Lost in Transmission: Communicating for Safe Automated Vehicle Interactions in Cities

Lost in Transmission: Communicating for Safe Automated Vehicle Interactions in Cities


As automated vehicles (AVs) are increasingly deployed, they are expected to introduce a paradigm shift in transport. In cities, the transition from the current state of interactions between users – where human-to-human interactions prevail – to situations where humans will interact with more or less automated vehicles will likely impact how other public space users interact with road vehicles. The interpretation of other public space users' intent, the physical infrastructure, and digital elements play a crucial role in influencing AV interactions with other public space users.

This report provides principles and recommendations to ensure the communication of necessary information for the best interaction between public space users and automated systems. It assesses how meaningful information regarding public space and its use can be encoded and transmitted to AVs and how automated systems can acquire and use information to guide their actions and safely and beneficially manage interactions.
