The Federal Highway Administration (FHWA) research addressed in this report was conducted as Task B.1 of the Integrated Program for the Interactive Highway Safety Design Model and Safety Research project (under contract number DTFH61-03-R-00128). Specifically, research was conducted to provide FHWA with information about key attitudes and behavioral influences in intersection driving performance, perceptual and cognitive bottlenecks, and constraints that can have a negative impact on intersection safety. The research also addresses engineering or educational countermeasures for intersection safety that have the greatest likely impact on performance and safety. This research includes a task analysis of driver performance at intersections, a literature review on human factors research as it relates to highway infrastructure, and focus group discussions that explore driver attitudes and behaviors at intersections. Figure 1 summarizes the information flow and shows how activities, processes, and results will be combined to produce this knowledge. (Author/publisher)
