Abstract

The U-turn in roads has been widely employed in the United States, Europe, and Central America. Based on the Highway 32 reconstruction and expansion project in Costa Rica, this paper analyzed and researched the U-turns based on Central American standards to introduce the U-turn design method. Meanwhile, it emphasized the application scope, selection characteristics, and design methods of the Central American region's U-turn design. The U-turns serving as a fine design method for solving left turn conflicts feature strong applicability, simple structure, and low cost. This paper can provide both guidance for similar designs based on European and American standards, and references for relevant designs in China.
