A recent study demonstrates the significant potential for acceptance of driverless buses

The shortage of skilled workers poses challenges for both the logistics industry and local public transportation. And this is happening at a time when public transportation services are becoming increasingly important in the fight against climate change and congested city centers. Driverless buses and shuttle services could help counteract the labor shortage. And a recent study shows that such services are indeed well-received.

Operating buses profitably is particularly difficult during off-peak hours or outside major metropolitan areas. The costs for vehicles and staff must be covered by a relatively small number of passengers. The result: routes cannot be offered at all or only very rarely. Buses and minivans that operate without a driver—potentially even “on demand”—could bring more flexibility to public transit. And, for example, provide relief on heavily trafficked routes during rush hour. In Friedrichshafen and Mannheim, self-driving shuttle buses were successfully tested as part of the RABus project (“Real-World Laboratory for Automated Bus Operations”), with attendants on board solely for safety purposes.

Analysis of 1,600 test runs

The test phase was scientifically monitored by a team from the Institute of Transportation (IFV) at the Karlsruhe Institute of Technology (KIT). A recently published study now provides, for the first time, solid data on the acceptance of driverless shuttle buses. The study is based on the evaluation of over 1,600 test runs, focusing not only on the technical reliability of the autonomous shuttles in everyday use but also on public reaction and the necessary organizational framework. According to Professor Martin Kagerbauer of KIT, automated services can significantly increase mobility in rural areas, provided they operate reliably and users are informed about the capabilities and limitations of the vehicles.

A key finding of the study is that acceptance of driverless public transit services depends largely on the sense of safety during the ride. This applies both to the reliability of the technical systems and to protection against aggressive or threatening behavior by other passengers. A clearly visible interior, a direct connection to the control center, and understandable information during the ride are essential for passenger confidence. Only those who feel safe will see such systems as an alternative to their own car.
