre for Connected and Autonomous Vehicles and the project partners Fusion, ADL, Stagecoach and Transport Scotland, will see five autonomous ADL Enviro200 single-deck buses operating at SAE Level 4 over the Forth Road Bridge between Ferrytoll Park and Ride in Fife and the Edinburgh Park train and tram interchange. 

The buses are fitted with Fusion Processing’s sensor and control technology, CAVStar, that enables them to run on pre-selected roads without the safety driver having to intervene or take control. The buses will provide a service capable of carrying up to 36 passengers at a time over the 14 miles across the bridge, with capacity for over 10,000 passengers a week.

The on-road testing in Scotland follows successful depot-based trials, track testing and virtual simulation where the buses have been put through their paces to fine tune the autonomous drive systems.

More than 20 specially trained ‘Autonomous Bus Professionals’ will soon be recruited by Stagecoach from its East Scotland business. When the service goes live, these drivers will monitor the autonomous system alongside a bus ‘Captain’ who will move around the saloon, talking to passengers about the service and answering any questions they may have, demonstrating what a future service might feel like when the staff member is able to leave the cab while the computer does the driving.

Chris Gall, ADL group engineering director, says: “Today’s start of on-route testing is a milestone for our autonomous bus project. In partnership with Stagecoach, Fusion Processing and Transport Scotland, Project CAVForth helps us to explore new technologies that will make buses even safer and even more efficient. 

“As we move towards passenger services later in the year, the project will be a landmark demonstration of future technologies in transport.”

Sam Greer, regional director for Stagecoach in Scotland, adds: “This is a hugely exciting project for Scotland and we are pleased to be starting live testing on roads today. This is a major step forward in our journey to fully launch the UK’s first full-sized autonomous bus service and will provide easy access to a brand new bus route in the heart of East Scotland.”
