| 摘要： | The objective of this research was to determine the safety and operational effect of U-turns at unsignalized median openings. The safety performance of typical median opening designs were documented, and guidelines for the use, location, and design of unsignalized median openings were developed. The research scope included unsignalized median openings on all types of divided highways, but the focus of the research was on urban/suburban arterials because these present the greatest current challenge to highway agencies in access management. |
