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.
