| Drivers' reactions to unexpected events are related to many different situation- and driver-related circumstances, such as driver characteristics, event urgency and type, and mental workload levels. The driving task is a hierarchical task with three interacting levels. This interaction becomes most clear on urban intersections, where all three levels are simultaneously and equally important. In normal driving, the interaction is mostly top-down, whereas bottom-up interaction comes into play only during or after unexpected events. Driving behaviour under varying conditions is studied, and used to give recommendations for the development of ADAS for urban intersection safety. |
