The driving task is a hierarchical task with three interacting levels. This interaction becomes most clear on urban intersections, where all levels are equally important. A behaviour simulation model of intersection driving will be developed, based on this hierarchical structure of the driving task. With this driver model, behavioural adaptation to ADAS on urban intersections can be studied.

Keywords: ADAS, behavioural adaptation, driver model, driving task, urban intersection

Background and problem definition

The three interacting levels of the driving taskThe effects of behavioural adaptation to ADAS for urban intersections are difficult to study before their introduction. Therefore, a driving behaviour simulation model will be developed, representing both normal intersection driving and interaction with ADAS. By using the structure of the driving task, it becomes possible to develop a complete intersection driving model and to extend driver models beyond single subtasks.

The driving task is a hierarchical task with three interacting levels. On the strategic level, the goals of the trip and the route are set. This determines the manoeuvres the driver has to make on the tactical level, which then determines the way the vehicle has to be controlled on the operational level (top-down). Alternatively, actions and decisions on a lower level can influence goals and priorities of higher level tasks in unexpected situations (bottom-up influence).

TNO driving simulatorMethodological approach

The driver model will be based on literature and driving simulator experiments. Initial experiments will focus on the interaction between levels of the driving task and on situations in which this interaction is most apparent. Further experiments will determine the effects of level interaction on driver performance, and study its influence on behavioural adaptation to ADAS.

Expected practical and scientific results

A behaviour simulation model of intersection driving will be developed. This will result in new knowledge about the structure of the highly complex driving task and the underlying processes of behavioural adaptation to ADAS.

Scientific and societal relevance

The behaviour simulation model will give new insight into driving behavior and the driving task. It can also be implemented into the driver module of simulation software (e.g., driving simulator software and microscopic traffic simulation models) to improve its performance.

New knowledge about behavioral adaptation to intersection ADAS can be used for further development of new ADA systems.
