WIPO Patent Application WO1999026211
Kind Code:
A3
Abstract:
The present invention is to provide an intersection system which can do without, or drastically minimize, the frequency of having to wait for traffic signals in order to relieve traffic of congestion and minimize the land occupied by an intersection system. To attain this purpose the present invention provides System 1, which consists of two mutually intersecting roads, main road 1 and main road 2, each including a diverging section for cars making a left or right turn and a converging section for convergence of cars heading in the same direction after having taken their respective left or right turns; System 2, which has a ring-shape road on the upper and the lower level each at the central section of an intersection, and half-main-roads and entries being connected on the outer circumferences of these ring-shape roads, and System 3, which has a plate-shape road for right and left turns on an upper and lower level at the central section of an intersection, said plate-shape roads having half-main-roads and entrance roads built on the edges, and a minimum number of traffic lights, unavoidably, set up on said plate-shape roads or each entrance road for the benefit of cars advancing from all directions.
