    Report purpose is 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, which could result in drivers conducting important driving tasks in improper fashion or skipping certain tasks altogether. Seven distinct driving scenarios were investigated in the task analysis, and each scenario was successively separated into segments, tasks, and subtasks/information processing elements. The scenarios included in the analysis were: (1) left turn on green light, (2) left turn on yellow light, (3) straight on yellow light, (4) straight on green light, (5) right turn on green light, (6) right turn on red light, and (7) stop on red light.
