摘要

After analyzing the serious impact of left-turn vehicle on intersection, this paper offers the means of traffic organization by being use of U-turn for carrying out left-turn vehicles at intersection. Meanwhile, the paper gives the calculation models and reference values of design parameters about distance from intersection to U-turn hatch in center isolation, turn radius, and path width. The results indicate the technique of U-turn can cancel left-turn vehicles at intersection, reduce phase numbers of the traffic signals and decrease delay to enhance capacity and continuity of the arteries.
