Zurich Airport in Switzerland has begun operating two fully autonomous electric buses within its facilities, in a notable step because the vehicles operate without a driver or safety supervisor on board. The operation is conducted according to Level 4 autonomous-driving standards, making the project one of the first European tests of this level in an actual airport environment, according to information published by the source.
The project was developed in cooperation with Chinese autonomous-vehicle specialist WeRide, and work on it began in March 2025. The two buses underwent gradual testing designed to verify that they met the regulatory requirements, safety conditions, and technical specifications associated with operating Level 4 systems in the European Union.
Initial Operation Without Passengers
Although the vehicles are permitted to operate without a safety supervisor inside the cabin, the first phase will not carry passengers. Raphaël Glaesener, senior innovation manager at Zurich Airport Ltd, said the initial journeys would again be conducted without passengers, and that employees would be able to use the buses after approximately four weeks of trial operation.
The absence of a human inside the vehicle does not mean that human oversight is completely absent. The two buses are monitored remotely, with the possibility of human intervention through remote operation when necessary. Each of the project’s partners, Swissport and Krummen Kerzers, also provides a dedicated remote operations supervisor.
A Limited Route Within Airport Operations
The operation forms part of a broader pilot program aimed at supporting the electrification of routine airport operations and reducing their emissions. Initially, the two buses will transport employees along a designated route that does not intersect with aircraft taxiways or runways, limiting the complexity of the operating environment compared with open passenger-transport routes.
According to Coralie Klaus Boecker, head of the ZRH Innovation Hub at Flughafen Zürich AG, the gradual automation of vehicles could help airports address the growing shortage of skilled labor. Airport management believes that establishing the operational and regulatory framework early will create the conditions needed to use automated vehicles safely, both for the airport and its partners.
Why Does This News Matter?
The practical change here is not merely the addition of electric buses, but the shift of autonomous-driving testing from trials involving an onboard supervisor to Level 4 field operation with remote oversight. This gives airports an opportunity to assess automation in repetitive, fixed-route tasks while retaining human intervention as a backup plan.
However, the scope of the trial remains limited: the initial operation will take place without passengers, and the route does not intersect with runways or aircraft taxiways. The source also does not specify the number of journeys, the program’s full duration, or the criteria for moving to broader operation. Therefore, the project alone does not establish the readiness of Level 4 technology for operation in all airport environments; rather, it provides an organized test of a specific use case under remote oversight.
