Older people often have difficulty using public transportation. Ticket machines can be hard to operate, timetables can be confusing, and people using wheeled walkers or wheelchairs cannot get on or off a bus or tram without assistance. To remedy the situation, the Saarbahn transport operator in Saarbrücken founded “Mobia – Mobil bis ins Alter (Mobia – Mobile Into Old Age). Staff, who can be called via app easily, help people when barriers seem insurmountable. The staff members also use the technology themselves to coordinate their deployment.
