Use of traffic control at low volume intersections in Minnesota. Final report

The Minnesota Department of Transportation (Mn/DOT) studied the use of traffic control at low volume intersections to determine the crash experience at intersections with stop, yield, and no control for low and high speed conditions, as well as analyzing crash data to develop conclusions and recommendations. Researchers sent survey forms to seven Mn/DOT districts, 87 countries, and 119 cities to collect intersection data and analyzed crash reports at selected intersections. At low speed intersections, those with stop control experienced the fewest number of accidents. However, yield control and no control can be effective methods of traffic control. At high speed intersections, the type of control had no appreciable effect on crash experience. The report suggested that uncontrolled and yield controlled intersections with three or more crashes associated with the right-of-way control in the last three years be studied to determine the need for more control.
