The goal of driver-assistant systems is to monitor the driver's decision-making and intervene where deemed necessary. In order to appropriately support the driver's subsequent driving manoeuvres, knowledge of the driver's intentions is required. Eye movements have been found to be an indicator of information gathering and therefore could be used to derive information about the driver's next planned objective. Here, the aim was to establish whether characteristic eye movement patterns precede particular driving manoeuvres. To this end, drivers' gaze behaviour has been analysed prior to the execution of different driving manoeuvres performed in real traffic using the DLR ViewCar. It was found that distinct gaze patterns preceded each of the driving manoeuvres analysed.
