Currently, most highly automated vehicles still require the presence of a human safety operator in the vehicle, and it is evident that automated driving without human “fallback” might be distant. On the other hand, having a human operator in the vehicle jeopardizes major anticipated benefits of automated driving – productivity. This is especially evident when it comes to heavy automated vehicles. To bridge this gap, stakeholders are exploring teleoperations technology, which enables highly automated vehicles to be remotely operated if necessary. But remote operation comes with its own challenges, both from technical and human behavior perspectives. In this SAFER co-financed prestudy, Scania and RISE have identified potential safety challenges and research gaps related to human behavior in the context of remote operation of heavy automated vehicles.
