CA 2311120

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 tom and a converging section for convergence of cars heading in the same direction after having taken their respective left or right toms; 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.

L'invention concerne un système d'intersection qui évite les attentes aux feux de signalisation ou qui minimise radicalement leur fréquence, ce qui supprime les embouteillages et permet de diminuer la surface occupée par un système d'intersection. A cet effet, l'invention propose le système 1, qui comprend deux routes qui se coupent, la route principale 1 et la route principale 2, dont chacune comprend une partie divergente destinée aux voitures tournant à gauche ou à droite, et une partie convergente permettant la convergence des voitures qui vont dans la même direction après avoir tourné à gauche ou à droite; le système 2, qui comprend un rond-point sur le niveau supérieur et sur le niveau inférieur, dont chacun se trouve au centre d'une intersection, et des routes secondaires et des routes d'accès reliées à la circonférence externe desdits ronds-points; et le système 3, qui comprend une route en forme de plate-forme pour les voitures tournant à gauche ou à droite sur un niveau supérieur et sur un niveau inférieur, au centre d'une intersection, dont chacune est constituée de routes secondaires et de routes d'accès sur les côtés, et un nombre minimum de feux de signalisation, inévitablement, placés sur lesdites routes en forme de plate-formes ou sur chaque route d'accès et destinés aux voitures arrivant de toutes les directions.
