CAVForth: creating Europe's first full-sized autonomous bus
The project has been part-funded by 拢4.5 million from the government鈥檚 Centre for Connected and Autonomous Vehicles (CCAV) and Innovate UK.

Fusion Processing is an SME based in Bristol鈥檚 Future Space. In its 8 years, its automotive products have gained over 1 million miles on the clock and it鈥檚 now leading a consortium developing Europe鈥檚 first full-sized autonomous bus.
A full programme of trials of Fusion鈥檚 CAVstar autonomous drive system installed on Alexander Dennis single-deckers will be taking place during 2020 and 2021. They will feature on a 30-mile route between Fife, across the Forth Road Bridge, to the Edinburgh Park Train and Tram interchange. A successful public demonstration was staged late last year.
CAVForth expects to be carrying passengers by this time next year, running at up to 50mph and more fuel-efficiently than manually driven buses. With services every 20 minutes between 6am and 9pm, there could be 10,000 passenger journeys per week. Five 42-seat buses are being fitted with Fusion Processing鈥檚 CAVstar庐 control and sensing system, integrated with each vehicle鈥檚 steering, throttle and braking systems. CAVstar庐 draws on information from radar, LIDAR, optical cameras and ultrasonic sensors, along with satellite navigation, to detect and avoid objects in all weathers, day and night.
The buses will operate at AV Level 4 autonomy, meaning that the vehicles will operate autonomously along the routes and, whilst there will be regular driver controls, the driver will not be expected to use them, other than in an emergency. As a further level of safety, the vehicles will have additional backup braking and steering systems which, in the highly unlikely event of a failure, the backup systems can be utilised by the CAVstar system without the 鈥榮afety driver鈥� needing to intervene.
It follows a live trial of the CAVstar system commissioned by Stagecoach early last year. A bus specially adapted by Fusion Processing navigated its way autonomously around the group鈥檚 Manchester depot, visiting a fuelling station and the bus wash before finding its parking spot.
