About the Event
The State of Minnesota and the University of Minnesota have participated in the stop sign gap assistance portion of the USDOT's Intersection Decision Support effort and the Cooperative Intersection Collision Avoidance Systems effort. Minnesota's work included analyzing crash data from Minnesota intersections and establishing a test intersection for evaluating sensors and for data collection. The University of Minnesota team installed surveillance equipment at the test intersection and recorded driver gap selection behavior under various conditions. A human factors evaluation tested the viability of several concepts for signs that could be installed to provide gap assistance information to the driver. The effort has now been expanded to become a cooperative system where using wireless communications, the vehicle and the infrastructure work together to provide enhanced assistance to the driver.
