About the research

Safe intersection negotiation depends on drivers being able to recognize the presence of an intersection and then respond appropriately to applicable traffic control devices and prevailing conditions. When drivers are required to yield right-of-way to on-coming traffic, they also need to be able to identify and select appropriate gaps. Consequently, the proposed research for Phase I investigates the feasibility of answering the following research questions, which address the relationship between different stages of intersection negotiation and roadway and driver characteristics.

  • What is the relationship between rural intersection crash risk and driver, roadway, and environmental characteristics?
  • What is the relationship between intersection recognition and stopping behavior and intersection geometry and countermeasures?
  • What are the primary influences for appropriate scanning behavior and gap acceptance at rural intersections?
