Spiral-Shaped Driveways: A Novel Method for Traffic Circles

Better design of large traffic circles is very important for the growing need of high quality travel. This paper presents a novel method for channeling the large traffic circles based on the spiral-shaped driveways, which is inspired by the Eight Diagram of Taoism. This channelization eliminates many potential conflict points as well as improves the traffic flux. Better utilization of the center island becomes possible. After applying the error-correcting mechanism, this design becomes more considerate and more branches can be added.
