Abstract

The modern roundabout is different from the traditional roundabout or traffic ring. Because of its excellent performance in traffic safety, modern roundabouts have been widely used in Europe and the United States. In China, the modern roundabout is still in the stage of concept discussion, lacking practical application and applicability verification. Based on this, this paper built the first modern roundabout in China according to the concept of a modern roundabout and related technical requirements. According to the field observation data, the applicability of the modern roundabout island was evaluated from the perspectives of vehicle speed, loop behavior, truck buffer zone use, and non-motor vehicle adaptability, and the project was improved based on the evaluation results. The research results can provide a reference for the popularization and application of modern roundabouts in China.
