The site characteristics, traffic control used, and accidents occurring at 65 rural, high-speed intersections were summarized. The differences resulting when the right of way is controlled by stop signs versus a traffic signal are discussed. The factors contributing to the accidents as well as the characteristics of the accidents were analyzed. The data obtained at each intersection were summarized and recommendations, which could be used as a guide for implementing changes at other similar intersections, were made for the study locations. The accident analysis shows that providing the driver adequate warning of the intersection is of primary importance for this type of intersection. At signalized intersections, the need to provide a proper change interval and maximize the visibility of the signal heads are essential. The need to consider separate left-turn phasing also is shown.
