This report describes the results of a focus group study that explored driver attitudes and behaviors at intersections to assess the likely impacts of new or existing infrastructure-based technologies/countermeasures. The focus group study is part of a larger research project that will provide the Federal Highway Administration (FHWA) with information about roadway user attitudes and behaviors at intersections. Specifically, the information concerns driving performance, perceptual and cognitive bottlenecks, constraints that can negatively impact intersection safety, and engineering or educational countermeasures for intersection safety with the greatest likely impact on performance and safety.

16. Abstract The objective of this focus group study was to identify driver attitudes and behaviors related to intersection safety and to assess the likely impacts of new or existing infrastructure-based technologies/countermeasures. Four focus groups were conducted at each of three test sites: Washington, DC; Chicago, IL; and Seattle, WA. At each site, the four groups corresponded to the age/gender characteristics identified as important to this project. The four groups were:
