The future of public transport is increasingly leaning towards automation, addressing issues such as driver shortages, road safety, congestion, and carbon emissions. However, successful deployment requires seamless interaction between automated buses and other road users, such as cars, motorcycles, bicycles, and pedestrians. The Human Machine Interaction for Automated Public Transport Buses (InterAct) project, led by DAM Shuttles in conjunction with partners ADASTEC, Applied Autonomy, and Vy Buss, seeks to enhance communication between self-driving buses and pedestrians, cyclists, and motorists. Building on insights from the previously EIT Urban Mobility co-funded project LivingLAPT, which focused on small autonomous shuttles, InterAct pivots towards full-size, full-speed automated electric buses. These vehicles offer higher capacity and are further along in the development towards driving without a safety driver onboard, thus bringing public transport closer to a driverless future. (....)
