Guest editorial: Decision making and control for connected and automated vehicles

As a transformative technology, connected and automated driving technology is expected to deal with the issues of traffic congestion and conflicts, and meanwhile to ensure the driving safety in intelligent transportation systems (ITS). In a connected driving environment, the motion states, surrounding traffic situations, and even the intentions and planned behaviours of driving can be shared between connected automated vehicles (CAVs). This enables the correct, reasonable, and effective decisions to be made for multi-vehicle interactions, particularly in complex situations.
