Abstract

A task analysis was conducted to identify the information processing bottlenecks that drivers face in specific intersection driving scenarios. These bottlenecks represent situations in which drivers may become "overloaded" by driving demands, possibly resulting in drivers improperly performing important driving tasks or skipping certain tasks altogether. The focus of this task analysis was on identifying the underlying information processing elements, including the perceptual, cognitive, and psychomotor subtasks associated with each individual driving task. A total of 7 distinct driving scenarios were investigated in the task analysis, with each scenario being successively decomposed into segments, tasks, and subtasks/information processing elements. Information processing bottlenecks were identified by analyzing converging information about workload levels, task sequencing and pacing, spatial distribution of required information, and other factors that mitigate or amplify taxing conditions.
